Once the option adjustment mode is entered, a beep is emitted and the LCD displays the letters rA. Pushing the START/PAUSE button scrolls through the options and allows changes as follows:Rinse Aid Setup (rA). Water Supply Hardness Setup (hd). Auto Power Option (AP). End of Cycle Beeps (EC). Closed Drawer Option (Ld). Clean/Dirty Dish Symbol (dS). Dry Enhancement Option (LH). Integrated:- On an integrated DishDrawer where there is no display, the option chosen is indicated by the lights showing on the integrated badge as follows:Rinse Aid Setup (red light above START/PAUSE button). Water Supply Hardness (green light above START/PAUSE button). Auto Power Option (orange light above START/PAUSE button). End of Cycle Beeps (green light above START/PAUSE and red light above Keylock) button). Closed Drawer Option (red light above START/PAUSE and KEYLOCK buttons). Clean/Dirty Dish Symbol (not available on Integrated models). Dry Enhancement Option (orange light above START/PAUSE button, ECO light is red). Push POWER at any time to exit this setup mode. Integrated:- On an integrated DishDrawer when one of the options is changed, it is indicated by the red wash cycle LEDs on the secondary control panel. If an option is turned on, then all the LEDs turn on, and if an option is turned off, all the LEDs turn off. 4 Rinse Aid Setup (rA) The current rinse aid setting is shown using the red LED’s on the touch switch panel. The amount of rinse aid dispensed into a rinse cycle can be varied to suit the level of hardness of the local water supply. It is adjusted for 1 - 5 dispenser levels (1 = approx 0.5mls (1/10) teaspoon of rinse aid, 5 = approx. 2.5mls (1½) teaspoon of rinse aid). Push KEYLOCK to advance the rinse aid setting. Once the desired setting is achieved, push POWER to exit. The rinse aid index is stored in EE memory, so even with the power removed, the rinse aid level is retained. Water Supply Hardness Setup (hd) (Where Fitted) The current supply hardness setting is shown using the red LED’s on the touch switch panel. One of 5 settings should be selected according to the known hardness of the supply water. Each setting is appropriate for the following water supply hardness: No LED Water Softener turned off, continuous bypass of softener 1 LED 150-250 ppm water supply hardness 2 LEDs 250-350 ppm water supply hardness 3 LEDs 350-450 ppm water supply hardness 4 LEDs 450-550 ppm water supply hardness 5 LEDs 550-625 ppm water supply hardness Push KEYLOCK to advance the Water Softener setting. Once the desired setting has been achieved push POWER to exit. Selection of a setting affects how the Electronic Controller diverts supply water, how much water is treated, and how much salt is used in regeneration, in a manner that optimises the performance of the Water Softener. Auto Power Option (AP) The automatic power up sequence that occurs when the tub is opened can be turned on or off using the KEYLOCK button. If the scrubbing brush is showing on the LCD, then the auto power up sequence will occur when the tub is opened. If the scrubbing brush is not showing, then the DishDrawer will not automatically power up when the tub is opened (the customer will need to push the power button each time they wish to use the DishDrawer). Push POWER to exit when the desired setting has been selected. 5 End of Cycle Beeps (EC) The six beeps that occur at the end of the cycle can be turned on or off using the KEYLOCK button. If the scrubbing brush is showing on the LCD, then the end of cycle beeps are activated. If the scrubbing brush is not showing, then the end of cycle beeps are deactivated. Push POWER to exit when the desired setting has been selected. Closed Drawer Option (Ld) The closed drawer option can be turned on or off using the KEYLOCK button. If the scrubbing brush is showing on the LCD, then the closed drawer option is selected and it will keep the DishDrawer locked at all times by bringing the lid down. When this mode is selected the customer needs to push the POWER button to lift the lid whenever they want to open the drawer. When they close the drawer again, the lid comes down automatically after 30 seconds and locks the tub. If the scrubbing brush is not showing, then the closed drawer option is deactivated. Push POWER to exit when the desired setting has been selected. Clean/Dirty Dish Symbol (dS) (Not available on integrated models) The clean/dirty dish symbol can be turned on or off using the KEYLOCK button. If the scrubbing brush is showing on the LCD, then the clean/dirty dish option is selected. This means that the end of cycle clean dishes symbol will remain in the LCD display until the power button is pressed to clear it. If the scrubbing brush is not showing, then the clean/dirty dish symbol will disappear when the drawer is first opened at the end of a cycle (factory setting). Push POWER to exit when the desired setting has been selected. Dry Enhancement Option (LH) (Available in prefinished products from Serial Number MEM741743, manufactured after 21/5/03, software version 3.2.06. Estimated to be available in integrated models from October 2003, software version 3.2.07.) Dry enhancement option can be turned on or off using the KEYLOCK button. If the scrubbing brush is showing on the LCD, then the dry enhancement option is selected. This means the lid will stay down and the drying fan will continue running for 4 hours after the wash program completes. 6 If the customer wishes to open or stop the DishDrawer during this 4 hour period, they can do so by pushing the POWER or START/PAUSE button. This will reset the feature until the end of the next wash program. Push POWER to exit when the desired setting has been selected. 7 DIAGNOSTICS DishDrawer Diagnostics Dishwasher Diagnostics can only be entered in Power Off mode, ie. when there is no display on the LCD or the badge LED’s are off. Diagnostics is entered by holding the KEYLOCK and START/PAUSE buttons simultaneously for 5 seconds. Ensure that KEYLOCK is pushed first. There are currently four levels of diagnostics. To move to the next level push POWER. To enter a level push START/PAUSE. Once a level has been entered, pushing POWER will exit diagnostics completely. If no level is entered, then the display will cycle through the four levels and exit after the last. On entering diagnostic mode, the first level is the Display/Download Mode. Display/Download Mode In this mode, all LED’s and LCD segments (except keylock) are illuminated. Optical LED Download/Fault Display An optical data download is available here to download all EE data to a PC or Palm PC via the lower tub-home sensor light pipe. Hold the reader pen over the lower tub-home sensor light pipe and press START/PAUSE to initiate the download. A short beep indicates the start and finish of download. The last two faults are displayed on the LCD (secondary control panel LEDs for integrated models) during the optical download. The Current Fault code is displayed first followed by the Previous Fault Code. To read the Fault Code on the secondary display, refer to page 7 on Fault Codes. Clearing Fault Logs To clear the Current Fault, press the KEYLOCK button until a beep is sounded. This action moves the Current Fault into the Previous Fault while clearing the Current Fault. To Clear the Previous Fault press KEYLOCK once more until the beep is sounded. Warning: Once a fault has been cleared, it is permanently removed from memory and cannot be recovered. Press POWER to advance to the next level. 8 Hardware Output Diagnostic Test Mode This level tests all the hardware outputs and inputs. The LCD display shows “HO”. Press POWER to skip hardware diagnostics and advance to the next level. Press START/PAUSE to enter hardware diagnostics. Once hardware diagnostics has been entered, the current hardware output being tested is indicated by letters in the LCD display, and for integrated models the LEDs on the touch switch panel using binary encoding, as shown in the table on the next page. Different combinations of outputs can be switched on or off together, but the controller will prevent higher current drawing components such as the wash pump and the lid motors being turned on together. Press START/PAUSE to advance to the next hardware output. Press KEYLOCK to turn the currently displayed output on or off. If the scrubbing brush symbol (green LED above start/pause button on integrated models) is displayed, then that output has been switched on, and if it is not displayed then that output is off. Press POWER to Exit at any time (all outputs will be switched off on exit). 9 As mentioned on the previous page, the LCD display and touch switch panel LEDs are illuminated to correspond to a particular hardware device. The following table details the display order of the test.

WARNING: In diagnostic mode there is no component protection. Therefore take care when running individual components not to overload them. It is advisable to avoid turning the element on without filling the tub with water first. NB : No fault codes will come up while in diagnostics mode. Tub Home Sensor Test: At any time during HO test mode, the Keylock symbol on the LCD display (Keylock LED on integrated badge) indicates the tub position. On = Closed, Off = Open. 10 Fast Test Cycle This level runs a 5 minute fast test cycle. Press POWER to skip Fast Test Cycle and advance to the next level. Press START/PAUSE to enter Fast Test cycle. Once Fast Test Cycle is selected the DishDrawer goes into standby mode and 5 minutes will be showing on the display. The test cycle is started by pushing START/PAUSE and the following components are run during the 5 minute cycle that follows:- Lid motors, fill valve, wash motor, element, drain motor. Press POWER to Exit at any time. Continuous Cycle Test Mode In this level the DishDrawer can be run continuously in any wash cycle. Once the cycle has finished, the DishDrawer automatically restarts the same wash cycle. Press POWER to skip Continuous Cycle. As this is the last level, doing this will exit diagnostics. Press START/PAUSE to enter Continuous Cycle. Once selected, the LCD backlight flashes on and off to indicate the DishDrawer is in continuous cycle and the cycle starts straight away (for integrated models the LED above the start/pause button will be orange instead of green to indicate the DishDrawer is running in continuous cycle). It will run the last cycle that had been selected prior to going into diagnostics mode. If it is desired to run a different cycle, exit diagnostics, turn the DishDrawer on as normal and select the cycle required. Then turn the DishDrawer off again, re-enter diagnostics and restart the Continuous Cycle as above. Press POWER to Exit at any time. 11 Cycle Count Retrieval (not available on integrated models) To display the cycle count on the LCD screen, pause the DishDrawer while running a Continuous Cycle. The two bytes of the cycle count will be displayed alternately, in syncronisation with the changing backlight. The Low byte is displayed when the backlight is off. The High byte is displayed when the backlight is on. To calculate the Total DishDrawer cycle count use the formula below. Cycle_Count = (200 x High_byte) + Low_byte. Eg. Low_byte = 156 High_byte = 2 Cycle_count = (200 x 2) + 156 = 556. Temperature & Voltage Display Mode (Not available on integrated models) During a wash cycle, the current water temperature or the power supply rail voltage of the controller can be displayed on the LCD instead of the time remaining. To enter temperature/voltage display mode, start a wash cycle as normal. Initiate a keylock by pushing and holding the KEYLOCK button for 4 seconds Once in keylock mode, push and hold START/PAUSE for 8 seconds to enter temperature display mode. The display now alternates between a °C symbol and the water temperature. Pressing the START/PAUSE again changes the display to alternate between an °E symbol and the power supply rail voltage of the controller. To cancel temperature/voltage display mode, press the POWER button. Show Off/Showroom Wash Mode This mode initiates a shop show off display and wash operation demonstration. With the DishDrawer powered up and turned on, the show off mode is entered by holding the ECO and POWER buttons simultaneously for 5 seconds. Ensure that ECO is pushed first. 12 The DishDrawer is now in the Show Off mode and cycles through all of the LED & LCD segments while pulsing the LCD backlight on and off. Pressing the POWER button now puts the DishDrawer into the Showroom Wash mode. Before running this mode the tub should be filled with water until it is just touching the underside of the spray arm. The Showroom Wash is started by pushing the START/PAUSE button whereby the following cycle is run:The lid is pulled down. The wash motor starts and runs for 4 minutes. The wash motor stops. The lid is lifted. The display counts down to zero throughout this cycle. The DishDrawer turns off at the end of this cycle. The DishDrawer is still in the Showroom wash mode however, and it can be re-run by pushing POWER and then START/PAUSE. Once Show Off/Showroom Wash mode has been initiated, the mains power must be removed to exit out. 13 DIAGNOSTICS QUICK REFERENCE CHARTS Fault Display/Download Mode Press and hold KEYLOCK, then START/PAUSE for 5 seconds. All LEDs & LCD segments except Keylock are illuminated. Press START/PAUSE. This initiates Pen upload via lower tub-home light pipe. At the same time the current and then the previous fault code will be displayed in the LCD screen and on the secondary control panel LEDs. To read the fault code on the secondary display, refer to page 7 on Fault Codes. Press KEYLOCK. This will clear current fault code. Note: if Keylock is pressed again, the previous fault code will be cleared. Press POWER to exit. 14 Hardware Output Test Mode Press and hold KEYLOCK, then START/PAUSE for 5 seconds. All LEDs & LCD segments except Keylock are illuminated. Press POWER once. “HO” will show in the display (integrated: Heavy, Normal, Fast, Delicate, Rinse LEDs showing) Press START/PAUSE.

Temperature & Voltage Display Mode (Not available on integrated models) Start a wash cycle running. Press & hold KEYLOCK for 4 seconds. Keylock will be activated. Press & hold START/PAUSE for 8 seconds. LCD will now alternate between °C symbol & the water temperature. Press START/PAUSE. LCD will now alternate between °E symbol & the controllers rail voltage. Press & hold KEYLOCK for 4 seconds. Keylock is deactivated. Press POWER to exit. 16 Fault Codes The faults are displayed in the LCD as one of 5 F (fatal) faults or 1 U (user) fault along with the symbol of a spanner. A fatal fault will usually require the assistance of a qualified service person, while a U1 user fault indicates the machine had failed to prime within a certain length of time usually because the tap has not been turned on. For this reason at the same time a U1 comes up in the display we also show the symbol of a tap. In the Integrated models, an LCD is not available, and the presence of a fault is indicated by a Red centre LED, with the fault number indicated on the touch switch panel with Red LEDs. Once a fault is repaired it can be cleared by pressing the POWER button. If the fault is still present then it will not clear. A fatal or user fault is accompanied by a continuous pulsating beep, which can be turned off by pressing either the POWER, START/PAUSE, or KEY LOCK button. The last two faults are logged into EE memory. The other U (user) faults have been removed. The old U2 fault, which was the tub forced open during a cycle, has been removed completely. Instead, if the tub is forced open, the product simply pauses as if someone had pressed the start/pause button. The old U3 fault, which indicated a failure to drain, i.e. water left in the tub, will not show up a fault and the DishDrawer will continue through the cycle. 17 Fault Code Description Chart The following chart is a quick reference guide on fault codes. To read a fault code off an integrated model, refer to the LED Display column on the chart below. The LED that has activated on the secondary display indicates which fault code has occurred.

Cause of problem (2) How to resolve the problem The product is being over loaded or incorrectly loaded with dishes. Advise customer of correct loading. Cause of problem (3) How to resolve the problem Customer is selecting the wrong wash cycle for the soil level on the dishes. Advise customer about reduced water temperatures (up to 20ºC / 70°F lower) and wash times when using Fast and Eco cycles. Customers Complaint Coffee/Tea Stains left in Cups Cause of Not enough detergent being used. To remove these problem (1) stains requires a stronger concentration of detergent in the water. More detergent is also required in hard water areas as minerals in the hard water reduce the effectiveness of the detergent. How to resolve Fill the main-wash detergent cup to the top & for best the problem results also fill the pre-wash detergent cup. Run on normal or heavy cycles not Eco. Cause of problem (2) How to resolve the problem The product is being over loaded which is preventing water reaching the cups on the upper cup racks. Advise customer of correct loading. 26 Customers Complaint Dishes have blotchy marks on them that look like water stain marks not food Cause of Not enough rinse aid being used. The water is not soft problem enough during the final rinse and therefore hard water droplets containing impurities are drying on the dishes instead of running off during the dry cycle. How to resolve Confirm that the customer is using rinse aid. the problem The rinse aid may need to be turned up to a higher setting (4 or 5 lights) and for optimum dry performance run the DishDrawer on normal or heavy cycles not Eco. Check that the rinse aid dispenser is dispensing correctly in diagnostics. Customers Complaint Glasses & Cutlery have a Cloudy White film on them and/or Plates have a White Chalky film on them Cause of Hard water & not enough detergent being used. problem Minerals from the water are building up on the dishes or the Water Softener is not set to the correct Water Hardness Level or is faulty. How to resolve Once this film forms on the dishes it cannot be the problem removed by normal running in the dishwasher. The dishes will need to be cleaned by soaking them in an acidic solution such as white vinegar and water. Where a Water Softener is not fitted; To prevent the build up re-occurring the customer will need to fill both the main-wash & pre-wash detergent cups to the top with a power detergent and we would recommend running on normal cycles. In problem areas with very hard water the customer may need to use a detergent additive designed for use in hard water areas or fit a water softener to the incoming water supply. 27 Where a Water Softener is fitted; Set the Water Softener for the correct local Water Supply hardness. Check that the Water Softener is functioning correctly in Diagnostics; C1 Water Softener Diverter Valve In hardware output Diagnostics Test Mode FU – turn the Fill Water Valve on P2 – turn the Motor Drain on C1 – Water Softener Diverter Valve On – water bypasses the resin tank Off – water flows through the resin tank C2 Water Softener Brine Pump Turn the Brine Pump on in Diagnostics mode. Observe a small quantity of water (approx. 30 ml per min.) flowing out the bottom of the dispenser. (Drop the Dispenser Door down to observe this.) Observe a change in the water level (approximately 120ml per 4 min.) in the Salt Reservoir. The Reservoir should pump dry of water in this time. Note:- Fill the Salt Reservoir with Salt (and then water if not already) before performing this test. Pipe Interrupter (Air Break) Function A critical component in the performance of the Water Softener is the pipe Interrupter (PI). There is a certain amount of spray leakage from the PI which is used to provide water to the Salt Reservoir. If the spray is inadequate, there will be insufficient water in the Salt Reservoir to make Brine. If there is too much spray then the excess bypasses the Water Softener and defeats the softening process by pouring untreated water into the Tub. To check that the amount spray leakage is appropriate:- 28 Fill the Salt Reservoir with water. In diagnostics mode, Turn on the Fill Water Valve, and the Motor Drain. Water will flow out of the Dispenser into the Tub, as well as out of the Water Softener Overflow into the Tub. Observe the flow from the Water Softener Overflow (beside the Dispenser). There should be a trickle (25100 ml per minute). With experience you can guess what is appropriate. If the trickle is outside these rates, replace the softener as the PI is faulty.

(A quick way to check that there is water in the Salt Reservoir is to remove the Salt Bung and test the water level by placing your finger down through the opening.)
