What Does Error Code E23 Mean on an Electrolux Washing Machine?
Clean the drain pump filter to remove any blockage that may be overloading the pump's electronics — remove the filter cover at the front bottom of the machine, clear out any debris, refit the filter, and restart the cycle (takes about 10 minutes).
Fault description
Error code E23 on an Electrolux washing machine points to an electronic fault within the drain pump. Unlike a simple blockage error, E23 specifically means the machine's control board has detected a problem with the pump's electronic components — this could be a failed motor winding, a short circuit inside the pump, or a wiring issue between the pump and the main board.
When E23 appears, the washing machine will typically stop mid-cycle, often leaving water sitting in the drum. The machine cannot complete the drain phase and will lock the door until the fault is resolved. In some cases the display will flash the code repeatedly, and the machine will not respond to further programme selections until the issue is cleared.
While the fault description points to electronics, it is worth ruling out mechanical causes first — a severely blocked filter or kinked drain hose can place enough strain on the pump to trigger an electronic fault code before any component actually burns out.
Causes
- Blocked or clogged drain pump filter — A heavily blocked filter forces the pump motor to work harder than it is designed to, causing it to overheat or draw excess current. This electrical stress can trigger the E23 fault code even if the pump itself is not yet permanently damaged.
- Failed drain pump motor or internal winding — Over time, the pump's internal motor windings can burn out or short circuit, causing the control board to detect an abnormal electrical signal. This is one of the most common reasons E23 appears on older machines or those that have run many cycles.
- Damaged or loose wiring between the pump and control board — The wiring harness connecting the drain pump to the main control board can become loose, corroded, or chafed over time. A poor connection will cause intermittent or incorrect signals that the board interprets as an electronic pump fault.
- Foreign object jammed in the pump impeller — Small items such as coins, hair clips, or buttons can pass through the filter and lodge in the pump impeller, preventing it from spinning freely. A seized impeller causes the pump motor to stall, which can register as an electronic fault.
- Faulty main control board — If the control board itself has developed a fault, it may misread signals from a perfectly functional pump and incorrectly display E23. This is less common but should be considered if the pump and wiring have both been checked and found to be in good condition.
Step-by-Step Fix
- 1
Power cycle the machine
Switch the washing machine off at the mains and unplug it from the wall socket. Wait at least 5 minutes before plugging it back in and selecting a drain or spin programme. A temporary electronic glitch can sometimes cause E23 to appear, and a full power reset will clear it.

Clean the drain pump filter
Locate the filter access panel at the bottom front of the machine — it usually pulls open or unscrews. Place a shallow tray and some towels underneath before opening the filter cap, as water will spill out. Remove the filter completely, rinse it under a tap, clear any debris from the filter housing, then refit it securely and run a drain cycle.
- 3
Check the drain hose for kinks or blockages
Pull the machine slightly away from the wall and inspect the drain hose along its full length. A kinked or squashed hose restricts water flow and puts extra load on the pump. Straighten any kinks and ensure the hose end is not pushed too far into the standpipe, which can cause a siphoning effect.
- 4
Inspect the pump impeller for obstructions
With the machine unplugged, remove the filter again and use a torch to look into the pump housing. You should be able to see the impeller blades — try turning them gently with a finger or a small flat-head screwdriver. If the impeller is stiff or will not turn at all, there is likely a foreign object lodged inside that needs to be removed.
- 5
Check the pump wiring connections
If you are comfortable doing so, carefully pull the machine out and remove the back or bottom panel to access the pump. Check that the wiring connector at the pump is firmly seated and that there are no visible signs of burning, corrosion, or broken wires. Reseat any loose connectors and inspect the harness for damage along its length.

Test or replace the drain pump
If all the above steps have been completed and E23 persists, the pump itself is likely faulty. Drain pumps for Electrolux washing machines are a commonly available spare part. The pump is typically held in place by a clamp and two or three screws, making it a manageable replacement for a confident DIYer — ensure the machine is unplugged and fully drained before attempting this.

When to call a service technician
If you have cleaned the filter, checked the hose, cleared the impeller, and reseated all wiring connections but the E23 code returns as soon as you run a cycle, the pump motor has most likely failed internally and needs to be replaced. If you are not comfortable accessing internal components or removing panels, a service technician can do this safely and confirm whether the pump or the control board is at fault.
You should also contact a service technician if you notice any burning smell coming from the machine, if the pump makes a loud grinding or humming noise without draining, or if there are visible scorch marks near the pump or wiring. These signs suggest a more serious electrical fault that should not be ignored.

Frequently Asked Questions
Can I still use my Electrolux washing machine with error code E23 showing?
No — when E23 is active, the machine will not complete a cycle and the door may remain locked. Attempting to force a cycle could cause further damage to the pump or control board. Resolve the fault before using the machine again.
Will clearing the filter always fix E23?
Cleaning the filter fixes E23 in a significant number of cases, particularly if the code has appeared for the first time. However, if the pump motor has already burned out due to prolonged strain, cleaning the filter alone will not be enough and the pump will need to be replaced.
How do I drain the water from the drum before I can access the filter?
Most Electrolux machines have a small emergency drain hose tucked behind the filter access panel. Pull this hose out, remove its cap, and let the water drain into a bowl or tray. This allows you to safely open the filter without flooding the floor.
How much does it cost to replace a drain pump on an Electrolux washing machine?
A replacement drain pump for an Electrolux washing machine typically costs between £20 and £50 for the part, depending on the model. If you hire a service technician to fit it, expect to add a call-out and labour charge on top of the part cost.
Could E23 be caused by a power surge rather than a physical fault?
Yes, in some cases a power surge or brief interruption to the electricity supply can cause the control board to log a false E23 code. A full power cycle — unplugging the machine for at least five minutes — will often clear a surge-related fault. If the code does not return after a reset and a full wash cycle, no further action is needed.
