Ed for Model Number WDT790SAYM1 Whirlpool dishwasher. Have replaced drain pump. Am going to replace inlet valve. Hoping these cover problem. Problem is that some water comes in (from the side) but apparently not enough or not forcefully enough. Soap drops and sits in bottom and does not dissolve, and water sits and will partially drain. After replacing pump, now the lower part partially spins and there appears to be more water going through but not fully clear. Soap still just drops and sits. Any other thoughts besides inlet valve? Thanks.
Answer Ed sounds like two problems, not enough water and water that's not hot enough. Water supply from under the sink should be a 3/8 in. (IDI) copper tube or flex/plex water supply line and deliver 7 GPM at the dishwasher water inlet valve. The water temperature should be 120 dgrs.F. on the initial fill of a regular wash cycle and measure 1/2 to 3/4 in. deep in the center of the tub. Thanks, Read More...
