The display of error code E1 F9 on the whirlpool duet washing machine could also be warning you about the machine’s issue with spinning and draining functions.

What Does an “E1 F9” Error Message Mean?

The “E” in the error message E1 F9 means that there’s a problem with your washing machine’s electronic control board, also known as the computer. The “F” stands for fault and 9 is an internal code within the computer.

This means that it is referencing a specific area of the washing machine. The fault code is referring to a specific sensor.

The sensor code F9 means that there’s a malfunction with your water level switch. This part is located on the side of your washing machine, near where the hoses connect to it.

The sensors are critical because they tell your machine how much water you’ve put into the drum versus detergent and how much water is left for the spin cycle. These sensors also tell your machine when to switch between cycles and spin or drain functions.

Causes of Error Code E1 F9

The most probable cause of this error code is the malfunctioning Drain System, the components of this system are the following:

  • Filter
  • Pump
  • Drain hosepipe
  • Power outage
  • Loose Plug

Fixing the Error Code E1 F19

You can eliminate the possibility of this error being caused by something simple by unplugging your washing machine and giving it up to an hour for the internal circuits to reset.

However, if you see this message again after that time period, then you need to check the sensor that is causing the problem. For that, follow the steps below:

  • Turn off the machine from the mains.
  • Locate the hosepipe and clean it thoroughly.
  • Similarly, check the filter as well and clean it properly.
  • Now, proceed to the pump by removing the top panel.
  • Examine its connections, replace them in case of any issues.
  • Also, use a multimeter to test the wires. The resistance should be around 16 Ohms. If it isn’t, there is something wrong with the wires.
  • Also, check the pump with a multimeter and examine its connections.
  • If the pump seems to be in order, then you have to inspect the control board. If the control board is faulty, then you have to seek a professional’s help in this case.


To conclude, an “E1 F9” error message on your Whirlpool Duet Washing Machine is due to a malfunctioning level sensor. However, before you do any troubleshooting, make sure that there are no loose connections anywhere in the plumbing to your washing machine.

If all hoses are secure and tight and the water inlet valve is understandable and the electronic control board on your washing machine is secured, then you’ll want to order a new control board for your washing machine and replace it.
