Fisher & Paykel Dishwasher Error Code A6

The A6 code means the dishwasher did not detect spray arm rotation during the wash cycle. This indicates that water is either not reaching the spray arm, the arm is physically obstructed, or there is a mechanical issue with the spray arm seating or the wash impeller. The dishwasher halts the cycle to prevent incomplete washing.

It is not recommended to run cycles while the A6 error is active. The dishwasher is flagging that the spray arm is not functioning, which means dishes will not be properly cleaned or sanitized. Continuing to run cycles without resolving the issue wastes water and energy without effective results.

If the fix involves only cleaning the spray arm jets, clearing obstructions, or reseating the spray arm, there may be no parts cost at all. If the wash impeller needs replacement, parts typically range from $15 to $50 depending on the model, with additional labor costs if a technician is involved. A full service call from a qualified appliance repair technician generally runs between $100 and $200 depending on your location and the extent of the repair.

Start by removing the lower rack and checking that the spray arm is correctly seated on the motor rotor with no wobble. Then confirm the wash impeller is tight on the rotor shaft and not spinning freely. Clear any obstructions that could block spray arm rotation, and clean the spray arm jets and filter assembly. If the impeller is confirmed loose or damaged, it will need to be replaced.

A reset may clear the error code temporarily, but if the underlying cause is not resolved, the A6 code will return once the next wash cycle detects the same problem. A reset is useful for confirming whether the fault was a one-time event, but it is not a substitute for inspecting and correcting the spray arm, impeller, and rotor connection.
