JennAir 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
Detergent dosed for hard water
Soft water needs far less of it, and the film and poor-rinse complaints that follow over-dosing look exactly like a failing wash pump.
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
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.
