Thermador Dishwasher Leaking Aquastop
Dishwasher Leaking Aquastop 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 valve held open by deposit
Hard groundwater leaves mineral on the seat, and a valve that no longer closes fully weeps continuously rather than failing outright.
A clogged defrost drain
Melted frost backs up and overflows into the cabinet or onto the floor instead of draining away normally.
A worn or torn door gasket
Lets humid air in that condenses inside the cabinet or around the door frame.
Local conditions that matter here
This is the local fact that matters most for anything plumbed. Groundwater at 11 to 26 grains per gallon is harder than Las Vegas; the imported blend at 4.5 to 9 is not. Two houses a few streets apart get genuinely different water, so a descaling interval that works at one address is wrong at the other, and a softener sized for a previous house is usually wrong at this one.
