Whirlpool Dishwasher Error Code F03

For most homeowners, their dishwasher is without a doubt one of their favourite and most convenient kitchen appliances. Serving the purpose of clearing the kitchen worktops to be free from dirty dishes after those large family dinners.

Not to mention that it means that the dreaded question of "who's doing the dishes tonight?" does not need to be asked after you have enjoyed your meals.

If your dishwasher is displaying an F03 error code during the wash cycle, it’s an indication that there's a problem with the water heating up - and the likely offender would either be the element or flow through heater.

Your plates, dishes, and cutlery could still have a build-up of grease on them if the appropriate water temperature is not achieved, and the wash cycle may not finish correctly.

Cause 1

Element

A dishwasher heats the water by using an element in the bottom of the tub, or a flow through heater which can be found at the base of the machine.

Checking the element using a multimeter will give you a clearer diagnosis and will help you to confirm if the fault does originate from a defective element or not.

A multimeter is a device which helps test the electrical resistance of an element. To help understand the purpose of a multimeter, and how exactly to use one, you can see our helpful multimeter guide.

Safety First! Please ensure that you have disconnected the appliance from the mains before starting any repair.

  • Once accessed, place the probes across the element’s terminals.
  • Once they are touching the multimeter should show a reading of 20 to 30 ohms.
  • If the reading is far higher or shows no movement, then the element has likely failed.

If after performing this test you find that you need to replace the element or flow through heater, you can see our handy guide to show you how to do this in our easy step by step guide here:
