Fisher & Paykel Washer Error Code 106

Error code 106 means the Display Module has detected a failure in the communications link between itself and the Motor Controller Module. The washer stops operation because the two boards can no longer exchange the data needed to run a cycle safely. The root cause can be a shorted drain pump, faulty wiring, or a failed control board.

No, you should not attempt to run the washer while error code 106 is active. The machine has shut down because the control system cannot operate reliably without proper communication between the two control boards. Continuing to run it could cause further damage to the electronics or leave laundry in standing water.

Repair costs depend on which component has failed. Drain pump replacement typically runs in the range of $100 to $250 including parts and labor. Wiring harness repairs can vary widely depending on the extent of the damage. If a control board needs to be replaced, costs can range from $150 to $400 or more, depending on the specific module and local labor rates.

Start by measuring the resistance of the drain pump with a multimeter. If the reading is below 33 ohms, the pump has an internal short and needs to be replaced. If the pump tests within range, inspect the wiring harness and connectors between the Display Module and Motor Controller Module for damage or loose connections. If no wiring faults are found, one of the two control boards will need to be tested and likely replaced.

A reset may temporarily clear the code and allow the washer to attempt another cycle, but the error will return if the underlying fault is not repaired. If a shorted pump or damaged wiring is present, the communications failure will reoccur as soon as the machine tries to operate. A proper diagnosis and repair is necessary for the code to clear permanently.
