Fisher & Paykel SmartDrive Code 43: out-of-Balance switch signal problem

What 43 means

Code 43 on Fisher & Paykel SmartDrive Phase 1 to 6 top-load washers means an out-of-balance switch error. The signal coming from the out-of-balance switch indicates that the switch itself is not working properly, so the washer cannot judge whether the load is unbalanced during spin. The cycle stops and the display shows 43. A technician can check the switch and its wiring.

Common causes of 43

Out-of-balance switch giving an incorrect signal
Out-of-balance switch wiring or connector problem
Control not reading the switch correctly

✓ One safe check you can try

1. Pause the cycle, open the lid once the basket stops, and spread the clothes evenly. 2. Check that the washer sits level. 3. Switch off the breaker for one minute and restore power. 4. If 43 comes back with an even, small load, call us.

! Why to stop there

The switch is mounted under the top housing and tied to the suspension.
A load that is merely uneven gives a different message, so 43 points to the switch path.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

4343 questions

Is 43 the same as an unbalanced load?

No. An unbalanced load gives a balance warning. Code 43 says the out-of-balance switch itself is sending a signal that cannot be trusted. The balance switch is its own part.

Why does the washer stop during spin?

Without a trusted balance signal, the washer cannot spin at speed safely, so it halts the cycle. Balanced spinning is what protects the cabinet and drive.

Will leveling the washer fix it?

Leveling and an even load are worth a try. If 43 remains, the switch or its wiring needs a technician. If 43 stays, the switch or wiring is the next suspect.
