What the cooktop is detecting
At power-up the control checks the supply connection. A pattern that only a wiring error can produce sets F9E0.
Causes listed for this condition
In the order the service documentation checks them. Documented causes come from the manufacturer's service documentation for these platforms; possible causes are based on how the system works; unconfirmed marks common assumptions that the documentation does not support.
- Documented Neutral connected in place of L2 (or similar) at the cooktop's supply connection.
- Possible A wiring fault inside the cooktop.
Safe checks you can make
- If the cooktop was recently installed or had electrical work done, tell the installer or an electrician about the code, because it concerns the power connection.
This stage requires professional testing. Full diagnosis involves hazards such as live line voltage, gas, a sealed refrigerant system or microwave high voltage. Do not attempt it yourself.
What a technician checks
- This requires professional testing: verifying the supply means measuring live 240-volt circuits.
- Compares the connection with the installation instructions.
Can you keep using it?
Stop using it until it is checked. Do not use the appliance until the power connection is checked by a qualified technician or electrician. A reversed or missing supply conductor can leave parts energized that should not be.

Repair or replace?
A fault code alone rarely justifies replacing a cooktop. Most F9E0 repairs involve a single component once diagnosed. Replacement becomes worth considering when the unit is near the end of its typical 13–17-year life and the diagnosed repair is a major one. See the repair-or-replace guide.
