Error Code: 3-2 Difficulty: Moderate
Problem: Shorted temperature sensing circuit.
How to Fix 3-2 Error (Step-by-Step)
- Disconnect Power: Turn off the power to the dishwasher at your home’s circuit breaker.
- Access the Sump Area: Remove the bottom dish rack. You may need to remove the lower spray arm and filter assembly to access the temperature sensor. The spray arm usually lifts off or is held by a central nut.
- Locate the Sensor: The temperature sensor (also part of the OWI assembly) is a small plastic component located in the sump area at the bottom of the dishwasher tub. It will have a wire harness connected to it.
- Remove the Old Sensor: From underneath the dishwasher, you may need to remove the lower access panel (kickplate). Locate the sensor from below, twist it (usually a quarter-turn counter-clockwise), and pull it out. Disconnect the wire harness.
- Install the New Sensor: Connect the wire harness to the new sensor. From inside the tub, insert the new sensor into the sump opening, ensuring the rubber gasket is properly seated. Twist it clockwise to lock it into place.
- Reassemble and Test: Reinstall the filter and spray arm inside the dishwasher, and reattach the lower access panel. Restore power and run a cycle to confirm the fix.
- 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.
