Thermador E24 Drainage Fault Fix

Error Codes · 2026-11-14

For Thermador owners seeing thermador e24 drainage fault fix, the fault usually comes back to a blocked drain pump, clogged filter, or kinked drain hose. This article explains what to check, the diagnostic path we follow, and the genuine OEM parts involved.

Where the Water Is Stuck

An E24 on a Thermador dishwasher is a drainage fault: the machine cannot clear its water in the expected time. The most frequent causes are a clogged filter, a drain hose with a collapsed high loop or a kink, a blocked air gap at the sink, or debris jamming the drain pump impeller. Standing water in the tub at the end of a cycle is the visible sign.

Working the Drain Path

We work the whole drain path in order: clean the filter basket and sump, check the hose routing and the air gap, and confirm the pump spins freely and pumps to spec. Often the fix is a cleaning and a rerouted hose rather than a part, but a failed drain pump gets replaced with a model-specific unit. Testing a full drain cycle before we close out confirms the E24 is gone for good.
