Thermador Dishwasher Won't Heat Water
Dishwasher Won't Heat Water 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 supply whose chemistry moves through the year
Sources here are blended seasonally, so an element scaled to one blend meets another and a descaling interval that held for a year stops holding.
A failed bake or broil element
The most common cause of a full loss of heat in an electric oven.
A drifted temperature sensor
Electronic sensors drift out of spec gradually, so the oven can run well off-target without any error showing.
Local conditions that matter here
The supply here changes chemistry through the year as sources are blended, so what is coming out of a fill line in March is not what was coming out in September. An appliance calibrated to one blend meets another, which is why descaling intervals that held for a year stop holding.
