Thermador Dishwasher Not Draining? Pound Ridge Expert Guide

Why Your Thermador Dishwasher Won't Drain

Finding standing water at the bottom of your Thermador dishwasher is frustrating. Here's what might be causing the problem and how our Pound Ridge technicians can help.

Check These First

1. Filter and Drain Area

Remove the bottom rack and check for debris in the filter and drain area. Food particles, broken glass, or utensils can block drainage.

2. Garbage Disposal Connection

If your dishwasher drains through the garbage disposal, a clogged disposal can prevent drainage. Run the disposal before starting a wash cycle.

3. Air Gap or High Loop

Check that the air gap (if installed) isn't clogged, and the drain hose maintains a high loop under the sink.

Common Causes of Drainage Failure

Clogged Drain Pump

The drain pump forces water out of the dishwasher. Debris can jam the impeller or a failed motor prevents operation.

Faulty Drain Valve

Some models have a drain valve that opens to allow water out. If stuck closed, water can't exit.

Control Board Issues

The control board signals the drain pump to operate. Electronic failures can interrupt this process.

Kinked or Clogged Drain Hose

Check under the sink for kinks in the drain hose, or internal blockages from grease buildup.
