Hobart dishwasher overflows or water comes out of the door or vent during fill or wash.

Safety first: Turn off power and close the water supply immediately if overflow occurs.

• Clear level tube: Locate the pressure tube from the tank to the level switch. Remove and blow through it to clear any blockage. Clean the tank connection.
• Inspect inlet valve: With power off and water supply closed, remove the inlet valve and check for debris preventing full closure. Replace if it leaks when de-energized.
• Test level switch: If qualified, test the level switch for proper operation with a multimeter while applying pressure. Replace if it does not change state.
• Monitor after repair: Restore power and water, then run a fill while watching the level. If overfill persists, the control board may be faulty and require service.
