Error F23 Whirlpool washing machine

Whirlpool washing machines are equipped with an automatic self-diagnosis system for problems. So, if any element fails, the washing machine will notify the user of the problem by displaying a fault code on the display. What should I do if I see error F23 on the screen? Let’s look at what could be causing this breakdown and how to deal with the problem yourself.

Possible defects

The instructions for the Whirlpool washing machine provide a description of the fault codes, their brief interpretation and possible solutions to the problems. In the vast majority of cases the error F23 signals that the tank is not filled properly with water. This was probably caused by the pressure switch. 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 “brain” of the machine are of great importance, since the process of executing any washing program depends on them.

The design of the sensor pressure switch is simple - it is a small disk and a tube immersed directly in the tank. When water is added to the washing machine, the pressure in the tube changes, which leads to the contacts on the relay closing. Thus, a signal about an empty or full tank is transmitted to the main control unit of the machine. If the pressure switch confuses the signals or sends them simultaneously, error F23 occurs.

A fault code can appear at any stage of washing: during the initial collection of water into the tank, during the rinsing step, or immediately after turning on the SMA.

The pressure switch should be inspected. Perhaps the structure is clogged or simply jammed. The reason may lie in the control unit.When intercepting a correct signal from the water level sensor, the module may incorrectly read the information and display error F23. For example, the soldering of elements on the board may be broken, the tracks may be damaged, the software may be 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 a code on the display.

Checking SM details

If you decide to start repairing it yourself, you should start inspecting the equipment. Code F23 is not the simplest. To understand how to deal with the problem, you should diagnose the internal parts of the SMA. To eliminate the error, you will have to dismantle several elements of the washing machine. If you doubt whether you can cope with the upcoming work, it is better to call an AMS repair specialist 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 to do after gaining access to 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 look for any blockages in the tube.
3. Blow lightly into the tube - you should hear characteristic clicks.
4. If you have a multimeter, test the contacts of the pressure switch with a tester.

If the pressure switch needs to be replaced, select its complete analogue in the store to avoid difficulties in the process of connecting the element.

If the water level sensor has completely passed the test and there is no need to repair it, you should inspect the heating element of the washing machine. The heater is located at the bottom of the tank body, behind the rear wall. It is not always possible to determine the breakdown of an element during a visual inspection.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 resolve is if it is caused by damage to the control module. To repair the main control unit, you must have a certain amount of knowledge and skills. To diagnose the control board you will need special tools. Perhaps the problem is a failed resistor, an algorithm failure, etc. If you have little knowledge of connecting electronic circuits, it is better not to attempt repairs yourself, but to invite a specialist.
