Diverter valve fault

Fisher & Paykel codesFisher & Paykel washer codes

Diverter valve fault - wash water is not circulating correctly in the re-circulation hose.

First step from the service manual

Check that diverter valve is directing water flow to the correct hose; check for blockage, wiring fault, or Motor Control Module fault; check hoses for leaks and check resistance of diverter valve.

What #52 means on a Fisher & Paykel washer

Error code #52 on a Fisher & Paykel washer indicates a diverter valve fault, specifically that wash water is not circulating correctly through the recirculation hose. The diverter valve is an electrically actuated component responsible for directing water flow between different hose paths during the wash cycle. When the machine detects that water is not moving through the recirculation circuit as expected, it logs this fault and typically halts or interrupts the cycle to prevent wash performance issues or potential water handling problems.

The diverter valve operates under the control of the Motor Control Module, which monitors water routing and actuates the valve accordingly. A fault can stem from several sources: the valve itself may have failed electrically, presenting an out-of-range resistance value when measured; the wiring harness connecting the valve to the control module may have a break, short, or loose connector; or the Motor Control Module may be failing to send the correct signal to actuate the valve. Physical blockages in the recirculation hose or the valve body itself can also prevent correct water flow even when the valve is electrically functional.

Diagnosing this fault requires a systematic approach. Technicians should first visually confirm the diverter valve is physically directing flow to the correct hose and inspect all associated hoses for kinks, blockages, or leaks. Electrical testing of the valve coil resistance should follow, comparing measured values against specification. If wiring and the valve itself test within range, attention should shift to the Motor Control Module as the source of the fault signal.

Common causes of #52

  1. 01

    Diverter Valve Electrical Failure

    Part replacement

    The diverter valve coil can fail internally, producing an incorrect resistance reading or no continuity at all. Testing the valve's resistance with a multimeter will confirm whether the coil is within specification.

  2. 02

    Blocked Recirculation Hose

    Wiring / connection

    Lint, debris, or a kink in the recirculation hose can restrict or stop water flow entirely, triggering this fault even if the valve is electrically healthy. Inspect the hose along its full length for obstructions or sharp bends.

  3. 03

    Wiring Fault or Loose Connector

    Wiring / connection

    A broken wire, corroded terminal, or disconnected connector between the Motor Control Module and the diverter valve can prevent the valve from actuating correctly. Inspect the wiring harness and connectors at both ends for visible damage or looseness.

  4. 04

    Hose Leak at Diverter Valve

    Wiring / connection

    A leak at the diverter valve connection points or along the recirculation hose can reduce water pressure in the circuit enough to trigger the fault. Check all hose clamps and connection points for moisture or dripping.

  5. 05

    Motor Control Module Fault

    Part replacement

    If the diverter valve, hoses, and wiring all test correctly, the Motor Control Module itself may be failing to actuate or monitor the valve properly. This is the least common cause and should be investigated only after other components are ruled out.

Frequently asked questions about #52

What does #52 mean on a Fisher & Paykel washer?
Error code #52 on a Fisher & Paykel washer indicates a diverter valve fault, meaning the machine has detected that wash water is not circulating correctly through the recirculation hose. The diverter valve is responsible for directing water to the correct hose path during the wash cycle. The fault can be caused by a failed valve, a blocked or leaking hose, a wiring issue, or a Motor Control Module problem. The washer will interrupt the cycle until the underlying cause is resolved.
Can I fix error code #52 on my Fisher & Paykel washer myself?
Some causes of error #52 are accessible to a knowledgeable DIYer, such as checking for a kinked or blocked recirculation hose or inspecting wiring connectors for looseness or corrosion. However, testing the diverter valve's resistance and diagnosing the Motor Control Module requires a multimeter and some familiarity with appliance electrical systems. If you are not comfortable working with electrical components, a qualified technician should perform the diagnosis.
Is it safe to keep using my washer when error #52 is showing?
It is not recommended to continue running the washer while this fault is active. The error indicates water is not being directed correctly, which can lead to poor wash performance and potential water leakage depending on the cause. Running the machine repeatedly in this condition could worsen a hose leak or cause further damage to the valve or control module. Address the fault before resuming normal use.
How much does it cost to repair a diverter valve fault on a Fisher & Paykel washer?
Repair costs depend on the root cause. Clearing a blocked hose or reseating a loose connector costs little to nothing if done yourself. Replacing the diverter valve typically falls in the range of $80 to $200 including parts and labor, depending on your location and service rates. A Motor Control Module replacement is a more significant repair, often ranging from $200 to $450 or more for parts and labor combined.
Will resetting my Fisher & Paykel washer clear error code #52?
Resetting the washer may temporarily clear the error code display, but if the underlying fault is still present, the code will return once the machine runs through the affected part of the cycle again. A reset is not a fix for this error. The diverter valve, hoses, wiring, and Motor Control Module should all be inspected and tested to identify and correct the actual cause before the machine is returned to regular use.
