Dryer shows F18 and may not start or may shut down unexpectedly.

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

Unstable mains frequency, inverter or power supply mis-detection, internal control board fault

Safety first: Unplug the dryer before inspecting internal components.

Basic checks:

Confirm that the dryer is connected directly to a suitable wall outlet, not through an undersized extension cord or generator with unstable frequency.
If using backup power or an inverter supply, switch to normal mains power and test again.
Inspect the line filter and control board for visible damage.
If F18 continues on a stable mains supply, the internal power measurement circuit may be defective; contact a qualified technician.
