Fast diagnosis and repair when a dishwasher leaves standing water: clogged filters, drain hoses, pumps, disposals and air gaps.
Standing water in the bottom of the dishwasher is both gross and a sign that something is blocked or broken. The most common cause is simple: food and debris in the filter or drain. But a dishwasher that will not drain can also be a symptom of a clogged garbage disposal, a kinked drain hose, a bad air gap, a failed drain pump or a stuck check valve. In Nashville kitchens where the dishwasher and disposal share a drain, finding the real cause takes a methodical approach.
We start with the filter and sump, then check the drain hose, high loop or air gap, the garbage disposal knockout plug on new installations, the check valve and the drain pump itself. We clear the clog, test the pump with a full drain cycle and explain what we found, so you know whether it was a simple blockage, an installation issue or a failed part. We also show you how to keep the filter clean.
A clogged filter and trapped food are the most frequent cause, and we clean and test them.
Kinked hoses, missing high loops and blocked air gaps let dirty water flow back or stop draining.
A new disposal with an uncut knockout plug blocks the dishwasher drain, and we check for it.
A jammed or failed pump motor is replaced and tested.
