Published 2025-05-27 · Error & Fault Codes
A Thermador E24 code means the dishwasher cannot drain, so water sits in the tub at the end of the cycle. The fault lives in the drain path rather than the wash system. A clogged filter, a kinked or blocked drain hose, or a tired drain pump accounts for the large majority of E24 cases.
What We Check
Reading the sign is the start; testing confirms the part. Here is how we work this fault on Thermador:
| Code | What It Means | What We Check |
|---|---|---|
E22 | Filter or circulation restriction | Clean the filter and check the spray arms |
E09 | Heating-element fault | Test the flow-through heater and its wiring |
How We Fix It
- A drainage error stopping the cycle
- Oven temperature drifting from the set point
Other Thermador codes we read on Thermador include E15 and E24. See the full list and model lines on our Thermador repair page.
Why It Matters
Standing water and leak codes are worth a prompt look, especially in homes with finished lower levels. We trace the real source, correct it, and confirm the machine drains fully before we leave.
