Fisher & Paykel Washer 42 Error Code: Rotor Fault

One of the briefest entries

The manual describes code 42 in one idea: on Phase 1, the Motor Controller received some confusing information as feedback, and it files this as a rotor fault. Nothing in the entry points to a specific component.

The single listed action

1. Power the Smartdrive down at the wall socket.
2. Count to 5 seconds and switch it back on.
3. Start the washer again.

The entry ends there, with no part to replace, nothing to inspect in the wiring, and no secondary source.

If the fault comes back

The manual states no cause. If 42 shows again after the power cycle, the next move is professional diagnosis rather than the replacement of some part on a hunch.

Confirming the last fault

One level in the manual’s diagnostic table shows the code of the last fault, as long as it occurred inside the previous 8 cycles. A technician can use it to verify that 42 was really the last fault, in line with the booklet, which says a fault should be confirmed before anyone acts.

Codes that do name rotor or motor parts

• Code 53: the rotor position sensor failed its step test; wiring and sensor checks follow.
• Code 54: the motor step test detected no current.
• Code 55: a system step fail that points to the rotor position sensor.
