What 68 means on a Fisher & Paykel washer

Error code 68 on a Fisher & Paykel washer indicates a pressure transducer fault where the water level count is reading far above the machine's physical capacity. The pressure transducer is a sensor that monitors water level inside the drum by detecting air pressure changes in a connected hose. When the sensor's output signal exceeds the range the control system expects for a full drum, it triggers this error because the reading is physically impossible for the washer's actual capacity.

The most common causes are a disconnected pressure transducer hose or wiring harness, a damaged sensor that has failed in a high-output state, or a fault within the Motor Control Module itself that is misinterpreting the sensor signal. A disconnected or kinked pressure hose will cause erratic or pegged readings because the air column reference is lost. Similarly, a sensor that has developed an internal short or open fault can output a signal that reads as an impossibly high water level.

Because the first diagnostic step specified for this code is replacement of the Motor Control Module, the fault is considered likely to originate in the module's signal processing circuitry rather than solely in the transducer hardware. However, technicians should inspect the pressure transducer hose connection and sensor wiring harness before condemning the module, as a loose connector or damaged hose is a lower-cost corrective action and may resolve the fault without module replacement.

Common causes of 68

  1. 01

    Disconnected or damaged pressure transducer hose

    Wiring / connection

    The hose that connects the pressure transducer to the drum air chamber can slip off, kink, or crack, causing the sensor to lose its reference and output an out-of-range signal. Inspect the hose along its full length for disconnections, kinks, or splits.

  2. 02

    Faulty Motor Control Module

    Part replacement

    The Motor Control Module may be misinterpreting or generating an erroneous pressure signal even when the transducer and hose are intact. Fisher & Paykel's first diagnostic step for this code is module replacement, indicating the module is a primary suspect.

  3. 03

    Failed pressure transducer sensor

    Part replacement

    The pressure transducer itself can fail internally, producing a signal that reads at or above the maximum possible water level count. A sensor failed in this way will need to be replaced to restore accurate water level detection.

  4. 04

    Loose or corroded wiring harness connector

    Wiring / connection

    A loose or corroded connector at the pressure transducer or at the Motor Control Module can cause the signal line to float to an abnormal voltage, which the module registers as an impossibly high water level count. Check all connectors in the pressure sensor circuit for secure seating and corrosion.

Frequently asked questions about 68

What does 68 mean on a Fisher & Paykel washer?
Error code 68 on a Fisher & Paykel washer is a pressure transducer fault indicating the water level sensor is reporting a count far above what the machine is physically capable of holding. This means the control system cannot trust the water level reading and has halted operation. The cause is typically a disconnected sensor hose, a damaged transducer, or a fault in the Motor Control Module.
Can I fix error code 68 on my Fisher & Paykel washer myself?
A knowledgeable DIYer can start by inspecting the pressure transducer hose for disconnections, kinks, or cracks, and checking that all wiring connectors to the sensor are firmly seated. If the hose and wiring appear intact, the next step is replacing the Motor Control Module, which is a more involved repair that requires comfort with disassembling the washer cabinet and handling electronic components. If you are unsure about module replacement, a qualified technician should perform that step.
Is it safe to use my washer while error code 68 is active?
You should not continue using the washer while error code 68 is active. Because the control system cannot accurately determine the water level in the drum, it cannot properly regulate fill cycles, which risks overfilling and potential water damage to your home. Leave the washer paused or powered off until the fault is diagnosed and corrected.
How much does it cost to repair a Fisher & Paykel washer error code 68?
If the issue is simply a disconnected pressure hose, repair costs are minimal, generally just a service call fee ranging from $75 to $150 if a technician performs the work. If the pressure transducer sensor needs replacement, parts and labor typically range from $100 to $250. Motor Control Module replacement is the most expensive possibility, with parts and labor commonly ranging from $200 to $450 or more depending on the model and region.
Will resetting my Fisher & Paykel washer clear error code 68?
A power reset may temporarily clear the error code display, but the fault will return as soon as the washer attempts another wash cycle and reads the faulty sensor signal again. Error code 68 reflects an underlying hardware problem with the pressure transducer circuit or Motor Control Module, and a reset alone will not correct it. The root cause must be identified and repaired for the code to clear permanently.
