ITW Food Equipment Group 08 Error Code
Booster pressure level sensor voltage below lower 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 08 mean?
The booster pressure (water level) sensor is reporting a voltage below its allowed lower limit, so the control cannot trust its booster level reading. Cycling power to begin draining and then refilling the tank lets the pressure level sensors reset, which often clears the fault.
Symptoms
- Error code 08 shown on the display
- Booster water level reading appears incorrect
- Machine will not progress through fill or rinse
- Error persists until the sensor resets
Common causes
- Booster pressure level sensor out of calibration or faulty
- Loss of water or pressure at the sensor
- 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 booster level reading and code 08 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 08 stays on after draining and refilling to reset the pressure level sensors. A sensor reading below range may be faulty, disconnected or affected by a plumbing issue. An authorized Hobart technician should test the booster pressure level sensor and its wiring and replace it correctly so the booster water level is measured reliably.
