Error E52 in Electrolux washing machine

Error E52 in Electrolux washing machine

Error: E52

Description: No signal from the motor tachometric generator (tachometer). This means the electronic control board is not receiving the proper speed/position feedback from the motor.

What does Error E52 mean?

Error E52 indicates a communication problem between the motor’s tachometric generator and the machine’s control electronics. The tachometer works like a speedometer for the motor: if its signal is missing or incorrect, the control board cannot regulate motor speed, so the machine reports E52.

Possible causes

• Faulty tachometric generator (tachometer) inside the motor
• Damaged motor components (brushes, coils) or mechanical seizure
• Wiring/connectors between motor and electronic board are open, shorted or corroded
• Defective components on the electronic control board (triac, relay, drivers) or a damaged board

Step-by-step diagnosis and solution

1. Safety first

   Unplug the appliance before any inspection or repair. If you are not experienced with electrical appliances, contact a professional.

2. Visual and mechanical checks

   Manually spin the drum. If it does not turn freely, the motor or drum bearings may be seized or obstructed. Inspect for obvious damage, burnt smells or loose connectors.

3. Check motor components

   Inspect motor brushes, coils and the tachometer assembly for wear or damage. Worn brushes or open coils can cause loss of tachometer signal. Replace faulty motor parts as needed.

4. Inspect wiring and connectors

   Examine the harness between motor and control board for broken wires, corrosion or poor contacts. Use a multimeter to verify continuity and resistance at the connector pins on the board. Replace or repair damaged wiring or connectors.

5. Test electronic board components (triac, relays, drivers)

   If motor and wiring tests are good but the error persists, the problem may be on the electronic board. Components that commonly fail include triacs and relays that drive the motor. A faulty triac may prevent proper motor control or tachometer reading.

   Replacing or repairing the control board or its power-stage components is often required; this should be done by a qualified technician.

6. When to replace parts

   If measurements show open/shorted motor windings, damaged tachometer, or irreparable board faults, replace the defective component (motor or control board). Always follow manufacturer part numbers and installation instructions.

Notes specific to Electrolux dryers

Although this article focuses on washing machines, Electrolux dryers can show the same E52 symptom with a similar root cause: motor or motor driver (triac) failure and loss of tachometer signal. Diagnosis and repair steps are essentially the same: check motor internals (brushes, tachometer, coils), wiring, and the electronic control components (triac, relay).

Tools and skills required

• Basic hand tools and safety equipment
• Multimeter to check continuity and resistance
• Ability to safely access motor and control board
• Experience to identify faulty electronic components (recommended a technician for board-level repairs)

Maintenance and prevention

• Keep filters and hoses clean to reduce strain on the motor
• Do not overload the appliance
• Ensure proper installation and stable leveling to avoid excessive vibration
• Periodic inspection of motor brushes and wiring can prevent failures

When to call a professional

If you are not comfortable with electrical diagnostics, if tests require replacing the electronic control board or triac, or if the motor shows internal faults, contact an authorized service technician. Incorrect handling can cause further damage or safety hazards.
