Fisher & Paykel Washer Error Code #40

Error code #40 on a Fisher & Paykel washer indicates a basket disengage fault. This means the floating wash basket has failed to engage or drop into its normal operating position, even though the pressure sensor is reporting that the tub is empty of water. In Fisher & Paykel top-load washers, the basket is designed to float during the spin cycle and then re-engage once water drains. When the control detects that the tub is empty but the basket has still not re-engaged as expected, it throws this fault code to prevent mechanical damage from running the machine in an incorrect state.

The primary suspect when this code appears is the clutch assembly or the pressure tube. The clutch is responsible for mechanically coupling and decoupling the basket during the wash and spin cycles. If the clutch is worn, seized, or obstructed, it may prevent the basket from dropping back into engagement. Separately, the pressure tube connects the tub to the pressure sensor. If this tube is blocked, kinked, or crushed, the pressure sensor may be receiving inaccurate readings, causing the control board to misinterpret the state of the tub even when the basket issue is elsewhere.

In some cases, the basket itself may be physically obstructed by a foreign object, a buildup of detergent residue, or mechanical wear on the basket bearing or suspension components. A thorough inspection of the clutch mechanism, pressure tube routing, and the basket's ability to move freely is essential before replacing any parts. Always disconnect power before inspecting internal components.
