What does ITW Food Equipment Group 30 mean?
At startup, the booster took longer than allowed to heat up to temperature, so the control flagged a booster heat up time exceeded error. This usually points to a tripped high-limit thermostat or a heating element malfunction preventing the booster from reaching its setpoint in the expected time.
Symptoms
- Error code 30 shown on the display at startup
- Booster slow to reach temperature
- Final rinse not ready when expected
- Error returns after a restart
Common causes
- Booster heating element malfunction
- High-limit thermostat tripped on the booster
- Power interruption to the booster heat circuit
- Booster temperature sensor fault

Diagnostic steps
Power off and drain
Press the power button to power off the machine and drain the tank.
Restart as normal
Press the power button to restart the machine as you normally would.
Cycle the power supply
If the error continues, unplug the machine from the wall; if it is hardwired, turn the circuit breaker off then back on.
Call Hobart Service if it persists
If the error continues to display, a tripped high limit or heating element malfunction is possible; contact Hobart Service at 1-888-4HOBART.
When to call a professional
Contact Hobart Service if code 30 persists after restarting and cycling power at the wall or breaker. A booster that will not heat up in time usually means a tripped high limit or a heating element malfunction in the line-voltage circuit. An authorized Hobart technician should test and replace these parts so the booster reaches sanitizing temperature within its allowed startup time.
