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
Hardness a coastal routine would ignore
A descaling interval that works in Oakland at 1 to 7 grains per gallon is wrong here at 7.2, and the resulting film reads as a failing wash system.
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
Contra Costa Water District delivers around 7.2 grains per gallon in Concord, the hardest supply in the Bay Area network and several times EBMUD's 1 to 7 on the other side of the hills. A descaling routine a coastal kitchen can skip is not optional out here.
