Fisher & Paykel Dishwasher Error Code E6

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.

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.

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.

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.

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.
