Fisher & Paykel Washer Error Code #9

Error #9 means the washer's current machine size setting does not match the value stored in its control memory. This mismatch prevents the machine from operating correctly, as the controller uses the machine size parameter to regulate water fill and cycle behavior. The error is typically resolved by performing the Machine Size Setting procedure using a specific button sequence. No parts are usually required unless the control board itself is faulty.

It is not recommended to run the washer while error #9 is active. Because the machine size setting is used to calibrate water levels and cycle timing, operating with a mismatched configuration could result in incorrect fill amounts or improper cycle behavior. The fix is straightforward and should be completed before resuming normal use.

In most cases, error #9 can be resolved at no parts cost by performing the Machine Size Setting button sequence yourself. If a service technician is needed to perform the procedure, you could expect a diagnostic or service call fee in the range of $75 to $150 depending on your location. If the control board has failed and needs replacement, parts and labor could range from $200 to $450 or more depending on the specific model and part availability.

To fix error #9, perform the Machine Size Setting procedure: press and hold the WASH TEMP UP button, then press the POWER button, then press the SPIN SPEED UP button until the Hold LED turns on, and finally press the POWER button to return to normal operation. This reprograms the correct machine size into the controller's memory and should clear the fault. If the error returns after completing this procedure, the control board may need further inspection or replacement.

A standard power reset alone will not clear error #9, because the underlying cause is a mismatch between the active setting and the stored memory value. Simply cutting power and restoring it does not rewrite the memory. You need to perform the specific Machine Size Setting procedure using the WASH TEMP UP, POWER, and SPIN SPEED UP buttons as described to properly resolve the fault.
