Fisher & Paykel Washer Error Code 104

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.

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.

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.

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.

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.
