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 (501LT or 501UTL), 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 clear
water enters the tank through the fill air gap.
3. Close the door and depress the door latch. Complete two operating cycles to purge the
machine of all sanitizer.
Deliming Process
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. On models 501HT, 501HTN, 501UT and 501UTLC depress the EXTENDED
WASH/DELIME switch on the front panel as soon as the cycle starts. On models 501LT
and 501UTL, proceed to step 5 of this procedure.
NOTE:
The EXTENDED wash/delime switch will operate only during the wash cycle.
When this switch is in the ON position, the machine stays in the wash cycle until the
switch is OFF. After switching to OFF, the machine will finish the cycle.
4. After 2-1/2 to 3 minutes (or as long as required), turn off the EXTENDED WASH/
DELIME switch. The machine will finish a complete cycle.
5. Complete two cycles with the machine empty to purge the machine of all delime chemicals.
6. Deliming is complete.
