Thermador Dishwasher Won't Start
Dishwasher Won't Start 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
Incoming water already warm
Supply temperature in summer is far above the design assumption, which changes cycle timing and how detergent behaves.
A clogged filter or drain line
The single most common cause of drainage and cleaning-performance complaints.
A failed door latch or control fault
Many dishwashers won't start at all if the door sensor doesn't register a full, secure close.
