PROBLEM
POSSIBLE CAUSE
SOLUTION
There are food
particles remaining
on dishes.
(Not cleaning
properly.)
The cycle selected was
unsuitable.
Select a cycle according to the number and soil
level of the dishes, as directed in this manual.
The water temperature is low.
Connect the water supply line to a hot water
supply. For best performance, the temperature of
the supplied water should be 120 ˚F (49 ˚C).
Low water pressure.
The water pressure should be between 20 and
120 psi (140-830 kPa).
The water is too hard.
Use a commercial dishwasher cleaner.
Use high-quality, fresh detergent with rinse aid.
Clean the fi lter at least once per month. (See
page
28
.)
Use a water softener additive designed for
dishwashers.
Dishwasher detergent was not
used.
Use automatic dishwasher detergent.
We recommend a powder or gel type
dishwasher detergent.
Detergent remains in the
dispenser.
Make sure large items such as cookie sheets,
cutting boards, or contaners, etc. are not
blocking the detergent dispenser and preventing
it from opening properly.
Rearrange the dishes so they do not interfere
with detergent dispenser operation.
There is no rinse aid.
Check the dispenser and add rinse aid.
Use liquid type rinse aid.
A nozzle is clogged.
Clean the nozzle. See pages
26
and
27
.
The dishes are improperly
loaded.
Too many dishes have been
loaded.
Rearrange the dishes so they do not interfere
with nozzle rotation and detergent dispenser
operation.
Load only an appropriate number of dishes.
Load your dishes as recommended.

Filter could be clogged.
(Food soils remain on the fi lter.)
Scrape food from dishes prior to loading. (Do not

with a light fi lm.
The water supplied is soft and
too much detergent was used.
Underload the dishwasher and use a rinse aid to
minimize this.
Aluminum dishes were
included in the wash load.
Remove the marks on the dishes using a low
sensitivity cleaner.

or brown fi lm on
the inside of the
