Hotpoint FDL Series Dishwasher Error Code F04
A dishwasher is no doubt a great help for many homes, as after those large family dinners nobody wants to wash the dishes, do they!
Unfortunately however over time, like other appliances, the dishwasher can suffer from a variety of faults.
When the water is refusing to heat up during your dishwasher washing cycle, and it displays an error code F04 (the last light from the left), you may have a fault with either your element or flow through heater.
Without the desired water temperature your plates, dishes, and cutlery could still have a build-up of grease and remnants of your previous meal on them - and the cycle will not complete correctly.
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.
However, if your dishwasher isn't heating up properly, the most likely explanation is a faulty heating element that needs to be replaced. That being said, it's always a good idea to check and make sure a part is faulty before replacing it. Fortunately, we have a step-by-step guide demonstrating how to test the heater in a dishwasher with a multimeter right here.
If, after performing this test, you find that you need to replace the element or flow through heater, you can follow our handy step-by-step guide showing you how to do this here:
