Whirlpool®
What this codemay mean.
A plain-language reading of the code — always confirm against your model’s documentation.
Mean
The oven is most often wired incorrectly at the home electrical supply or the hard-wire connection.
F9 and F9 E0 are one and the same message: the manual says it will most often indicate incorrect wiring at the home electrical supply or at the hard-wire connection.
Was the oven installed correctly? Each terminal has to be wired correctly, with L2 and N not swapped. The manual says to contact a qualified electrician to verify the electrical supply.
Then reset power
If power was lost, line noise detected by the control as an incorrect voltage can bring up F9, F9 E0 or PF.
Keys pressed within the 10-second delay at power-up can also trigger it.
Shut off the breaker(s) for one minute, switch them on, and monitor the oven for one minute so the code does not return.
Verify oven operation.
Applies to: wall ovens.
