What 35 means on a Fisher & Paykel washer

Error code 35 on a Fisher & Paykel washer indicates a Phase 1 Motor Control Module Reset Error. This fault is triggered when the Display Module sends a false or erroneous reset signal to the Motor Control Module (MCM). The two modules communicate continuously during operation, and when the MCM receives an unexpected reset command from the Display Module, it logs this fault and halts normal operation to prevent potential motor damage or unsafe cycling behavior.

The communication between the Display Module and the Motor Control Module travels through a 12-way wiring harness. This harness carries both control signals and feedback data between the two boards. If any of the 12 pins in this connector are corroded, bent, loose, or intermittently contacting, the signal integrity can be compromised, causing the Display Module to inadvertently send a reset command that the MCM interprets as a fault condition. This is the most common root cause and should always be checked first.

If the harness and connector are found to be in good condition, the fault may point to a failing Display Module that is generating incorrect output signals, or less commonly, a Motor Control Module that is misinterpreting valid signals due to internal component degradation. In either case, accurate diagnosis requires systematically eliminating the wiring harness as a cause before condemning either control board, as board replacements represent a significantly higher cost and complexity than connector inspection and repair.

Common causes of 35

  1. 01

    Loose or faulty 12-way harness connection

    Wiring / connection

    The 12-way wiring harness connecting the Display Module and Motor Control Module is the first component to inspect. A loose, corroded, or partially seated connector can cause signal errors that trigger this fault.

  2. 02

    Corroded or damaged harness pins

    Part replacement

    Individual pins within the 12-way connector can become corroded, bent, or broken over time, disrupting the communication signal between modules. Inspect each pin carefully for physical damage or oxidation.

  3. 03

    Faulty Display Module

    Part replacement

    If the harness and connector check out as good, the Display Module itself may be generating a false reset signal due to internal component failure. This would require board replacement after ruling out wiring issues.

  4. 04

    Failing Motor Control Module

    Part replacement

    In less common cases, the Motor Control Module may be misinterpreting valid signals from the Display Module due to internal degradation. This is typically diagnosed after confirming the harness and Display Module are functioning correctly.

Frequently asked questions about 35

What does 35 mean on a Fisher & Paykel washer?
Error code 35 on a Fisher & Paykel washer indicates a Phase 1 Motor Control Module Reset Error. This means the Display Module sent a false reset signal to the Motor Control Module, causing the washer to stop operation. The fault is most often related to the 12-way wiring harness that connects these two control modules. A technician will inspect the harness connection as the first diagnostic step.
How do I fix error code 35 on my Fisher & Paykel washer?
The first step in fixing error code 35 is to inspect the 12-way harness connection between the Display Module and the Motor Control Module. Check that the connector is fully seated, and look for any corroded, bent, or damaged pins. If the wiring checks out, a qualified technician may need to evaluate whether the Display Module or Motor Control Module requires replacement.
Will resetting my Fisher & Paykel washer clear error code 35?
A power reset may temporarily clear error code 35, but the fault is likely to return if the underlying cause, such as a loose harness connector or a failing control module, is not addressed. Resetting the machine is useful for confirming whether the fault is intermittent, but it should not be treated as a permanent fix. A proper diagnosis of the 12-way harness and control modules is necessary to resolve the issue.
Is it safe to use my Fisher & Paykel washer when error code 35 appears?
It is not recommended to continue operating the washer while error code 35 is active. The fault indicates a communication breakdown between control modules, which can lead to unpredictable motor behavior. Continuing to run the machine without addressing the fault could potentially cause further damage to the Motor Control Module or Display Module.
How much does it cost to repair error code 35 on a Fisher & Paykel washer?
Repair costs for error code 35 vary depending on the root cause. If the issue is a loose or damaged harness connector, the repair may involve only a service call fee, typically in the range of $75 to $150. If a Display Module or Motor Control Module needs replacement, total repair costs including parts and labor can range from $200 to $500 or more depending on parts availability and local labor rates.
