Diagnostic steps
Power off the machine
Press the power button to power off the machine after the system reports it exceeded maximum fill time.
Check the supply hose
Verify the supply hose is not pinched or kinked.
Confirm water supply, then restart
Check that water is being supplied to the machine, then restart as normal.
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 31 persists after confirming the supply hose is clear and water is reaching the machine. A system that still exceeds maximum fill time may have a fill valve malfunction, which an authorized Hobart technician should test and replace. Proper filling is required before the wash and sanitizing rinse can run correctly.
