What E6 means on a Fisher & Paykel dishwasher

The E6 error code on a Fisher & Paykel dishwasher indicates a fan fault detected by the controller. The sub codes differentiate the nature of the fault: sub code 02 signals an under current condition, meaning the fan motor is drawing less current than expected, while sub code 03 signals an over current condition, meaning the fan is drawing more current than the controller considers safe or normal. The fan in this context is typically the drying or circulation fan responsible for moving air through the tub during the drying cycle.

An under current fault (02) commonly points to an open circuit, a disconnected harness, or a failed fan motor that has lost continuity and is no longer spinning. An over current fault (03) usually suggests a mechanical obstruction blocking the fan blade, a seized bearing in the motor, or a short circuit within the motor windings or wiring harness that is causing excess current draw.

The first diagnostic step is to inspect the wiring harness at both the fan motor connector and the controller board for signs of water intrusion, corrosion, or arcing. Corroded or arc-damaged terminals can alter resistance in the circuit, producing false current readings in either direction. If the connectors check out, the fan motor itself should be tested for continuity and freedom of mechanical rotation before suspecting the controller board.

Common causes of E6

  1. 01

    Corroded or damaged wiring harness connections

    Wiring / connection

    Water damage, corrosion, or arcing at the harness connectors near the fan motor or controller board can disrupt the current signal in either direction. Inspect the connectors closely for green or white corrosion, burn marks, or loose pins.

  2. 02

    Failed or open-circuit fan motor

    Part replacement

    A fan motor that has lost continuity through its windings will draw no current, triggering the under current sub code 02. Test the motor for continuity with a multimeter and check that the shaft spins freely by hand.

  3. 03

    Blocked or seized fan blade

    Wiring / connection

    Debris lodged against the fan blade or a seized motor bearing will restrict rotation and cause excess current draw, triggering the over current sub code 03. Inspect the fan assembly for obstructions and check that the blade turns without resistance.

  4. 04

    Short circuit in the fan motor windings or wiring

    Part replacement

    A shorted motor winding or a chafed wire contacting the chassis can cause abnormally high current draw, producing sub code 03. Check the motor wiring along its entire run for insulation damage or pinch points.

  5. 05

    Faulty controller board

    Part replacement

    If the fan motor, wiring, and connectors all test correctly, the controller board may be misreading the current draw due to a failed sensing circuit. This is the least common cause and should only be considered after all other components are confirmed good.

Frequently asked questions about E6

What does E6 mean on a Fisher & Paykel dishwasher?
E6 indicates a fan fault. Sub code 02 means the fan is drawing less current than expected, pointing to an open circuit or failed motor. Sub code 03 means the fan is drawing more current than normal, pointing to a blockage, seized bearing, or short circuit. The first step is to inspect the wiring harness connections at the fan and controller for corrosion or water damage.
Can I fix the E6 error on my Fisher & Paykel dishwasher myself?
Some causes are DIY-friendly, such as cleaning corroded connector pins or removing a physical obstruction from the fan blade. However, testing motor continuity, tracing wiring faults, and replacing the fan motor or controller board typically require basic electrical knowledge and a multimeter. If you are not comfortable working with appliance wiring, a qualified technician is recommended.
Is it safe to run my dishwasher while the E6 code is active?
It is not advisable to continue running the dishwasher with an active E6 fault. An over current condition in particular indicates the motor may be overloaded, which can generate heat and potentially damage the motor or wiring further. Leaving the fault unaddressed could also result in incomplete drying cycles and moisture-related issues inside the appliance.
How much does it cost to repair an E6 fault on a Fisher & Paykel dishwasher?
Repair costs vary depending on the root cause. Cleaning corroded connectors yourself costs little to nothing. A replacement fan motor typically ranges from around $50 to $150 or more for the part alone, with additional labor costs if a technician is hired. Controller board replacement is generally the most expensive outcome, with parts and labor potentially ranging from $150 to $400 or higher depending on the model.
Will resetting the dishwasher clear the E6 error code?
A reset may temporarily clear the E6 code, but if the underlying fault with the fan motor, wiring, or connections is still present, the error will return as soon as the dishwasher attempts to run the fan again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair. The root cause must be identified and corrected to resolve the error permanently.
