Washing Machine
E52
The E52 error code on an Electrolux washing machine signals a fault with the motor’s tachometer signal — specifically, the control board is not receiving a valid speed reading from the motor. It’s a moderately serious fault that will stop your machine mid-cycle, but it’s not always an expensive fix.
What does this error mean?
The E52 code means the washing machine’s main control board is detecting an abnormal or absent signal from the motor tachometer (also called a tacho generator), which is a small sensor that tells the board how fast the drum is spinning. Without this feedback, the machine cannot safely control wash or spin speeds, so it shuts down to protect itself. This is different from the motor failing entirely — the motor itself may be fine, but the signal it’s sending is corrupted or missing.

🔍 Likely causes
🛠️ Step-by-step fix
Reset the machine: Turn the washing machine off at the plug, wait 10 minutes, then switch it back on. Restart the cycle. A temporary signal glitch can occasionally trigger E52, and a hard reset clears it.
Check the load: Remove laundry, redistribute it evenly, and try a short spin-only cycle. An extreme imbalance can sometimes stress the motor enough to trigger a speed signal fault.
Inspect the wiring harness (visible connections only): Pull the machine away from the wall, unplug it, and carefully check the wiring connector at the rear of the motor for any loose, burnt, or corroded pins. Firmly reseat any loose connectors. Do not open sealed electrical components.
Check the carbon brushes: On many Electrolux motors, the carbon brushes are accessible from the outside of the motor body without fully disassembling the machine. If they are worn down to less than 5mm, replace them — brushes are inexpensive (£8–£20 for a pair) and a common DIY fix. Look up your specific model number to confirm brush access.
Replace the tachometer sensor: If the brushes look fine, the tacho sensor itself is the next most likely culprit. Source the correct part using your full model number (found inside the door frame). Sensors typically cost £15–£35. Replacement involves accessing the motor — only attempt this if you are comfortable with basic appliance disassembly and the machine is fully unplugged.
If none of the above resolves E52, stop and call a professional — the fault likely lies with the motor windings or main PCB, both of which require specialist diagnosis.
📞 When to call a professional
Call an appliance engineer if the error persists after checking the brushes and wiring, or if you are not comfortable accessing the motor. Tell the engineer: ‘My Electrolux washing machine is showing error code E52 — I believe it’s a tachometer or motor fault.’ This helps them arrive prepared with the right parts and avoids a wasted call-out.
⚖️ Repair or replace?
A professional repair for E52 — covering diagnosis, carbon brushes, or a tachometer sensor — typically costs £80–£140 in the UK. If the motor itself needs replacing, expect £150–£250 all-in. For machines under 7 years old, repair is almost always worth it; for machines over 10 years old, weigh the repair cost against a new mid-range Electrolux or equivalent at £350–£550 — replacement becomes the smarter choice if the motor has failed.
