Fisher & Paykel Refrigerator Error Code 33

Solenoid Driver 2 has failed

Fisher & Paykel codesFisher & Paykel refrigerator codes

Solenoid Driver 2 has failed. Solenoid Driver 1 may still be operational and the water dispenser is still working.

First step from the service manual

Check the solenoid resistance. If not within limits, replace the solenoid. If OK, replace the display module.

What 33 means on a Fisher & Paykel refrigerator

Error code 33 on a Fisher & Paykel refrigerator indicates a failure in Solenoid Driver 2, one of two solenoid driver circuits housed within the display module. Solenoid drivers are electronic control circuits responsible for energizing solenoid valves, which regulate water flow within the refrigerator's water and ice dispenser system. When Driver 2 fails, the display module can no longer reliably control the solenoid valve assigned to that circuit. Importantly, Solenoid Driver 1 may remain fully operational, meaning the water dispenser itself can often continue to function during this fault condition.

The diagnostic process for error code 33 begins with measuring the resistance of the solenoid connected to Driver 2. If the solenoid's resistance falls outside acceptable limits, the solenoid coil itself is the likely point of failure and should be replaced. A solenoid with shorted or open windings can draw abnormal current through the driver circuit, which can damage the driver. If the solenoid resistance tests within specification, the fault lies within the display module itself, specifically the Driver 2 output circuit, and the display module will need to be replaced.

Common causes of this fault include a failed solenoid valve coil, wiring issues between the solenoid and the display module, or an internal failure of the display module's driver circuitry. Moisture intrusion or prolonged electrical stress on the driver output can degrade the driver over time. Because the water dispenser may still function through Driver 1, this code can sometimes go unnoticed until a related dispenser function stops working entirely.

Common causes of 33

  1. 01

    Failed solenoid valve coil

    Part replacement

    The solenoid coil assigned to Driver 2 may have developed an open or short circuit, causing its resistance to fall outside acceptable limits. This is the first component to test and is the most common root cause of this fault.

  2. 02

    Internal display module driver failure

    Part replacement

    If the solenoid tests within resistance specifications, the Driver 2 circuit inside the display module has failed internally. This can result from electrical stress, heat, or component aging within the module.

  3. 03

    Wiring harness fault between solenoid and display module

    Wiring / connection

    Damaged, corroded, or loose wiring between the solenoid valve and the display module can cause the driver circuit to read an incorrect load, triggering the fault code. Inspect connectors and wire insulation for damage.

  4. 04

    Moisture or corrosion on connector terminals

    Wiring / connection

    Water exposure near the solenoid or display module connections can cause corrosion that increases resistance or causes intermittent shorts, leading to a Driver 2 fault reading.

Frequently asked questions about 33

What does 33 mean on a Fisher & Paykel refrigerator?
Error code 33 means that Solenoid Driver 2 inside the display module has failed. This driver circuit is responsible for controlling a solenoid valve in the water dispenser system. Solenoid Driver 1 may still be working, so the water dispenser could continue to operate normally. The fault requires diagnosis of the solenoid valve and potentially the display module.
Can I fix error code 33 on my Fisher & Paykel refrigerator myself?
A knowledgeable DIYer can start by testing the resistance of the solenoid valve connected to Driver 2. If the resistance is out of specification, replacing the solenoid valve is the recommended fix. If the solenoid tests fine, the display module itself needs to be replaced, which is a more involved repair but still within reach for someone comfortable working with appliance electronics.
Will resetting my Fisher & Paykel refrigerator clear error code 33?
A reset may temporarily clear the error code from the display, but if the underlying fault in the solenoid or display module has not been corrected, the code will return. Resetting should only be used as part of confirming a repair, not as a standalone fix. The root cause must be diagnosed and resolved to permanently clear the fault.
Is error code 33 on a Fisher & Paykel refrigerator a safety concern?
Error code 33 does not typically represent a safety hazard. The fault is contained to the solenoid driver circuit and affects water dispensing functions rather than refrigeration or food safety. However, leaving the fault unaddressed could eventually impact dispenser performance, so timely repair is still recommended.
How much does it cost to repair error code 33 on a Fisher & Paykel refrigerator?
Repair costs depend on which component has failed. Replacing a solenoid valve is generally less expensive, with parts typically ranging from around $20 to $80 depending on the model, plus any labor costs. If the display module needs replacement, parts can range from roughly $100 to $250 or more, with additional labor if a technician is involved. Getting a diagnostic assessment first will help clarify the exact repair needed.
