DW9900R_DD68-00209A-00_EN.indd 47
Possible cause
The cycle selected was
unsuitable.
The water temperature is
low.
Low water pressure.
The water is too hard.
Dishwasher detergent
was not used.
Detergent remains in the
dispenser.
Solution
• Select a cycle according to the number
and soil level of the dishes, as directed
in this manual.
• 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).
• The water pressure should be between
20 and 120 psi (140-830 kPa).
• Use a commercial dishwasher cleaner.
• Use high-quality, fresh detergent with
rinse aid.
• Use automatic dishwasher detergent.
• We recommend a powder type or multi-
function tablet dishwasher detergent.
• 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.
