Fisher & Paykel Cooktops F2 Error: Power supply fault
Fisher & Paykel cooktop error code F2 is a high-severity fault meaning Mains power supply voltage fault. F2 indicates the cooktop has detected an unsafe mains voltage condition. F2 clears after a circuit breaker power-cycle if the underlying voltage condition was transient.

Answer to continue safely
Is it safe to keep using?
No. F2 indicates the cooktop has detected an unsafe mains voltage condition. Continuing to operate under abnormal voltage stresses the inverter and power supply components and risks permanent damage. Do not use the cooktop until the supply issue is resolved.
Can I reset the code?
Yes. F2 clears after a circuit breaker power-cycle if the underlying voltage condition was transient. If F2 returns under normal load, the electrical supply requires inspection by a licensed electrician before the cooktop is used again.
When to stop immediately?
Stop if you notice: F2 returns every time multiple zones are activated, Circuit breaker trips alongside the F2 fault.
Symptoms You May Notice
F2 and all zones shut down
The entire cooktop powers off and displays F2; no zones respond to touch inputs.
Fault occurs at full load
F2 appears when multiple high-power induction zones are running simultaneously, particularly on a shared circuit.
Intermittent shutdowns
The cooktop cuts out unpredictably during cooking and restores itself after a short pause.
Possible Causes
Mains voltage out of range
Supply voltage has dropped below or risen above the cooktop's rated input range, triggering the supply protection circuit.
DIY PossibleUndersized or shared circuit
The cooktop is on a circuit shared with other high-draw appliances, causing voltage sag when multiple loads activate simultaneously.
Requires ProfessionalLoose or corroded terminal connection
A loose connection at the cooktop terminal block or junction box creates resistance that causes voltage drop under load.
Requires ProfessionalFaulty internal power supply board
The internal power supply PCB has failed and is reporting a false voltage fault condition.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the cooktop
Switch off the dedicated circuit breaker for the cooktop for 30 seconds, then restore power and check whether F2 clears.
A single transient voltage event will often clear with a power-cycle and not recur.
-
2
Check if fault is load-dependent
Test the cooktop with only one zone active at a low power level. If F2 does not appear, progressively add more zones at higher power to identify whether the fault is load-related.
Load-dependent F2 faults strongly suggest an undersized supply circuit or a loose terminal connection.

3
Inspect the circuit breaker
Confirm the dedicated cooktop circuit breaker is the correct amperage rating as specified in the installation manual. A tripped breaker that resets immediately is a sign of supply issues.
Do not replace a breaker with a higher rating without an electrician confirming the wiring is rated for the increased load.
When to Call a Professional
Contact a qualified technician if:
- Terminal block inspection and tightening requires an electrician in most jurisdictions
- Circuit upgrade to a dedicated higher-amperage supply requires licensed electrical work
- Internal power supply board replacement is a technician-level repair
