Fisher & Paykel Washer Error Code 28

Error code 28 means the Display Module and Motor Control Module are running out of sequence with each other during Phase 1 of their communication protocol. This inter-module synchronization failure prevents the washer from operating correctly. The diagnostic procedure follows the same steps as fault code 17, focusing on wiring, connectors, and module condition.

A power reset by unplugging the machine for a few minutes may temporarily clear code 28 if the fault was caused by a transient power disruption. However, if there is an underlying hardware issue such as a damaged wire or failing module, the error will return once the machine attempts to run through the affected phase again. A reset alone is not a fix for persistent error 28.

Repair costs depend on the root cause identified during diagnosis. If the issue is a wiring connector or harness repair, labor costs alone might range from around $80 to $150. If a Display Module or Motor Control Module requires replacement, total costs including parts and labor could range from $200 to $500 or more, depending on parts availability and local service rates.

Some causes of error code 28, such as a loose connector or a transient power glitch, can be addressed without specialized tools. You can start by unplugging the washer, inspecting all visible wiring and connectors between the control modules, and reseating any loose connections. However, if the fault points to a damaged harness or a failed module, professional repair or component replacement is recommended.

It is not advisable to continue operating the washer while error code 28 is active. The fault indicates that critical control modules are not communicating properly, which means the machine cannot reliably manage the wash cycle or motor operation. Running the washer in this condition could worsen the fault or create additional electrical stress on the components.
