ITW Food Equipment Group 03 Error Code
Rinse assurance – booster did not meet temperature or water level requirements
Source: ITW FOOD EQUIPMENT GROUP/00008 EDH-EDL_EUH-EUL Dishwashers Operation and Error Card F48737 (01-23).pdf
What does ITW Food Equipment Group 03 mean?
Rinse assurance has detected that the booster did not reach its required temperature or water level before the final rinse. To protect wash results, the machine triggers an extended wash cycle of 10 to 20 minutes so the booster has time to recover before the rinse is delivered.
Symptoms
- Error code 03 shown on the display
- Wash cycle runs unusually long (10 to 20 minutes)
- Booster slow to reach temperature or fill
- Code reappears on the next cycle if the booster still falls short
Common causes
- Booster not reaching its temperature setpoint
- Booster not reaching its water level setpoint
- High-limit thermostat tripped on the booster
- Booster heating element malfunction

Diagnostic steps
Let the long wash cycle run
When the booster has not met its temperature or water level setpoint, a long wash cycle of 10 to 20 minutes is triggered automatically; allow it to complete.
Confirm the booster recovers
Check that the booster reaches its temperature and fill setpoints during the extended cycle.
Watch the next cycle
Run the following cycle and see whether code 03 continues to display.
Call Hobart Service if it persists
If the error continues to display on the next cycle, a high-limit trip or heating element malfunction is likely; contact Hobart Service at 1-888-4HOBART.
When to call a professional
Call Hobart Service if code 03 returns on the next cycle after the extended wash has run. A booster that repeatedly fails to meet temperature or water level points to a tripped high limit or a heating element fault in the line-voltage circuit. An authorized Hobart technician should diagnose the booster heating and fill system to restore proper rinse assurance.
