Fisher & Paykel Washer Error Code Err 235

Err 235 means the washer has detected a malfunction in the door lock system. The control board monitors the door lock circuit and expects a resistance of 90 ohms, plus or minus 10 percent, between connector pins CN1-1 and CN2-1. When that reading falls outside the acceptable range, the machine stops and displays Err 235 to prevent unsafe operation.

No, you should not attempt to run the washer while Err 235 is active. The door lock is a safety component that prevents the door from opening during a spin or wash cycle. Operating the machine with a faulty door lock risks water leaking out or the door opening unexpectedly during use.

If the fix is as simple as reseating a connector, there may be no parts cost involved, only your time. A replacement door lock assembly typically costs somewhere in the range of 50 to 150 dollars for the part, depending on the specific model. If professional labor is needed, expect to add 80 to 200 dollars or more for a service call and installation.

Some causes of Err 235 can be addressed without professional help, such as reseating loose connectors or inspecting visible wiring damage. However, accurately diagnosing the fault requires a multimeter to measure resistance between connector pins CN1-1 and CN2-1. If the lock assembly itself has failed, replacing it requires disassembling part of the machine, which is a more advanced repair.

A reset may temporarily clear the error code, but if the underlying door lock fault is still present, the code will return as soon as the washer attempts to lock the door at the start of a cycle. The root cause in the lock assembly, wiring, or connectors needs to be identified and corrected for the error to stay clear.
