Dryer function locked out; F15 displayed, sometimes after overheating.

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

Stuck dryer heater relay on PCB, Overheat event triggering safety lockout, Faulty main control board, Shorted dryer heater

Safety: Unplug the appliance. Do not attempt to run the dryer if overheating is suspected.

Allow full cool-down: Leave the machine unplugged for at least 30 minutes to allow thermostats to reset.
Clean airflow path: Remove lint from the dryer duct, fan, and condenser (if fitted). Blocked airflow can cause repeated overheating.
Check heater and thermostats: As with F14, test the heater and safety thermostats. Replace any failed components.
Inspect PCB: Look for a welded or burnt dryer relay on the main control board. If damaged, replace the PCB.
