Error Code: F03 Difficulty: Hard
Problem: Water drain failure/timeout. The dishwasher is not draining water correctly.
How to Fix F03 Error (Step-by-Step)
- Disconnect the dishwasher from power and water supplies. Turn off the circuit breaker and shut off the water valve under the sink.
- Place towels under the dishwasher to catch any residual water. Carefully pull the dishwasher out from under the counter.
- Locate the drain pump at the bottom of the dishwasher. It will have the drain hose connected to it.
- Disconnect the electrical connector and the hoses from the old drain pump. Be prepared for some water to spill out.
- Remove the screws or clips holding the old pump in place and remove it from the dishwasher.
- Install the new drain pump (W10518394), making sure to securely fasten it and reconnect the hoses and electrical connector.
- Slide the dishwasher back into place, reconnect the power and water, and run a test cycle to ensure it drains properly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
What to Check Next on This Amana Dishwasher
Focused repair path: dishwasher fill, drain, wash motor, heating, leak, sensor, and control checks. Do not treat a returning fault as a reset-only problem; use the point in the cycle where the fault appears to choose the next check.
- Disconnect power before opening panels, then confirm the door latch, float, inlet valve, drain path, and harness connections are seated.
- Match the timing of the failure to the likely path: fill, wash circulation, drain, heat, leak detection, or control communication.
- Clear debris from filters, sump areas, spray arms, and the drain loop before treating the fault as a failed board.
- If a part is suspected, verify voltage or continuity where appropriate and match the complete Amana dishwasher model number before ordering.
Check, inspect, clean, test, measure, remove, reconnect, clear, and replace parts only when the symptom supports that path. If these checks point toward a part, verify the complete Amana model number from the appliance tag before ordering. Similar error wording can use different valves, sensors, pumps, motors, heaters, locks, switches, fans, or control boards depending on the exact model.
