What 104 means on a Fisher & Paykel washer

Error code 104 on a Fisher & Paykel washer indicates a communications failure between the Display module and the Motor Controller, specifically occurring during phases 2 through 6 of the communication sequence. The Display module and Motor Controller rely on a continuous data exchange to coordinate wash cycle operation. When that communication link is interrupted or degraded during the specified phases, the machine cannot proceed safely and logs this fault. For additional diagnostic context, Fisher & Paykel references fault code 106 alongside this error, suggesting overlapping or related communication faults may also be present.

The root cause of this error is most commonly traced to the Display module itself rather than the Motor Controller. Because the Display module initiates and manages the communication sequence, a failed or corrupted module is the primary suspect when this fault appears. Wiring harnesses connecting the two modules can also contribute if connectors are loose, corroded, or damaged, interrupting the signal during active phases. In rarer cases, a failed Motor Controller may be unable to respond correctly to Display module communication attempts, producing the same fault code.

Diagnosis should begin with a replacement of the Display module, as directed by the first diagnostic step. If swapping the Display module does not clear the fault, technicians should inspect the wiring harness between the two modules for continuity and connector integrity before concluding the Motor Controller is at fault. Reviewing any concurrent fault code 106 is also recommended to build a complete picture of the communication failure.

Common causes of 104

  1. 01

    Failed Display Module

    Part replacement

    The Display module is the primary suspect for error 104 and is the first component recommended for replacement. An internally failed or corrupted Display module cannot complete the required communication sequence with the Motor Controller across phases 2 through 6.

  2. 02

    Loose or Damaged Wiring Harness

    Wiring / connection

    The wiring harness connecting the Display module to the Motor Controller can develop loose connectors, corrosion, or physical damage that disrupts the communication signal. Inspect all connectors between the two modules for secure seating and visible damage.

  3. 03

    Corroded or Intermittent Connector Contacts

    Wiring / connection

    Moisture exposure can cause oxidation on the connector pins between the Display module and Motor Controller, creating high-resistance or intermittent connections that break down during active communication phases. Cleaning and reseating connectors may resolve this without part replacement.

  4. 04

    Failed Motor Controller

    Part replacement

    If replacing the Display module and verifying wiring integrity does not resolve error 104, the Motor Controller may be unable to respond to communication attempts from the Display module. This is a less common cause but should be evaluated after ruling out the Display module and wiring.

Frequently asked questions about 104

What does 104 mean on a Fisher & Paykel washer?
Error code 104 means the washer has detected a communications failure between the Display module and the Motor Controller during phases 2 through 6 of their communication sequence. This prevents the washer from operating normally. Fisher & Paykel also links this error to fault code 106, so both codes should be reviewed together. The Display module is the first component to replace when diagnosing this fault.
Can I fix error code 104 on my Fisher & Paykel washer myself?
A knowledgeable DIYer can attempt to resolve this by first inspecting and reseating the wiring harness connectors between the Display module and Motor Controller. If that does not clear the fault, replacing the Display module is the recommended next step. Replacing the Motor Controller is more complex and may be better handled by a qualified technician if the Display module swap does not resolve the issue.
Will resetting my Fisher & Paykel washer clear error code 104?
A power reset may temporarily clear the error display, but if the underlying communication fault between the Display module and Motor Controller persists, the code will return once the washer attempts to operate again. A reset alone is not a fix for this fault. The hardware cause must be identified and corrected to prevent the code from reappearing.
Is it safe to use my Fisher & Paykel washer with error code 104 active?
It is not advisable to continue using the washer while error code 104 is active. The communication failure between the Display module and Motor Controller means the machine cannot properly coordinate its operating cycle, which could result in incomplete cycles or unpredictable behavior. The fault should be diagnosed and repaired before the washer is returned to regular use.
How much does it cost to repair error code 104 on a Fisher & Paykel washer?
Repair costs depend on which component is at fault. If the fix involves only inspecting and reseating wiring connectors, costs may be minimal beyond a service call fee, typically in the range of $75 to $150. Replacing the Display module will add the cost of the part, generally ranging from $100 to $250 depending on the model. If the Motor Controller also requires replacement, total repair costs could range from $200 to $450 or more including labor.
