Thermador E4 error code

The grinder is jammed, often by a stone or foreign object in the beans — we clear and test it.

Because a code points to a likely area rather than an exact part, we run a full on-site diagnosis to confirm the real cause — testing the components above and the wiring and controls behind them. You get a clear, flat-rate quote before any work begins, and most E4 faults are resolved on the first visit with quality parts and a parts-and-labor warranty.
