How to Reset a Thermador Dishwasher and Clear Error Codes

Quick Answer

There are two ways to reset a Thermador dishwasher. A soft reset - pressing and holding Start/Stop for 3-5 seconds - cancels the current program and clears most error codes once the underlying fault is fixed. A hard reset - unplugging from the wall for 60 seconds - performs a full power cycle that clears the control board memory. Neither reset method will clear E15 (AquaStop) - that code requires physically draining the base pan before the machine will operate again. To read stored fault codes before resetting, hold the Start button for 5 seconds to enter diagnostic mode.

Frequently Asked Questions

How do I reset a Thermador dishwasher?

Press and hold Start/Stop for 3-5 seconds to cancel the current program (soft reset). For a full reset, unplug the dishwasher from the wall for 60 seconds, then plug back in. The exception is E15 - that requires draining the base pan physically before the machine will clear the code.

Why does the error code come back immediately after I reset?

A reset only clears the stored code - it does not fix the underlying problem. If the fault condition is still present (clogged filter, water in base pan, failed component), the machine will detect it again in the next cycle and re-trigger the same code.

How do I enter diagnostic mode on a Thermador dishwasher?

Hold the Start button for 5 seconds. The display will cycle through any fault codes stored in memory. Read the codes first before resetting, so you know what problem to investigate.

Is there a factory reset option on Thermador dishwashers?

No dedicated factory reset function exists. A 60-second unplug cycle (hard reset) clears the control board memory and is the equivalent of a factory reset for fault clearing purposes.

My Thermador dishwasher buttons are unresponsive. How do I reset it?

Unresponsive buttons often indicate child lock is activated. Try pressing and holding the program button or the Start button for 5 seconds to exit child lock. If that does not work, unplug for 60 seconds to perform a hard reset.
