Fisher & Paykel Washer Error Code 250

Error code 250 on a Fisher & Paykel washer indicates a SmartPump loss of synchronization event. The SmartPump is a brushless DC motor-driven drain pump that relies on precise timing signals to spin the impeller. When the control board attempts to start the pump and cannot establish or maintain synchronization with the rotor, it interprets this as a motor stall condition and triggers error 250. This typically means the pump rotor is physically prevented from spinning rather than having failed electrically.

The most common root cause is a foreign object lodged under or on top of the impeller, blocking rotation. Small items such as coins, buttons, hair ties, or debris that pass through the drum can collect in the pump housing and jam the impeller. Because the motor cannot overcome the mechanical resistance, it stalls at startup and the inverter loses sync with the rotor position. This is a mechanical obstruction problem in the majority of cases, not an electrical fault.

When diagnosing this code, the first electrical check is measuring the resistance of the pump stator windings. Each phase should measure 8.1 ohms plus or minus 10%, and any two phases measured across each other should read 16.2 ohms plus or minus 10%. Readings outside these ranges indicate a damaged stator winding. If the stator measures within spec, the focus should shift to physical inspection of the impeller and pump chamber for obstructions before considering pump replacement.
