Whirlpool washing machine error F23

Whirlpool washing machines are equipped with an automatic self-diagnosis system. If any component fails, the washing machine will notify the user of the problem by displaying an error code on the screen. What should you do if you see error code F23 on the screen? Let's look at the possible causes of this malfunction and how to troubleshoot it yourself.

Possible defects

The Whirlpool washing machine manual provides a description of error codes, their brief interpretation, and possible solutions. In the vast majority of cases, the error F23 signals that the tank is not filled with water correctly. The pressure switch is likely the culprit. The sensor transmits a signal about the water level in the tank to the control module. The readings sent by the pressure switch to the machine's "brain" are crucial, as they determine the execution of any washing program.

The pressure switch's design is simple: it consists of a small disk and a tube immersed directly in the washing machine's drum. As water fills the washing machine, the pressure in the tube changes, causing the relay contacts to close. This sends a signal to the machine's main control unit indicating whether the drum is full or empty. If the pressure switch confuses the signals or sends them simultaneously, error code F23 occurs.

The error code may appear at any stage of the wash cycle: when initially filling the tank with water, during the rinse step, or immediately after turning on the washing machine.

The pressure switch should be inspected. It's possible that the element is clogged or simply jammed. The problem could lie in the control unit. While intercepting a valid signal from the water level sensor, the module may misread the information and display error F23. For example, the soldering of components on the board could be faulty, the tracks damaged, the software reset, etc. Less commonly, error F23 is caused by a faulty heating element. Even a small defect in the heating element can cause a short circuit and display the error code.

Checking the SM details

If you decide to do the repairs yourself, you should begin by inspecting the equipment. The F23 code is not the easiest to detect. To understand how to resolve the problem, you should diagnose the internal components of the washing machine. To fix the error, you will have to dismantle several parts of the washing machine. If you are unsure whether you can handle the upcoming work, it's best to call a washing machine repair technician for help.

The first step is to check the pressure switch. The water level sensor is located under the top cover of the Whirlpool washing machine, on one of the walls. What should you do after accessing the pressure switch?

1. Carefully inspect the element, check that there are no defects on its body.
2. Disconnect the pressure switch from the washing machine body and check if there are any blockages in the tube.
3. Blow lightly into the tube – you should hear characteristic clicks.
4. If you have a multimeter, use a tester to test the pressure switch contacts.

If the pressure switch needs to be replaced, select a complete equivalent in the store to avoid complications during the connection process.

If the water level sensor has passed the test and does not need to be repaired, you should inspect the washing machine's heating element. The heater is located at the bottom of the tank body, behind the rear wall. A visual inspection doesn't always reveal a faulty element. The heating element is tested with a multimeter, and the resistance of the heater is measured. The faulty element should be replaced with a new one.

The most difficult error to fix is ​​one caused by damage to the control module. Repairing the main control unit requires a certain amount of knowledge and skill. Diagnostics of the control board will require specialized equipment. The problem could be a faulty resistor, an algorithm glitch, or something else. If you're not very familiar with connecting electronic circuits, it's best to call a professional instead of attempting the repair yourself.
