Deliming Procedure

MAINTENANCE

Deliming

Your dishwasher should be delimed regularly. The frequency 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.

!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.

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

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.

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.Drain the dishwasher. Deliming is complete.
