Whirlpool washer F20 error Code. How to fix it?

whirlpool error code

Modern Whirlpool washers have the function of displaying an error code if something goes wrong. Many errors begin with the letter F. Sometimes, owners of washers may see an F20 error code on display.

The F20 code means that the washing machine does not receive water. This trouble can happen for several reasons, which can be related to both the breakdown of internal parts and the water shutoffs at the city level. We advise you to call an appliance repairman. It will be a better idea because a repairman has experience solving such troubles and can take the necessary tools for the repair. But if you’d like to try it yourself, we’ll give you some tips on how you can try to cope with it. 

Do not forget that during the diagnosis and repair of your Whirlpool washer, you should follow the safety rules, including:

  • Disconnecting it from the power supply;
  • Shutting off the taps that supply water to the washing machine.

Reasons for F20 error code in the Whirlpool washer

Suppose your washing machine is showing F20 error code. In that case, it may be due to several reasons such as: the closed water tap, problems with access to water, water supply hose problems, clogged filter screens, malfunction of the control board, or problem with the pressure switch.

Let’s look in detail at these reasons:

  • The water tap (inlet faucet) is closed

It may not seem like an obvious reason; however, if both taps are not working correctly, this can cause an F20 error code. It happens because water does not enter the washing machine.

  • Problems with access to water

The problem may be that your home or area does not have a regular water supply. Also, low water pressure can cause this error.

  • Water supply hose problems

The water hoses can clog or have a kink in them. If there are any obstacles in the way of the water passing through the hose, it will cause the F20 code error

  • Clogged filter screens

Both taps are connected to the washer using water inlets. These valves have screens that filter debris. If they are stuck, it can also be the reason for the lack of access to water.

  • Malfunction of the control board

If you haven’t found a problem in the previous steps, you need to check your control board malfunction. A failure of the control board can also cause an error code to occur on your washing machine.

  • Problem with pressure switch

The pressure switch is necessary to control the amount of water inside the drum. In case of a large amount of water in the drum, the pressure switch informs the control panel about this problem preventing water from entering the tub. In addition to the water supply, the relay performs several more important functions for the full operation of the washing machine.

If the hose is clogged or damaged in any way, the relay does not work correctly or fails altogether.

How to fix the Whirlpool washer F20 error

Let’s analyze the methods for solving the problem associated with the F20 error code. It is necessary to make sure both taps are working properly, find out if there is water in your district, check the hose that supplies water to your washing machine, check water intake screens and clean if necessary, repair the control board, and check the pressure switch.

  • The water faucet is closed 

Make sure both taps are working correctly. Although some people do not take this point seriously, you should check the hot and cold water supply. It can also be the cause of your problem.

  • Problems with access to water 

Find out if there is water in your district. As we have said, the problem with the F20 error code may also be because your house or district has a problem with access to water. In this case, you need to ask your neighbours if everything is in order with their water supply.

If you have any questions, you need to call the local water utility.

  • Water supply hose problems 

Check the hose that supplies water to your washing machine. It must not be clogged. If the hose is damaged, you need to replace it with a new one. 

Check water intake screens and clean if necessary. Follow these instructions to check for clogged water intake screens:

  1. Unplug your washing machine first;
  2. Turn off hot and cold water taps;
  3. After that, remove all debris from the water intake screens.

Assemble all components, connect your washing machine and test it out.

  • Malfunction of the control board. 

Repair control board. If your washing machine has a malfunction in the control board, you need to follow these steps:

  1. To get started, you need to try double-clicking a button like Pause/Cancel (it might also be called Enable/Disable).
  2. If the previous point hasn’t helped you, you should unplug the washing machine from the power for a few minutes. It will help your washer dissipate the electrical current and restart the washing machine.
  • Problem with pressure switch

Check the pressure switch. The next thing you need to check the pressure switch for suitability. To do this, follow the next items:

  1. Disconnect the Whirlpool washer from the power supply;
  2. Remove the washers to gain access to the pressure switch;
  3. Disconnect the camera and remove the screws holding it together and the wiring harness;
  4. Check the hose for debris and damage;

Check the pressure switch using a multimeter by connecting the sensors to the terminals on the outside. Fill the washer with water by blowing it into the relay hose. At this point should check the resistance. If the reading does not change, the pressure switch needs to be replaced.
