Fisher & Paykel Washer Error Code 86

Error code 86 signals a Phase 2-3 communications error between the display board and the motor controller board. The two boards are not exchanging data correctly, which causes the washer to stop operating. Fisher & Paykel links this fault to the diagnostics outlined under fault code 106 for resolution.

A power reset may temporarily clear the displayed error, but if the underlying wiring or board fault still exists, the code will return once the machine attempts to run a cycle. A reset alone is not a repair and should be followed by proper diagnosis.

Repair costs depend heavily on the root cause. If only a wiring connector needs reseating, the cost can be minimal. If a motor controller or display board requires replacement, parts and labor costs typically range from around $150 to $400 or more depending on parts availability and local labor rates.

Some causes, like a loose wiring connector, can be addressed by a confident DIYer who is comfortable working inside the machine after disconnecting power. However, if the fault lies with the motor controller or display board, board replacement typically requires component sourcing and some technical skill. Referencing the fault code 106 diagnostic steps is the recommended starting point.

The washer will typically stop operation when this error is active, which is the machine protecting itself from uncontrolled behavior. You should not attempt to bypass the fault or force the machine to run until the communications issue has been diagnosed and corrected.
