Zanussi Intermittent Power Loss / Thermal Trip

Unit shuts off randomly during use without showing an error code

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

Loose internal power connector, Failing thermal cut-out, Overheating motor, Faulty on/off switch contacts

Safety: Unplug before opening the housing.

Check ventilation: Ensure all Zanussi vents and filters are clean to prevent overheating.
Inspect wiring: Open the body and check all push-on connectors on the switch, motor, and PCB. Tighten or crimp loose terminals.
Test switch: Use a multimeter to check the on/off switch for intermittent contact when toggled. Replace if unstable.
Check thermal cut-out: Locate the thermal protector on the motor. If it opens at low temperature or has poor connections, replace it.
