Amana Dishwasher Error 3-3

How to Fix 3-3 Error (Step-by-Step) Cut Power to Dishwasher: Go to the main circuit breaker in your home and switch off the power supply to the dishwasher. Access the Sensor: Remove the lower dish rack to get clear access to the bottom of the dishwasher tub. The OWI (Optical Water Indicator) sensor is located in the sump area. Remove Filter and Spray Arm: Take out the dishwasher’s filter assembly and the lower spray arm. This will expose the sensor for removal. Disconnect and Remove Sensor: The sensor is typically held in place by a locking tab. From underneath the dishwasher (you may need to remove the front kickplate), locate the sensor, turn it counter-clockwise to unlock it, and pull it out of the sump. Disconnect its wire harness. Install New OWI Sensor: Attach the wire harness to the new sensor. Insert the new sensor into the sump opening from inside the tub, making sure the seal is snug. Turn it clockwise to lock it into position. Reassemble and Power Up: Reinstall the filter assembly and the lower spray arm. Put the lower dish rack back in place. Restore power at the circuit breaker and run a check or wash cycle to allow the new sensor to calibrate. 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.
