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 20and
120 psi (140-830 kPa).
The water is too hard. Use a commercial dishwasher cleaner.
Use high-quality, fresh detergent with rinse aid.

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
