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
The fault line and the age of the housing
The Hayward Fault runs directly beneath Richmond through to Fremont, seismic gas valves are common here, and a fifth of the stock predates 1940 — both change what a symptom actually means.
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
EBMUD's Mokelumne supply runs 1 to 7 grains per gallon — soft to moderate, and well below the Contra Costa side of the tunnel. Scale is seldom the explanation here, which usually points the diagnosis at the valve, the filter or the line rather than at mineral.
