Error Code: 9-1 Difficulty: Hard
Problem: Faulty Control Motor Drive Circuit or Sense Circuit.
How to Fix 9-1 Error (Step-by-Step)
- Disconnect Power Source: Ensure your safety by turning off the circuit breaker that supplies power to the dishwasher.
- Access the Control Board: Remove the screws holding the inner door panel in place. This will give you access to the dishwasher’s electronic components.
- Identify the Board: Locate the main control board (Part No. WPW10285180 or W11413274). It is the central hub for all the wiring.
- Photograph and Disconnect: Before disconnecting anything, take a clear picture of the wire layout. Then, carefully unplug all the wire harnesses from the board.
- Replace the Board: Release any clips or screws holding the old board and remove it. Snap or screw the new control board into the same location.
- Reconnect and Reassemble: Following your reference photo, reconnect all the wire harnesses to the new board. Secure the inner door panel back onto the dishwasher.
- Power Up: Turn the circuit breaker back on and start a new cycle to verify that the dishwasher is functioning correctly.
- 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.
