Fisher & Paykel Washer Error Code 234

Error code 234 indicates a Phase 6 Lid Lock Open Circuit fault. The motor controller has detected that the electrical circuit to the lid lock assembly is broken or not completing properly. This is typically caused by a faulty wiring harness, a loose connector, or damaged terminals between the motor controller and the lid lock. The washer stops as a safety measure because it cannot verify the lid is locked.

No, you should not continue using the washer while this code is active. The lid lock is a critical safety component that prevents the lid from opening during high-speed spin cycles. With an open circuit in the lid lock wiring, the washer cannot confirm the lid is secured, and operating it in this condition could pose a safety risk.

A reset may temporarily clear the code, but if the underlying wiring fault is still present, the error will return as soon as the washer attempts to engage the lid lock again. Resetting the machine does not repair the open circuit in the harness or connectors. A lasting fix requires physically inspecting and repairing or replacing the faulty wiring component.

In many cases, yes. Start by unplugging the washer, then locate the lid lock harness and inspect both connectors at the motor controller and lid lock ends for looseness, corrosion, or bent terminals. Firmly reseat both connectors and test the washer. If the code returns, use a multimeter to perform a continuity check on the harness wires and replace the harness if a break is found.

If the fix is simply reseating a connector, there is no parts cost involved. A replacement lid lock wiring harness typically costs in the range of $20 to $60 for the part. If the lid lock assembly itself has failed and needs replacement, parts can range from $40 to $120. Adding a technician service call will generally bring the total repair cost to somewhere between $100 and $250 depending on your location.
