Thermador Dishwasher Won't Drain
Dishwasher Won't Drain 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
A machine that sat full of standing water
A sump left wet for a season grows biofilm that no normal cycle clears, and the smell and poor rinse that follow read as a pump fault.
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.
Local conditions that matter here
An unoccupied house also means still water sitting in fill lines and ice moulds for months. Lines that sit stagnant foul faster than lines in daily use, which is why seasonal properties here need a different maintenance interval from year-round ones.
