Fisher & Paykel Washer Error Code 24

Error code 24 on a Fisher & Paykel washer indicates that the dispensing type has not been configured within the Motor Control Module (MCM). The MCM is a core electronic control component that governs multiple washer functions, including how the dispenser system operates. When the dispensing type parameter is absent or has been cleared from the MCM's memory, the washer cannot properly manage detergent or fabric softener delivery, and this fault code is triggered to alert the technician or user that a required configuration step has not been completed.

This error most commonly appears after the MCM has been replaced, reset, or has lost its stored configuration due to a power-related event. Unlike fault codes that point to a failed component, error 24 is fundamentally a configuration issue: the module is functional, but it is missing a necessary operational setting. The dispensing type setting tells the MCM which type of dispenser is installed or expected, and without it, the washer's control logic cannot proceed correctly with wash cycles that involve dispensing.

The primary corrective action is to reselect the dispensing type using the designated dispensing type setting procedure specific to the Fisher & Paykel model in question. This procedure programs the correct dispensing configuration back into the MCM's memory. If the error reappears after completing the setting procedure, further investigation into the MCM's ability to retain configuration data, or the integrity of the power supply to the module, may be warranted.
