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.
Dishwasher detergent
was not used.
• Use automatic dishwasher detergent.
• We recommend a powder type or multi-
function tablet 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.
