TLDR

On your AM16 DISHWASHERS unit, error code 023 signifies a failure to reach the wash tank's required water level within the maximum fill time. This typically points to issues with the incoming water supply, inadequate water pressure, or a malfunctioning fill valve. Always begin by verifying the water connections and supply pressure before checking internal components.

Technical Details

Repair Steps:

  1. Verify Incoming Water Supply: Ensure the main water supply valve to the dishwasher is fully open. Check that the fill hose connecting to the unit is not kinked, crushed, or obstructed.
  2. Check Water Pressure: Use a pressure gauge to verify that the incoming water pressure is within the specified range of 15-65 psi (100-450 kPa). Low water pressure will prevent the tank from filling adequately within the timed cycle.
  3. Inspect the Fill Valve: Access the fill valve and inspect it for any visible blockages, debris, or mechanical issues preventing it from opening fully. Check the electrical connections to the solenoid for power during a fill cycle; if it’s not energizing or is stuck, the valve may need cleaning or replacement.
  4. Examine Water Level Sensor/Switch: Although the error specifically mentions fill time, a faulty water level sensor or float switch could incorrectly indicate that the tank is not full, even if it is. Inspect its operation and ensure it’s not fouled by scale or debris.
  5. Clear Error and Test: Press the ENTER button on the control panel to clear the error. Initiate a wash cycle to observe if the unit fills correctly. If the error persists after these checks, it indicates a more complex issue with the fill system or control board, requiring professional Hobart Service.

Common Questions:

Q: What does error code 023 specifically indicate on a HOBART AM16 DISHWASHERS?

A: Error code 023 on your HOBART AM16 DISHWASHERS indicates that the fill valve has been active for too long without the wash tank reaching its required water level, implying a problem with water delivery or level detection.

Q: How can I quickly check if low water pressure is causing this error?

A: You can use a water pressure gauge at the inlet connection point to confirm the pressure is within the 15-65 psi operating range. Visually, observe the flow rate from a nearby faucet; a noticeably weak flow might suggest a supply issue.

Q: Is it possible for the fill valve to be stuck closed or partially open?

A: Yes, the fill valve can become stuck closed or partially open due to mineral deposits, debris, or a faulty solenoid. This prevents adequate water flow into the wash tank and can trigger error 023.

When to call a technician

For this error, we recommend calling a certified technician. Do not continue operation or attempt repair yourself.

  • Equipment shows a critical or stop-operation fault.
  • You smell gas, burning, or see smoke or sparks.
  • Error returns after following the steps above.
  • You are not trained to work on this equipment.
  • Warranty or safety could be affected by DIY repair.
