Miele dishwasher error code F24

The number of errors in modern smart dishwashers is staggering. A common error message, F24, appears on the dishwasher's display, informing the user that the water is not heating. This is usually caused by a faulty heating element, but the problem can also be caused by a lack of signal between the heating element and the control board, a burnt-out starting capacitor, or damage to other components. Let's look at how to fix the problem.

What elements will need to be checked?

The most common cause of the F24 error code in a Miele dishwasher is the heating element activation relay. This relay is located on the dishwasher's control module. It receives a signal from the thermostat and activates the heating element, which then heats the water for the cycle. How can I determine if the relay is faulty?

• Error F24 is not displayed immediately, but a couple of minutes after the water has been collected.
• When an error code appears, after a few seconds the Miele dishwasher pump will begin to pump out all the liquid.

If all the symptoms match, the damaged relay needs to be replaced, which requires removing the dishwasher's control module. What can I do to reset the fault and restore the functionality of my "home assistant"?

• Carefully disassemble the door of the Miele dishwasher.
• Disconnect the wiring from the control module.

Be sure to take a photo of the wiring so that you can reconnect all the wires without errors during reassembly.

• Remove the control board.
• Replace the relay.
• Install the element and assemble the door.

The problem may be that the original relay typically costs around $80. You can buy a replacement, but it may not fit your Miele dishwasher, or it may simply not work properly, so it's best not to risk it for the sake of saving money.

Also, do not rush to eliminate the cause of the malfunction until you are sure that the relay is actually faulty. First, it's worth checking it with a regular multimeter, as the problem may be the lack of a signal between the thermostat and the dishwasher's control board. Check all sections of the circuit, and if the cause is a breakdown, then solder the damaged components yourself if you are confident in your skills, or call a repair service specialist.

Always thoroughly inspect your Miele dishwasher's components before purchasing replacement parts. It's important not only to replace the faulty component but also to eliminate the underlying cause. For example, if the water heating element relay failed due to a defective capacitor, it should also be replaced to prevent damage to the new relay.

How to get around this error?

Miele dishwashers can usually be connected directly to hot water, saving unnecessary strain on the heating element. Therefore, if your "home helper" fails to heat the water, displaying error code F24 instead, there's nothing wrong with taking advantage of this feature and avoiding the need for an expensive relay.

It's a great idea to have a water heater at home, as you can connect to it, set the desired temperature for your Miele dishwasher, wait for it to heat up, and then start the cycle. This way, the machine will be supplied with hot water at the correct temperature for the selected wash cycle. This means your "home helper" won't have to heat up the water, so no error code will appear and the cycle won't be interrupted.

Depending on the dishwasher model, the user may need to select the "Hot Water" setting. The official user manual will tell you how to activate this feature.
