Understanding F3: Thermistor Fault – Simultaneous Flashing of Heavy and Delicate Lights

Has your Maytag dishwasher suddenly started acting up and showing the error code F3? Don’t fret! In this article, we’ll dive into the details of this common error and guide you on how to fix it like a pro. Let’s get started!

What is the F3 error code on a Maytag dishwasher?

The F3 error code on a Maytag dishwasher indicates a thermistor fault, which is a problem with the temperature-sensing device in your dishwasher. This fault occurs when the heavy and delicate lights start flashing simultaneously, leaving you scratching your head wondering what went wrong.

How to Fix the F3 Error Code

Now, let’s roll up our sleeves and fix this thermistor fault in a jiffy:

  1. Check the wiring connections: Start by turning off the dishwasher and unplugging it from the power source. Carefully inspect the wiring connections on the thermistor, looking for any loose or damaged wires. Reinstate any loose connections and replace any damaged wiring.
  2. Test the thermistor: Using a multimeter, you can test the resistance of the thermistor to determine its functionality. Consult your dishwasher’s user manual or the manufacturer’s specifications to find the required resistance range for the thermistor. If the readings are outside the optimal range, the thermistor may need to be replaced.
  3. Replace the thermistor: If the thermistor fails the resistance test, it’s time to replace it. Locate the thermistor in your dishwasher, often found near the water inlet valve or the heating element, and carefully remove it. Make note of the part number and order a replacement from an authorized Maytag retailer. Once you have the new thermistor, simply install it in the same location and reconnect any wiring.
  4. Reset the dishwasher: After completing the replacement, plug your dishwasher back in and turn it on. Ensure that the error code F3 no longer appears. If it doesn’t, you can breathe a sigh of relief as you have successfully resolved the thermistor fault.

Remember, if you are uncomfortable performing any of the steps mentioned above, it’s always best to seek professional help or contact Maytag’s customer support for further assistance.
