Commercial Dishwasher Not Heating in St. Augustine, FL

Why your commercial dishwasher is not heating
Not heating on a commercial dishwasher usually announces itself like this: appliance runs but doesn't reach set temperature. Failed heating element, igniter, or thermal fuse. The symptom can be consistent with a bad control board. Left unaddressed, laundry backs up fast.
Most likely causes
- Faulty temperature sensor
- Burned-out heating element
- A broken door switch cutting the heat circuit
- Tripped thermal fuse
Quick check — and when it's not DIY
Before you call anyone, confirm the commercial dishwasher has power, any gas supply valve is open, and a simple reset — power off 60 seconds, back on — doesn't restore heat. Also, check whether an ignition click or spark is audible at all when it should be heating. Beyond that, 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.
How we fix it
First we diagnose the commercial dishwasher end to end, so you're not paying to swap parts on a guess. The technician confirms which part fits the model and whether it is available after diagnosing the fault. The repair options, price, and expected timing are confirmed after diagnosis.
