How to eliminate E21 error in electrolux washing machine?
- Error: E21
- Description: Water washing water was not poured into the established time (10 minutes).
- Solution: Obstructed drainage system (nozzles, filter, pump). The drain pump is out of service. Make sure the drain pump winding resistance is approximately 170 ohms. Damage may occur due to the electronic module failure.
If you encounter the E21 error code when starting your Electrolux washing machine, it is possible that water is not draining fast enough. This could be due to an obstruction in the drainage pipe, a faulty drainage pump, a pressure sensor, or a malfunctioning motherboard. Additionally, your washing machine may not be spinning and making unusual noises.
Fortunately, this problem can be easily solved by following some simple steps that we explain below.
Check the Drainage Hose
The first thing you should do is check the drainage hose. It may have moved from its correct position, so make sure it is properly installed. The hose should not be more than 10 cm into the drain and should be at a height between 60 and 100 cm from the base of the washing machine. Also, check that there are no twists or bends in the hose. If there are, straighten it and see if the problem is solved.
Check for Obstructions in the Drainage
If you hear noise, there might be an obstruction in the drainage, so you should check it. Look at the hose connected to the sink siphon and make sure water is draining normally. Then, check where the drainage hose is connected to wastewater, which is likely where the obstruction is.
If necessary, you can hold the hose and remove it to check for any obstructions inside. But before doing so, make sure you have a bucket and towels handy to catch any spills.
Rest the Washing Machine
It is recommended that you turn off the washing machine and let it rest for a couple of hours before attempting the washing cycle again. Sometimes, a bimetallic fuse cuts off power to the pump if it is blocked, but it works normally after the pump cools down.
If this does not solve the problem, move on to check for obstructions in the pump and filter.
Check the Pump and Filter
The next thing you should do is check for obstructions in the pump and filter. This also includes cleaning the blades of the pump. You can turn the visible blades with a pencil.
Once you have cleaned the pump and filter with clean water, check if the washing machine works. If it does, run a short cycle of just water to clean the entire drainage system. Then, run a diagnostic cycle to detect any other error codes or warnings.

What to Do If Nothing Works?
If none of the above steps solve the problem, check the drainage pump and motherboard. This may take some time, but by following the steps correctly, you can solve the problem.
First, check that the input power to the drainage pump is 120 VAC. If it is lower, check the cable connections.
If everything is correct, check the resistance measurement of the drainage pump. To do this, use a multimeter at the motherboard connector between J4-3 and J4-4. The resistance should be between 13 Q and 16 Q. You can buy a device to measure resistance at a local hardware store.
If the resistance measurement is incorrect, check the drainage pump directly. If the pump is faulty, you will need to replace it. If the measurement is correct, check and replace the pump wiring.
If the resistance measurement on the motherboard is correct, check the pump rotor. It may be blocked or broken. Clean the rotor and check if the washing machine works. If it doesn’t, you’ll need to replace the pump.
If you need to access the drainage pump, follow these steps:
- Disconnect the washing machine.
- Remove the screws that hold the panel.
- Tilt and lift the panel up to remove it.
- Locate the drainage pump, which is connected to the hose, at the bottom of the panel.
- Disconnect the pump clamp and remove the drainage hose.
- Remove the motor belt from the pump pulley.
- Turn the pump pulley. If it doesn’t turn easily, it’s probably blocked by something. Put your finger in the drainage outlet and touch the blades to see if they are broken or blocked.
- Use a flashlight to see if there are any broken parts inside.
- Remove any obstruction. If the pump is broken, you’ll need to call an appliance repair technician to replace it.
With these simple steps, you can solve the E21 error code issue in your Electrolux washing machine and save on repair costs. Remember to always follow safety instructions when handling the washing machine and disconnect it before making any repairs. If you have any doubts or issues, you can always contact an appliance repair technician to help you.
