Indesit Dryer Error Code F08

F08 means the dryer's control system has detected that the lower heating element is energised when it has been commanded to be off. This is a safety-related fault that causes the dryer to stop operating. It can be caused by a faulty connector, a stuck relay or triac on the control board, a wiring short, or a defective element. Diagnosis should begin with checking connector J4 on the control module.

No, you should not continue using the dryer while F08 is active. The error indicates the lower heating element may not be shutting off correctly, which creates a risk of overheating. Disconnect the dryer from the power supply until the fault has been diagnosed and repaired.

Repair costs depend on the cause. If only the connector needs reseating, there may be no parts cost, just a service call fee typically in the range of $60 to $120. If the control board needs replacement, parts and labor combined can range from $150 to $300 or more depending on your region and the specific board required. A wiring harness repair falls somewhere in between.

The first step, checking and reseating connector J4, is straightforward and can be done by a confident DIYer after unplugging the machine from the mains. However, if the fault lies with the control board relay, triac, or wiring harness, the repair becomes more involved and carries electrical safety risks. Board replacement and harness repairs are best handled by a qualified technician.

A power reset may temporarily clear the displayed error, but it will not resolve the underlying fault. If the root cause, such as a welded relay, shorted triac, or wiring issue, is still present, the F08 code will return as soon as the dryer attempts to operate. The fault must be physically repaired before the error will clear permanently.
