The answer you came for

How to fix Amana dishwasher error 6-6

Start with the safest checks and work from simple to technical.

  1. 1

    Step 1

    1. Before starting a dishwasher cycle, run the hot water at the kitchen sink faucet for a minute or two until the water is hot to the touch.

  2. 2

    Step 2

    2. This purges the cold water from the hot water line, ensuring that your dishwasher starts its cycle with hot water immediately.

  3. 3

    Step 3

    3. Check the temperature setting on your home's water heater. For best dishwasher performance, it should be set to at least 120°F (49°C).

  4. 4

    Step 4

    4. Avoid running other hot water appliances, like a washing machine or shower, at the same time as the dishwasher to ensure an adequate supply of hot water.

  5. 5

    Step 5

    5. If your dishwasher has a 'High-Temp Wash' or 'Sani-Rinse' option, select it. This uses the dishwasher's internal heater to boost the water temperature to the required level.

  6. 6

    Step 6

    6. If the problem continues, the dishwasher's internal water heater or thermostat may be malfunctioning, which would require a more technical repair.

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.

What may be causing it?

  • Water supply temperature is too low
  • Dirty or faulty Optical Water Indicator (OWI) sensor
