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
A drying cycle fighting the air
Low humidity helps evaporation but the lower boiling point works against the heated rinse, and poor drying here is often elevation rather than the element.
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
Boiling point here is closer to 202°F than 212°F, which changes how anything that steams or boils behaves. A steam cycle that never seems to finish is often altitude rather than fault.
