Thermador Dishwasher Error Code E24
Drain fault / water not clearing
Common Causes
- 1Drain hose kinked or low
- 2Filter and pump packed with debris
- 3Disposal knockout plug left in place
- 4Drain pump impeller jammed
Step-by-Step Troubleshooting
- 1
Follow the drain hose from the Thermador cabinet to the disposal or standpipe and remove any kink or sag that traps water
- 2
On a freshly installed unit, confirm the garbage-disposal knockout plug was punched out, the single most common cause of a first-run drain fault
- 3
Pull the filter and reach into the drain-pump throat to clear glass fragments, seeds, or a stray label that stalls the impeller
- 4
Verify the hose rises into a high loop or air gap so sink water cannot siphon back into the tub
Pro Diagnostic Tip
Thermador drain pumps are intolerant of small hard debris — a single sliver of broken glass in the impeller reproduces E24 after every drain. Inspect and clear the impeller chamber fully before assuming the pump motor has failed.
