Fisher & Paykel Washer Error Code 26

Valve fault

Fisher & Paykel codesFisher & Paykel washer codes

Valve fault — Motor Control Module measured a voltage from the valve diagnostic circuit indicating the cold valve or both cold and hot valve or dispensing valves are faulty.

First step from the service manual

What 26 means on a Fisher & Paykel washer

Error code 26 on a Fisher & Paykel washer indicates a valve fault detected by the Motor Control Module (MCM). The MCM continuously monitors voltage signals from a dedicated valve diagnostic circuit. When the measured voltage falls outside the expected range, the MCM interprets this as a fault condition involving the cold water inlet valve, both the cold and hot water inlet valves together, or the dispensing valves. This monitoring system allows the MCM to detect electrical faults such as short circuits, open circuits, or incorrect resistance across the valve coil circuits.

The most frequent cause of this fault is a wiring harness problem rather than a failed valve itself. Connectors that have worked loose, pins that have bent backward in their housings, or wiring that has been pinched or damaged during a previous repair can all produce the incorrect voltage reading that triggers code 26. Because the diagnostic circuit is shared across multiple valves, a single wiring fault can implicate the entire valve network in the MCM's reading.

If the harness connections are confirmed to be secure and the pins are in good condition, the fault likely points to one or more failed inlet or dispensing valve solenoid coils. A failed coil will present an incorrect resistance to the diagnostic circuit, causing the MCM to flag the error. In some cases, the MCM itself may be responsible if it cannot correctly interpret or supply voltage to the diagnostic circuit, though this is a less common scenario.

Common causes of 26

  1. 01

    Loose or disconnected valve harness connectors

    Wiring / connection

    The wiring connectors at the valve bodies or at the Motor Control Module may have come loose, causing an incorrect voltage reading. Check that each connector is firmly seated and fully clicked into place.

  2. 02

    Bent or damaged connector pins

    Wiring / connection

    Pins inside the harness connectors can be pushed backward or bent, breaking the electrical contact without the connector appearing loose. Visually inspect each pin at both ends of the valve harnesses for deformation or recession.

  3. 03

    Failed inlet valve solenoid coil

    Part replacement

    The cold water inlet valve, hot water inlet valve, or both can develop an open or shorted solenoid coil, producing an abnormal resistance that the diagnostic circuit registers as a fault. A failed coil requires valve replacement.

  4. 04

    Faulty dispensing valve

    Part replacement

    The dispensing valve, which controls water flow through the detergent drawer, has a solenoid coil that the MCM monitors on the same diagnostic circuit. A failed dispensing valve coil can trigger code 26 independently or alongside an inlet valve fault.

  5. 05

    Damaged wiring harness

    Part replacement

    Chafed, pinched, or broken wiring between the valves and the Motor Control Module can create an intermittent or permanent open circuit. Inspect the full length of the valve harness for signs of wear, crushing, or insulation damage.

Frequently asked questions about 26

What does 26 mean on a Fisher & Paykel washer?
Error code 26 means the Motor Control Module has detected an abnormal voltage from the valve diagnostic circuit, indicating a fault with the cold water inlet valve, the hot and cold inlet valves together, or the dispensing valves. The MCM monitors this circuit continuously and triggers the error when the measured voltage is outside the acceptable range. This error will stop normal washer operation until the fault is resolved.
How do I fix error code 26 on a Fisher & Paykel washer?
Start by checking that all valve wiring harness connectors are fully seated at both the valve bodies and the Motor Control Module, and inspect each connector for pins that may be bent or pushed backward. If the connections are secure and undamaged, the next step is to test the solenoid coils on the cold inlet valve, hot inlet valve, and dispensing valve for correct resistance. Any valve with a failed coil will need to be replaced. If the wiring and valves check out, the Motor Control Module may need further evaluation.
Is it safe to use my Fisher & Paykel washer when error code 26 is showing?
It is not recommended to continue running the washer while error code 26 is active. A faulty valve or wiring fault can result in incorrect water fill behavior, including underfilling, overfilling, or failure to fill at all. Running a cycle with a compromised valve circuit could lead to poor wash results or, in some cases, water control issues. Resolve the fault before resuming normal use.
Will resetting my Fisher & Paykel washer clear error code 26?
A power reset may temporarily clear the error display, but the code will return if the underlying fault has not been corrected. The Motor Control Module will re-detect the abnormal voltage from the valve diagnostic circuit as soon as it performs another check. A lasting fix requires identifying and repairing the faulty wiring connection or replacing the defective valve component.
How much does it cost to repair error code 26 on a Fisher & Paykel washer?
If the fix is simply reseating a loose connector or straightening a bent pin, there is no parts cost involved. Replacing an inlet or dispensing valve typically costs between $40 and $120 for the part, depending on the specific valve and model. If a technician is needed, expect to add labor costs in the range of $80 to $180 depending on your location and the complexity of the repair.
