Why your Thermador dishwasher is not heating
On a Thermador dishwasher, not heating usually announces itself like this: appliance runs but doesn't reach set temperature. Failed heating element, igniter, or thermal fuse. Nine times out of ten it comes down to burned-out heating element. Left unaddressed, laundry backs up fast.
Most likely causes
- Failed igniter or gas valve
- A bad control board
- Faulty temperature sensor
- Tripped thermal fuse
Known Thermador dishwasher weak points
- Freedom Induction coil-driver board faults (zones drop out)
- Column refrigerator door alarm / reed-switch failure
- Steam oven scaling from hard water
- Star Burner igniter and control faults
Quick check — and when it's not DIY
The one self-check that's actually worth your time: confirm the dishwasher has power, any gas supply valve is open, and a simple reset — power off 60 seconds, back on — doesn't restore heat. Should that not clear it, no spark or flame usually means the igniter or gas valve itself has failed, and gas-carrying parts are restricted to licensed work in most jurisdictions.
