ITW Food Equipment Group 22 Error Code

What does ITW Food Equipment Group 22 mean?

The rinse temperature has measured below its setpoint on three consecutive cycles, so the machine flags a low rinse temperature error. Because the final rinse is responsible for sanitizing, the control monitors it closely; the error clears automatically once the rinse meets or exceeds its setpoint again.

Symptoms

• Error code 22 shown on the display
• Rinse water cooler than required
• Low rinse temperature over three consecutive cycles
• Sanitizing performance in doubt

Common causes

• Booster not reaching rinse temperature setpoint
• High-limit thermostat tripped on the booster
• Booster heating element malfunction
• Booster temperature sensor reading low

Diagnostic steps

1. Understand the trigger

   Code 22 sets when rinse temperature is below setpoint on three consecutive cycles.

2. Let the rinse recover

   The error will clear if the rinse temperature meets or exceeds its setpoint on a following cycle.

3. Run further cycles

   Run additional cycles and watch whether code 22 clears as the booster reaches temperature.

4. Call Hobart Service if it persists

   If the error continues to display, contact Hobart Service at 1-888-4HOBART.

When to call a professional

Contact Hobart Service if code 22 continues to display and the rinse will not reach its setpoint. A persistently low rinse temperature usually means the booster is not heating, which can stem from a tripped high limit or a heating element fault in the line-voltage circuit. Sanitizing depends on the rinse, so an authorized Hobart technician should restore proper booster temperature before relying on the machine.
