Power Button Features LDF9810ST – Steam Dishwasher 11 T-7 Installation Installation is covered briefly for the servicer who may need to uninstall and reinstall the dishwasher for repairs. For new installations, please refer to the installation guide that was supplied with the dishwasher. LDF9810ST – Steam Dishwasher 12 T-8 Installation Drill a 1½” hole on either side to allow for the drain hose, water supply hose, and electrical cable. The opening must be in an area within 4” (100 mm) of the back wall and 4” (100 mm) of the floor. If there is a floor in the cabinet under the sink, it will be necessary to cut through it to connect the water, drain, and electrical cable under the sink. LDF9810ST – Steam Dishwasher 13 T-8 Installation The dishwasher must be supplied with 120 VAC 60 Hz 1Ø current as indicated on the rating plate and connected to a properly fused and grounded dedicated 20-amp circuit. The wire or water supply can be fed from either side, and both from the same side, depending upon source location. They must be run in the channels under the dishwasher, as shown in the drawing. LDF9810ST – Steam Dishwasher 14 T-8 Electrical Installation The dishwasher can be hardwired if necessary and if permitted by local code. We recommend the use of a dishwasher installation kit, available at most hardware and home supply stored. This kit includes a cordset, a flexible water supply line, and the elbow connector necessary to connect it. Using a cordset requires an electric outlet under the sink accessible when the dishwasher is installed. The cordset makes it easier to disconnect the dishwasher from power while working on it and makes removal and replacement easier. As stated earlier, installation requires a properly fused and grounded dedicated circuit. LDF9810ST – Steam Dishwasher 15 T-9 Water Supply Preparation The dishwasher may be connected to either HOT or COLD water. If the hot water can not maintained below 149° F, the dishwasher must be connected to the cold water supply. Lay out the water supply line as indicated on page 14 of the training manual. Use sealing tape or joint compound to avoid leaks. LDF9810ST – Steam Dishwasher 16 T-9 Installation Adjust the legs to the required height for the dishwasher to slide under the countertop and be level. Check the level using a spirit level. LDF9810ST – Steam Dishwasher 17 T-9 Installation Attach the leveling feet kit to allow for fine tuning when the dishwasher is pushed into place. LDF9810ST – Steam Dishwasher 18 T-9 To complete the installation: Installation Remove the lower cover. Make sure the legs are adjusted and the dishwasher is level. Lay out the electrical cable, water supply tube, and drain hose as shown. Slide the dishwasher carefully back into place. Make the appropriate connections, as directed on subsequent slides. LDF9810ST – Steam Dishwasher 19 T-9 Drain Connection The drain hose must be connected in a manner that meets the local plumbing code. If the end of the drain hose does not fit the available connector, an adapter may be obtained from a local hardware or plumbing supplier. LDF9810ST – Steam Dishwasher 20 T-10 Drain Connection The rubber end can be cut off for the correct size attachment. LDF9810ST – Steam Dishwasher 21 T-10 Drain Connection Most garbage disposers have a dishwasher drain fitting built in to them. If your installation does not include a disposer, you can use a special tail piece with a drain attachment available at most hardware and home supply stores. LDF9810ST – Steam Dishwasher 22 T-10 Water Connection Turn off the water supply and connect the elbow to the inlet valve. Connect the flexible supply tube to the elbow. Use sealing tape to make all connections. Make sure the supply line is not kinked. LDF9810ST – Steam Dishwasher 23 T-10 Electrical Connection Use wire connectors and replace the cover on the junction box. (12/2 w/ ground, 20-amps) LDF9810ST – Steam Dishwasher 24 T-10 Final Installation 1. Turn on the water at the valve under the sink. 2. Turn on the power at the fuse or breaker (or plug in the cordset at the outlet under the sink. 3. Run the dishwasher through one QUICK cycle to check the operation and to check for water leaks. 4. Replace the lower cover. When the door is closed, the top edge with the controls should be under the countertop.

By selecting SOFT SPRAY for the upper rack and STRONG SPRAY for the lower rack, you can wash delicate items like stemware on top while washing pots and pans on the bottom. LDF9810ST – Steam Dishwasher 31 T-13 Dual Intensity Spray Wash 1. Press and hold SPRAY to illuminate the indicator. 2. Press SPRAY to set the intensity for the upper rack. (Strong/Medium/Soft/Off) 3.

Select other options. 7. Close the door. 8. The dishwasher will start. LDF9810ST – Steam Dishwasher 32 T-13 Adding Detergent Detergent must be added to the dispenser before the start of every cycle except RINSE ONLY. The detergent chamber holds 1.4 oz. (40 g) when full. If the dishes are only moderately dirty, it might be possible to use less detergent. LDF9810ST – Steam Dishwasher 33 T-14 Adding Detergent Press the latch button to open the detergent chamber. LDF9810ST – Steam Dishwasher 34 T-14 Adding Detergent Add detergent in the proper amount. (See chart, later slide.) Close the cover and be sure the latch clicks. LDF9810ST – Steam Dishwasher 35 T-14 Adding Detergent If pre-wash cycle is selected (in SOAK or POWER SCRUB only), add the appropriate amount of pre-wash detergent in the recess on the door cover. When you close the dishwasher door, the detergent will fall into the tub. NOTE: Too much detergent can leave a film on the dishes. LDF9810ST – Steam Dishwasher 36 T-14 Detergent Chart CYCLE Amt. Detergent Soak Full (0.35 oz.) ¾ full (1.05 oz.) Power Scrub Full (0.35 oz.) ¾ full (1.05 oz.) Normal None ½ full (0.7 oz.) Steam Delicate None ½ full (0.7 oz.) Quick None ¼ full (0.3 oz.) Rinse Only None ½ full (0.7 oz.) LDF9810ST – Steam Dishwasher 37 T-14 Adding Rinse Aid Turn the round cap counterclockwise and remove it. LDF9810ST – Steam Dishwasher 38 T-15 Adding Rinse Aid Fill the reservoir. It holds 4.8 oz. (145 ml) Replace the cap and lock it. LDF9810ST – Steam Dishwasher 39 T-15 Adding Rinse Aid Adjust the rinse-aid setting as necessary. LDF9810ST – Steam Dishwasher 40 T-15 Adding Rinse Aid The factory setting for rinse aid dispensing is 3. Too little rinse aid contributes to spotting, streaking, and poor drying performance. Too much rinse aid causes foaming, which leads to poor washing performance. How often you refill the dispenser depends upon your washing habits, including the rinse aid setting, the number of loads per month you wash, and other factors. The indicator light will illuminate when the level is low at the start of a load.
