Ariston Washer Error Code F6

The F6 code on an Ariston washer indicates a Program Selector fault. The control board is not receiving a valid or consistent signal from the cycle selector switch. This causes the washer to stop operation to prevent running an incorrect or undefined wash program. The fault is most often related to a wiring issue between the selector and the control board.

You should not continue using the washer while F6 is active. The machine has halted because it cannot confirm which cycle has been selected, meaning it could behave unpredictably if forced to run. Addressing the fault before resuming use protects both the appliance and your laundry.

Resetting the washer by unplugging it for a few minutes may temporarily clear the F6 code, but if an underlying fault exists in the selector switch, wiring, or control board, the error will return when the machine is powered back on. A reset alone does not fix the cause of the fault. Proper diagnosis and repair of the selector circuit are required to permanently resolve F6.

A knowledgeable DIYer can attempt to diagnose F6 by first inspecting and testing the wiring harness between the program selector and the control board using a multimeter for continuity. If the wiring is intact, the selector switch itself can also be tested for correct resistance or continuity in each position. Replacing a wiring harness or selector switch is within reach for someone comfortable with basic appliance repair, but control board replacement is generally better left to a technician.

Repair costs depend on which component has failed. Wiring repairs or connector fixes can cost relatively little, often in the range of $50 to $150 for a service call if no parts are needed. A replacement program selector switch typically adds $30 to $80 in parts. A control board replacement is the most expensive outcome, with parts and labor often ranging from $150 to $350 or more.
