Fisher & Paykel Washer Error Code 58

Error code 58 indicates a pressure transducer maximum adjustment fault. The Display Module checks memory at startup and finds a pressure transducer count value that is greater than expected. This points to a problem with how the Motor Controller Module is storing or processing water level data. The recommended first step is to replace the Motor Controller Module.

A basic power reset is unlikely to permanently clear error code 58. Because the fault is tied to a count value stored in the Motor Controller Module's memory, the Display Module will likely detect the same out-of-range value again on the next startup. The underlying hardware issue needs to be addressed before the fault will stay cleared.

Repair costs depend on whether the Motor Controller Module, the pressure transducer, or both components need to be replaced. Parts alone for a Motor Controller Module on Fisher & Paykel washers typically range from around $150 to $350 or more depending on the model. Adding professional labor, total repair costs commonly fall in the range of $250 to $550. Getting a quote from a certified technician before proceeding is a good idea.

A knowledgeable DIYer can inspect the wiring and connectors between the pressure transducer and the Motor Controller Module for obvious damage or loose connections. However, if those checks do not resolve the issue, the fix requires replacing the Motor Controller Module, which involves working with control board components and wiring harnesses. If you are not comfortable with appliance electronics, a qualified technician is recommended.

It is not advisable to continue using the washer while code 58 is active. The pressure transducer is responsible for monitoring water levels, and a fault in that system could result in incorrect water fill levels during a cycle. Running the washer in this condition risks improper operation and potential water-related issues.
