My dishwasher shows E22 or E24 and won't drain. Is that a big repair?

Not usually — those are Thermador's documented drainage-error codes, and the first checks are the filter, the drain pump cover, and the drain hose for kinks or blockage. If cleaning those doesn't clear it, the drain pump itself needs a look.

I see an E12 or E2060 limescale code. What should I do?

Run a proper descaler through a cycle and add water-softening salt if your unit uses it — Thermador's own documentation lists limescale build-up in the heat pump as the specific cause of these two codes.

E15 or E3100 appeared and there's water in the bottom of my dishwasher. Is it safe to keep running it?

No — Thermador's own guidance for this code is to turn off the water supply and contact support. That code means a safety switch has detected water where it shouldn't be, and running another cycle risks a bigger leak.

Dishwasher Repair, Done Right the First Time

A Thermador dishwasher that won't drain, won't fill, or displays one of its many documented E-codes almost always traces back to one of a specific set of parts — the drain pump, flow meter, heat pump, or a water-safety switch — not a reason to assume the whole unit has failed.

Thermador’s dishwashers publish one of the most detailed documented error code lists of any category on their support site — drainage problems (E22/E23/E24/E25/E6101-E6103/E9240) covering the filter, drain pump, and hose; water-inlet problems (E14/E16/E17/E18/E3000/E3200/E3300/E3400) covering the flow meter and inlet hose; limescale problems (E12/E2060) in the heat pump; and a dedicated safety-switch code (E15/E3100) for water detected in the unit’s base.

Because Thermador documents so many of these codes with a specific real cause, we start from the code itself rather than a generic “dishwasher not working” diagnosis — checking the filter and drain pump for drainage codes, the inlet hose for water-flow codes, and treating any base-water safety code as a reason to shut off the water supply until it’s inspected.
