What does ITW Food Equipment Group 05 mean?
The wash tank water temperature has risen above its allowed upper limit. The control monitors the main wash tank and trips this error when it reads too hot, which usually indicates a tripped high-limit thermostat or a wash tank heating element that is not switching off properly.
Symptoms

- Wash water hotter than normal
- Machine stops or will not complete a cycle
- Error returns after a restart
Common causes
- High-limit thermostat tripped on the wash tank
- Wash tank heating element malfunction (stuck on)
- Wash tank temperature sensor reading out of range
- Control fault in the wash tank heat circuit

Diagnostic steps
Power the machine off
Press the power button to switch the dishwasher off and allow roughly 20 minutes for the wash tank to cool down.
Restart as normal
Press the power button again to restart the machine as you normally would.
Check the wash temperature
Run a cycle and confirm whether code 05 clears once the wash tank reaches operating temperature.
Call Hobart Service if it persists
If the error continues to display, the likely cause is a high-limit trip or heating element malfunction; contact Hobart Service at 1-888-4HOBART.
When to call a professional
Contact Hobart Service if code 05 persists after a power-off, cool-down and restart. A wash tank running over temperature usually means a tripped high limit or a heating element that will not shut off, both in the line-voltage heating circuit. An authorized Hobart technician should test the high-limit thermostat, element and sensor before returning the machine to service.
