Dishwasher fails to start after filling with water.
You will want to check the pump assembly to make sure that there is power getting to the circulation pump. If there is power to it then the pump is faulty and would need to be replaced.
Dishwasher humming but water not pumping out. What part do I need?
If the unit is not pumping the water out of the unit then you will want to check the drain pump to make sure that it is not clogged and make sure that the impeller is not damaged. If this checks ok then check the drain to make sure that it is not clogged. If all checks ok then the drain pump WD26X10039 would most likely be the cause of failure.
