There is dirty standing water inside dishwasher after it cycles. A few cycles before it stopped draining the dishwasher was making loud humming noises, then it quit draining and left standing water at bottom of dishwasher. I already cleaned the sump and removed the lower sprayer arm and everything appears to be okay. I also checked the drain hose and drain pump for obstruction but didn't find any obstruction. What else can I do fix this issue? Or, or is there a part that I need to fix the problem? Please help.
ANSWER Hello Phil,
If there are no clogs, the drain pump WD26X10039 will most likely have to be replaced because the impeller has to have damage incurred.
