What does ITW Food Equipment Group 18 mean?
The booster took longer than its allowed time to fill, so the control flagged a fill error. The booster supplies the final rinse, and this error usually points to a pinched or kinked supply hose or an interrupted water supply preventing the booster from filling to its setpoint in time.
Symptoms
- Error code 18 shown on the display
- Booster slow to fill or not filling
- Final rinse delayed or not delivered
- Cycle stalls waiting for the booster
Common causes
- Supply hose pinched or kinked
- No or low water being supplied to the machine
- Restricted fill path to the booster
- Fill valve malfunction

Diagnostic steps
Check the supply hose
Verify the supply hose is not pinched or kinked.
Confirm water supply
Check that water is being supplied to the machine and that any shutoff is open.
Let the booster fill
Once water fills the booster to setpoint within the set time, the error will clear on its own.
Call Hobart Service if it persists
If the error continues to display, a fill valve malfunction is possible; contact Hobart Service at 1-888-4HOBART.
When to call a professional
Contact Hobart Service if code 18 persists after confirming the supply hose is clear and water is reaching the machine. A booster that still will not fill in time may have a fill valve malfunction, which an authorized Hobart technician should test and replace. Correct booster filling is essential for the sanitizing final rinse, so resolve this before relying on the machine.
