What #48 means on a Fisher & Paykel washer

Error code #48 on a Fisher & Paykel washer indicates a fault detected in the hot and/or cold water inlet valve circuit. The water inlet valves are electrically operated solenoid valves that open on command from the control board to allow water into the drum. When the control board cannot properly actuate one or both of these valves, or detects an open circuit condition in the valve wiring, it logs error #48 and halts the cycle to prevent incorrect fill behavior.

The most common electrical cause is an open circuit in the valve solenoid or its associated harness. Each solenoid coil has a specific resistance value, and if the coil burns out or a wire connection fails, the circuit opens and the control board cannot complete the valve activation signal. Harness connectors that are partially seated, corroded, or physically damaged at the valve terminals are also a frequent source of this fault.

Physically, the inlet valves are located at the rear of the machine where the water supply hoses connect. The diagnostic process begins by confirming all harness connectors to the hot and cold valve solenoids are fully and correctly seated. If the wiring checks out, the valve assembly itself should be tested for continuity across each solenoid coil. A coil reading open circuit indicates the valve assembly requires replacement. Both the hot and cold solenoids are typically housed in a single valve body and are often replaced as a unit.

Common causes of #48

  1. 01

    Disconnected or improperly seated valve harness

    Wiring / connection

    The wiring connectors to the hot or cold solenoid valve may not be fully plugged in or may have come loose. Visually inspect and firmly reseat all connectors at the valve body before further testing.

  2. 02

    Open circuit in valve solenoid coil

    Part replacement

    The solenoid coil inside the hot or cold inlet valve can burn out, creating an open circuit the control board cannot complete. Test each solenoid coil with a multimeter set to resistance; an open circuit reading confirms the valve has failed.

  3. 03

    Damaged or broken wire in the valve harness

    Wiring / connection

    A wire in the harness running from the control board to the valve may be broken internally or have a damaged insulation causing an open circuit. Inspect the harness along its full length for pinching, chafing, or visible breaks.

  4. 04

    Corroded valve harness connector terminals

    Wiring / connection

    Moisture in the machine can cause corrosion on the connector pins at the valve, increasing resistance or breaking the circuit entirely. Clean or replace corroded terminals and connectors as needed.

  5. 05

    Faulty water inlet valve assembly

    Part replacement

    If wiring and connections test correctly, the valve body itself may be defective due to a failed solenoid that does not respond to control board signals. Replacement of the inlet valve assembly is required in this case.

Frequently asked questions about #48

What does #48 mean on a Fisher & Paykel washer?
Error #48 indicates a fault with the hot and/or cold water inlet valve circuit. The control board has detected either a wiring issue or an open circuit condition in one of the solenoid valves that controls water flow into the drum. The washer halts the current cycle until the fault is resolved.
How do I fix error #48 on my Fisher & Paykel washer?
Start by checking that all wiring harness connectors to the hot and cold inlet valves are correctly and fully seated at the rear of the machine. If the connections look secure, use a multimeter to test each solenoid coil for continuity. An open circuit reading on either coil means the inlet valve assembly needs to be replaced.
Will resetting my Fisher & Paykel washer clear error #48?
A reset may temporarily clear the error code display, but if the underlying fault in the valve circuit is still present, the code will return when the washer attempts to fill again. A proper repair of the wiring or valve is required to permanently resolve the fault.
Is it safe to keep using my washer when error #48 is showing?
It is not recommended to continue running the washer with this error active. The machine may not fill correctly, which can affect wash performance and potentially cause the control system to behave unpredictably. Resolve the valve fault before resuming normal use.
How much does it cost to fix error #48 on a Fisher & Paykel washer?
If the issue is simply a loose harness connector, there may be no parts cost involved. If the inlet valve assembly needs replacement, parts typically range from $40 to $120 depending on the model, with professional labor adding $80 to $200 on top of that depending on your location and service provider.
