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 age of the installation rather than the appliance
This is the oldest housing stock of any metro we cover, and in a pre-1940 kitchen the opening, the venting and the supply are usually older than the fault being reported.
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
Hetch Hetchy water arrives at 1 to 3 grains per gallon, among the softest supplies in the country, so scale is rarely the answer in this city. Soft, low-alkalinity water lays down no protective film and slowly strips the one that is there, which is why failures here show up as pitting and weeping joints on copper fill lines rather than as a furred-up valve.
