What does the AEG E23 error code mean?

The AEG E23 error code indicates an electrical fault within the drain pump circuit. This means the washing machine is detecting a problem with the way power is being delivered to, or used by, the drain pump.

This fault can be caused by:

1. A failed or shorted drain pump
2. Damaged, loose, or corroded wiring
3. A fault in the main control board (PCB)
4. Moisture ingress affecting electrical components

Unlike simple drainage issues (like blockages), E23 is specifically related to electrical integrity, which is why it is considered more serious.

Symptoms

You may notice one or more of the following before or alongside the error code:

1. The machine fails to drain water
2. The cycle stops mid-program
3. The drain pump does not run at all, or runs intermittently
4. A buzzing or clicking sound without proper draining
5. The machine may trip electrics in severe cases
6. Burning smell or visible signs of damage (rare, but serious)

How to fix the Miele AEG E23 error code

Reset machine

Unplug the appliance from the mains and leave it for 10–15 minutes.
This can sometimes clear temporary faults or control board glitches.

Check wiring connections

If you are confident and it is safe to do so:

1. Inspect accessible wiring to the drain pump
2. Look for loose connectors, frayed wires, or corrosion
3. Ensure all connections are firmly seated

⚠ Always unplug the machine before inspecting.

Inspect pump for damage

1. Check the pump for blockages or foreign objects
2. Listen for operation — a completely silent pump may indicate failure
3. Look for signs of burning, overheating, or leakage

If the pump is electrically faulty, it will usually need replacing.
