On your HOBART LXn/LXGn SERIES DISHWASHERS unit, Error Code 022 indicates that the wash water level is not being maintained at its normal operating level, most commonly due to a clogged or kinked drain hose.

Technical Details

Repair Steps:

  1. Safety First: Power Off and Cool Down: Before beginning any inspection or maintenance, immediately turn off the main power supply to the HOBART LXn/LXGn dishwasher at the circuit breaker or disconnect switch. Allow the wash water to cool completely to a safe handling temperature to prevent burns.
  2. Inspect Wash Tank for Debris: Open the dishwasher door and carefully remove the wash arms and filters. Visually inspect the bottom of the wash tank for any food particles, glass fragments, or other debris that might be obstructing the drain or interfering with water level sensors. Clean out any foreign material found.
  3. Clean the Drain Hose: Locate the drain hose, typically connected from the bottom of the wash tank to your facility’s drain system. Disconnect the hose at both ends if possible. Thoroughly flush the drain hose with water to clear any internal clogs or buildup. Use a snake brush if necessary for stubborn blockages.
  4. Check Drain Hose Installation and Kinks: While the drain hose is accessible, inspect its entire length for any kinks, sharp bends, or damage that could restrict water flow. Ensure the hose is routed properly, without excessive sagging or uphill sections that could trap water. Reinstall the hose, ensuring secure connections.
  5. Verify Drain System Integrity: Confirm that the facility’s drain connection point itself is clear and not obstructed. Sometimes, the issue might lie in the building’s plumbing rather than the dishwasher’s internal components.
  6. Clear Error and Test Operation: Once all inspections and cleaning steps are completed, restore power to the dishwasher. If Error Code 022 persists, press the ENTER button on the control panel to attempt to clear the error. Initiate a wash cycle and monitor the water level carefully to ensure it is maintained correctly. If the error reoccurs, further investigation by a qualified technician may be required to check water level sensors, drain pump, or control board.
