ITW Food Equipment Group 09 Error Code
Wash tank pressure level sensor voltage above upper limit
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 09 mean?
The wash tank pressure (water level) sensor is reporting a voltage above its allowed upper limit, so the control cannot trust its reading of the wash tank water level. Cycling power to start draining and then refilling the tank lets the pressure level sensors reset, which often clears the error.
Symptoms
- Error code 09 shown on the display
- Wash tank water level reading appears incorrect
- Machine will not fill or progress through a cycle
- Error persists until the sensor resets
Common causes
- Wash tank pressure level sensor out of calibration or faulty
- Trapped pressure or air affecting the sensor reading
- Wiring or connection fault at the pressure sensor
- Control fault reading the sensor voltage

Diagnostic steps
Power off then on
Press the power button off then on to start the draining process.
Drain and refill
Let the machine drain the tank and refill, which should reset the pressure level sensors.
Confirm the sensor reads correctly
Run a cycle and check whether the wash tank level reading and code 09 have cleared.
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 09 remains after draining and refilling to reset the pressure level sensors. A wash tank level sensor that keeps reading out of range may be faulty, miswired or affected by a plumbing problem. An authorized Hobart technician should test the sensor and its circuit and replace it so the wash tank level is read accurately.
