Repair or replace?
Dryers typically last about 12–14 years. Service documentation for this platform dates from about 2015, so the oldest units built on it are now around 11 years old. The age printed in the serial number, the repair cost and the condition of the rest of the appliance decide it. Use the repair-or-replace guide.
Models built on the same platform
These models share this platform's service documentation, so fault codes and most diagnostic steps are the same.
