Why your Thermador dishwasher is not heating
A Thermador dishwasher that is not heating tends to show the same signs: appliance runs but doesn't reach set temperature. Failed heating element, igniter, or thermal fuse. More often than not it traces back to failed igniter or gas valve. Left unaddressed, laundry backs up fast.
Most likely causes
- Faulty temperature sensor
- Tripped thermal fuse
- A bad control board
- Failed igniter or gas valve
- Burned-out heating element

Quick check — and when it's not DIY
One thing you can rule out on your own: check whether an ignition click or spark is audible at all when it should be heating. Also, 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. Once you've ruled that out, 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.
