Fisher & Paykel Washer Error Code Err 10

Err 10 indicates that the heater NTC thermistor has malfunctioned. The NTC is a temperature sensor that monitors water temperature during the heating portion of the wash cycle. The error appears at the end of the program, meaning the washer completes its cycle before displaying the fault code. It points to either a wiring issue or a failed sensor component.

Because the error appears at the end of the cycle, the washer may continue to run, but the water temperature during the wash may not be correctly regulated. Running the machine repeatedly with a faulty temperature sensor risks clothes being washed at incorrect temperatures and could potentially stress other heating components. It is best to diagnose and resolve the fault before continuing regular use.

If the issue is simply a loose connector, there may be no parts cost at all. Replacing the NTC thermistor is generally an affordable repair, with parts typically ranging from around $15 to $60 depending on the model and supplier. If the display PCB requires replacement, costs can rise considerably, often ranging from $100 to $300 or more for parts alone, plus any labor charges if a technician is involved.

The first step, checking the wiring harness connections at the NTC sensor and at the CN14 connector on the display PCB, is something a confident DIYer can do safely with the machine unplugged. If the connectors are secure and the error persists, testing and replacing the NTC thermistor is also within reach for someone comfortable with basic multimeter use. However, if the fault traces back to the display PCB, professional diagnosis is recommended.

A reset may temporarily clear the error display, but if the underlying fault with the NTC thermistor or its wiring is still present, the code will return at the end of the next cycle. A reset alone is not a fix. The wiring connections and thermistor should be inspected and tested to address the root cause.
