AEG Washing Machine Error Code E21/E22/E23/E24

Washing machines allow us to effortlessly clean our clothes without you having to do any of the hard work. Hence the reason why when the washer breaks down, it almost feels like the end of the world.

If your washing machine is beaming at you with either an E21/E22/E23 or E24 error code, then most likely there is a problem with draining the water. Now that can be an issue if you’re waiting on the kid's school uniform to wash. To help identify the causes we have investigated the more common faults which may arise.

Hopefully, by reading this article we may be able to get your washer to lose the water weight so that it’s ready for the next cycle.

Cause 1

Blocked Filter

Most washing machines won’t start a spin cycle until they’ve fully drained the water from the wash.

If your machine is draining very slowly or not at all the most likely cause is a blockage somewhere in the drainage system and the most common is the filter.

Safety First! Please make sure that you have disconnected the appliance from the mains before beginning any repair.

The best way to check if your filter is blocked is to:

  • Drain the water from the machine by lowering the drain hose below the water level to a bowl or your machine may have a drain hose near the filter
  • Place a towel under the filter and pull the filter out to remove any debris that may have gathered. 
  • Check the pump impeller inside the housing turns freely and is not obstructed.

eSpares Top Tip: Check your filter as part of your regular maintenance to ensure your washer runs smoothly and ensure no drainage problems.

If the filter is damaged a replacement will need to be fitted, and you can see our extensive range of washing machine filters here within our extensive selection of washing machine spares.

Cause 2


The washing machine needs to drain the water for it to finish the program, if this is not happening then you could be faced with a faulty drain pump.

On some AEG machines, a common reason to your pump failing can be due to a blockage, if blocked by loose change or hair grips the pump will fail leading to the appliance to continue to run.

Safety First! Please make sure that you have switched your appliance off at the mains before starting your repair.

  • If upon inspecting the pump you notice debris you will need to remove this.
  • The impeller will jam - this should rotate easily - it’s magnetic which should cause the impeller spring back to a number of stop positions If unblocking the pump makes no change then you will need to test the pump using a multimeter.
  • Using a multimeter you need to check for resistance, you should be looking at a reading of 100 - 300 Ohms. (See here for instruction on how to use a multimeter)

Anything higher or no resistance then the pump has failed and will require a replacement.

If a replacement is needed then head over to our washing machine page where we have an extensive range of spare pumps to help restore your washer.
