Washer-dryer combo shows E40; typically related to motor or tachometer issues in some Asko models.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed tachometer sensor on motor, Loose tachometer wiring, Defective motor, Faulty motor control circuit

Safety: Unplug the unit before accessing the motor.

Inspect wiring: Remove the rear panel and locate the motor tachometer connector. Ensure it is firmly seated and wires are intact.
Test tachometer: Use a multimeter to measure resistance across the tachometer terminals. Compare with Asko specifications; an open circuit indicates failure.
Check motor: If tachometer is good, test motor windings for continuity and shorts to ground.

Persistent E40 usually requires motor or control board replacement by a technician.
