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
Which water reaches your block
Groundwater at 11 to 26 grains per gallon and imported Sierra water at 4.5 to 9 arrive through the same utility, so identical appliances five miles apart fail differently.
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
This is the local fact that matters most for anything plumbed. Groundwater at 11 to 26 grains per gallon is harder than Las Vegas; the imported blend at 4.5 to 9 is not. Two houses a few streets apart get genuinely different water, so a descaling interval that works at one address is wrong at the other, and a softener sized for a previous house is usually wrong at this one.
