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.
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.
