What 43 means on a Fisher & Paykel washer dishwasher oven
Error code 43 on a Fisher & Paykel washer indicates an out of balance switch fault. This switch is a mechanical or electromechanical sensor designed to detect when the drum or load has shifted to a point that could cause excessive vibration or mechanical stress during the spin cycle. When the control board receives a signal from this switch indicating an imbalance condition, or when it detects an unexpected or continuous signal from the switch circuit, it triggers error code 43 and typically halts the spin cycle to prevent damage to internal components.
The out of balance switch itself is usually positioned near the suspension system of the drum assembly. It may be a contact-type switch that trips physically when the drum displaces beyond a set threshold, or it may be integrated into the motor or suspension monitoring circuit. A fault can arise from the switch being stuck in the tripped position, a wiring harness issue such as a broken or shorted wire leading to the switch, or a faulty switch that no longer returns accurate feedback to the control board.
Actual load distribution inside the drum is also a common contributing factor. Heavy or bulky items like blankets or towels can shift during the cycle and physically trigger the switch repeatedly, causing the machine to log this fault. In these cases the fault may clear once the load is redistributed. However, if the error persists across multiple loads, the switch itself, its wiring, or the suspension components holding the drum in proper alignment should be inspected closely.

Common causes of 43
- 01
Unbalanced laundry load
Wiring / connectionHeavy or bulky items can clump on one side of the drum during a spin cycle, physically triggering the out of balance switch. Open the door, redistribute the load evenly, and restart the cycle to see if the error clears.
- 02
Faulty out of balance switch
Part replacementThe switch itself may be stuck in a tripped position or may have failed internally, causing it to send a constant fault signal to the control board regardless of actual drum balance. Replacing the switch is typically required in this scenario.
- 03
Wiring harness fault
Part replacementA broken, corroded, or shorted wire in the harness connecting the out of balance switch to the control board can produce a false fault signal. Inspect the harness for visible damage, loose connectors, or chafing near moving components.
- 04
Worn or damaged suspension components
Part replacementIf the drum suspension rods, springs, or dampers have deteriorated, the drum may shift excessively during spin and repeatedly trigger the switch even with a properly sized load. Inspect all suspension components for wear, breakage, or loss of tension.
- 05
Control board fault
Part replacementIn less common cases, the main control board may misinterpret or fail to correctly process the signal from the out of balance switch circuit, logging error 43 even when the switch and wiring are in good condition. This is typically diagnosed after all other components have been ruled out.
