MAINTENANCE

Deliming

Your dishwasher should be delimed regularly as required. This will depend on the mineral

content of your water.

Inspect your machine interior for lime deposits. If deliming is required, a deliming agent should

be used for best results.

If you have the chemical sanitizing model (401-LT), carefully follow the following procedure

before deliming:

DANGER:

Deliming solution or other acids must not come in contact with household bleach (sodium

hypochlorite) or any chemicals containing chlorine, iodine, bromine, or fluorine. Mixing

will cause hazardous gases to form. Skin contact with deliming solutions can cause severe

irritation and possible chemical burns. Consult your chemical supplier for specific safety

precautions.

1. Remove the sanitizer tube from the container. Place the tube into a container of hot water.

2. Depress and hold the SANITIZER prime switch (located on the front panel) until all

sanitizer has been purged from the hoses.

3. Close the door and depress the door latch. Complete two operating cycles to purge the

machine of all sanitizer.

Deliming Procedure

Complete the following procedure to delime your machine:

1. Add the delime chemical to wash the tank (per chemical supplier specifications).

2. Close and latch the door.

3. The dishwasher will complete a regular cycle.

4. Check the deliming results and repeat if necessary per the chemical supplier’s

specifications.

5. Operate the dishwasher for at least four complete cycles to purge the machine of any

deliming chemicals.

6. For chemical sanitizing Model 401-LT, re-prime sanitizer chemical line and run an

additional cycle to flush any excess sanitizer from machine.
