Why is there standing water in my dishwasher?

Standing water often indicates a problem with the dishwasher's drainage system. This could be due to a clogged filter, a kinked or blocked drain hose, or a faulty drain pump. Inspecting these components can help diagnose the issue.

Can I clean my dishwasher drain pump instead of replacing it?

While it is possible to clear minor obstructions from a drain pump impeller, a pump that is failing due to motor wear or internal electrical issues typically requires replacement. Cleaning may resolve issues caused by debris, but not mechanical failure.

How do I know if my drain pump is bad or if it's just a clog?

If you hear the pump motor running but no water is draining, it might be a clog. If you hear no sound or only a humming noise during the drain cycle and water remains, the pump itself is likely faulty. Check the drain hose and air gap for clogs first.
