Asko washing machines are sleek and pleasing to the eye, thanks to their Scandinavian-inspired designs. Like any other brand, these machines will display error codes when something isn’t working correctly.

The F1 error code on an Asko washing machine refers to an overfilling problem. The most likely causes are a faulty water inlet valve or a failed water pressure switch. Unfortunately, neither of these parts can be repaired, so whichever one is affected must be replaced. That way, you can resume the regular operation of your Asko washing machine.

In this guide, we’ll dive deeper into the possible causes of the F1 error code and what you can do to fix them.

What The F1 Code Means On An Asko Washer

When your Asko washing machine displays the F1 error code, that means it’s experiencing a water supply problem caused by overfilling. The F1 error code appears when the washing machine has filled up with too much water, and in most cases, that will cause the machine to overflow out of the machine.

As you’ll see below, a washer that fills with too much water is not only bad news for the machine itself, but it also undermines its ability to wash your laundry correctly.

Possible Causes And Solutions

Let’s take a closer look at each possible cause and its solution.

Faulty Water Inlet Valve

What it is: The water inlet valve is the first item you should troubleshoot. It’s an electrically controlled component inside your Asko washer that controls the inflow of water at all times. So, for instance, when you begin a new wash cycle, the valve will open and allow water to fill the drum.

As soon as the washer senses that there is enough water inside, it will trigger the water inlet valve to close and stop the water inflow. In doing so, a valve that works correctly will prevent overfilling and the overflowing of water.

How it fails: As mentioned before, the F1 error code on your Asko washer indicates that the machine is overfilling. That’s likely because the water inlet valve has failed either mechanically or electrically.

A mechanical failure, for instance, is when there is a buildup inside the valve that prevents it from closing when it should. As a result, the washer continues to fill beyond its target volume of water.

On the other hand, an electrical failure could prevent the valve from receiving the signals to close. Remember: once the washer has enough water, it’ll signal the valve to close. This can’t happen if the valve has suffered an electrical failure.

How to fix: Whether the water inlet valve has failed mechanically or electrically, the valve cannot be repaired. Instead, you must replace it with a new water inlet valve.

You can do this by removing the washer’s top panel to gain access to the existing valve. Next, disconnect the hoses and electrical connectors, and unthread the screws that mount the valve onto the washer’s frame.

Next, mount the new water inlet valve in its place and replace the hoses and electrical connectors.

Failed Water Pressure Switch

What it is: Another component that needs troubleshooting is the water pressure switch. This component is a mechanical switch that continually senses the water levels inside your Asko washing machine.

As the drum fills with water and reaches the target volume, the switch will trigger and send signals to the washer to stop filling with water. As a result, the washer will shut the water inlet valve to stop the water inflow, and the wash cycle can begin.

How it fails: A failed water pressure switch can’t sense the water levels in the washer accurately.

In simple terms, it will never tell the washer to stop filling with water, leading to overfilling and triggering the F1 error code.

How to fix: The practical solution to this problem is to replace the water pressure switch. Again, you’ll begin by removing the washer’s top panel to access the components inside. Next, identify and locate the water pressure switch (with the help of the user manual, if necessary). 

Then, remove the hose attached to it and any screws that hold the switch in place. Of course, you’ll want to remove any electrical connectors attached to it as well.

Place the new switch in the same way as the old one, and replace all the connectors that you removed earlier.

Blocked Water Pressure Chamber or Tube

What it is: The water pressure switch described above works in three parts: the switch itself, which is then connected to a tube, which is connected to a chamber at the end.

As water fills your Asko washer, it will force air to rise through that tube gradually. Once the target water volume is reached, the air pressure will be enough to trigger the water pressure switch and stop water inflow to the machine.

How it fails: Another likelihood is that the water pressure switch is fine, though there’s a clog in the chamber or tube connected to it. So, even though the water pressure switch is working perfectly fine, it still won’t sense the water levels accurately.

All of this will lead to the Asko washer overfilling and triggering the F1 code.

How to fix: Fixing this will not necessarily require any replacement parts. Following the same steps above, remove the water pressure switch, its hose and chamber. Blow through the hose and chamber to remove any debris or detergent clogs inside, then replace those parts.

Once you’ve done that, the whole water pressure mechanism (i.e. the switch, hose, and chamber) will be able to work correctly again.

How To Clear The F1 Error Code

To clear the F1 error code, you must first identify the root cause following the troubleshooting steps detailed above. Until you’ve done that, the F1 error code will persist or come back soon after.

Once you’ve performed the necessary repairs, you can also clear the error code by resetting your Asko washer.

How To Reset An Asko Washer

Resetting your Asko washer is very straightforward. Follow these steps:

  • Firstly, disconnect the washer from its power supply. That means removing the plug from the wall socket or turning off the dedicated circuit breaker.
  • Then, press and hold the Start/Pause button for five seconds.
  • Lastly, reconnect the washer to its power supply.

Once that’s done, you can consider your Asko washer reset.

How To Test An Asko Washer After Fixing It

After fixing your Asko washer, you can test it by running a complete wash cycle from start to finish. That way, you’ll be able to see if any problems occur when the washer fills with water.

If you’re short on time, you can perform this test by selecting the shortest wash cycle available. As long as the washer fills up without displaying any error codes, that means the problem has been resolved.

How To Enter Diagnostic Mode

For a more thorough test, you can enter the machine’s diagnostic mode. This mode is often referred to as the ‘service test’ mode, and you can run it by following these steps:

  • Press P1 five times within ten seconds. That will put your machine into the service test mode.
  • At this point, each button on the control panel will correspond to a specific test. Since the F1 error code relates to the filling process, you can press the following buttons:
    • Press P1 to test the inlet valve leading to the prewash compartment
    • Press P2 to test the inlet valve leading to the main wash compartment
    • Press the Menu button to test the inlet valve leading to the softener compartment
