Fisher & Paykel Washer Error Code 112

Error code 112 on a Fisher & Paykel washer indicates that the motor current sense circuit has detected an unrealistically high current level sustained for more than 2 seconds. The motor control module continuously monitors the electrical current flowing through the drive motor during operation. When that current spikes to an abnormal level and remains there, the control module registers this as a fault condition and halts the cycle to prevent component damage.

This type of fault typically points to one of two root causes: a problem within the motor control module itself, or a condition in the drive motor or its wiring that is causing excessive current draw. A failing motor with shorted windings, a seized bearing, or a mechanical obstruction in the drum can all force the motor to draw far more current than normal. Similarly, a fault in the motor control module's current sensing circuitry can produce a false high-current reading even when the motor itself is operating correctly.

Because the primary diagnostic step is replacement of the motor control module, the module is considered the most likely point of failure. However, technicians should also inspect the drive motor for signs of mechanical binding or winding damage before condemning the module entirely. Checking the wiring harness between the motor and the control module for shorts or damaged insulation is also a worthwhile step prior to part replacement.
