Thermador Dishwasher Control Fault
Dishwasher Control Fault is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Eichler construction rather than the appliance
The Peninsula holds more Eichlers than anywhere — 2,700 in Palo Alto alone — and radiant slab, no attic and no crawlspace change how almost every repair has to be done.
A specific failed component rather than the whole unit
Most single-symptom issues trace back to one part, not a systemic failure.
Wear on parts that see the most daily use
Moving parts and seals typically fail before electronic or structural components.
Local conditions that matter here
In an Eichler a new water line cannot go under the floor, because there is no floor to go under — the slab carries the radiant heating loop, and cutting it turns a kitchen job into a heating job. Lines here run overhead or around the perimeter, which is why the same repair takes longer on one street than on the next.
