Indesit Dryer Error Code F15

F15 means the dryer's control system has detected that the upper heating element is active when it should be switched off. This is a safety fault that causes the dryer to stop operating to prevent overheating. The issue typically involves the control module connector J4, a failed relay on the control board, or a wiring fault in the element circuit.

No. The F15 fault indicates the upper heating element may not be shutting off correctly, which creates a risk of overheating. You should stop using the dryer until the fault is diagnosed and repaired. The dryer may also refuse to run in this condition as a built-in safety measure.

Repair costs vary depending on the root cause. If the fix is simply reseating the J4 connector, the cost may only involve a service call fee, typically in the range of $60 to $120. If a new control board is required, parts and labor combined can range from $150 to $350 or more depending on your location and the specific board needed.

The first step, checking and reseating the J4 connector on the control module, is something a confident DIYer can attempt after unplugging the dryer. However, diagnosing a failed relay, triac, or shorted wiring requires a multimeter and knowledge of appliance electrical circuits. If the connector check does not resolve the fault, professional repair is recommended due to the high-voltage components involved.

A power reset may temporarily clear the fault code, but if the underlying problem remains, the F15 error will return once the dryer runs and the control board detects the upper element is on when it should not be. Resetting without repairing the root cause is not a reliable fix and leaves the overheating risk in place.
