Error F.60

Safety first:

1) If you smell gas: do not operate any switches or the boiler. Evacuate the property immediately and call your gas emergency number. Do not attempt any repairs.

2) Always isolate electrical power to the boiler before removing panels or touching any internal components. If you are not competent working around live electrical equipment or gas appliances, stop and call a Gas Safe engineer.

Initial homeowner checks (non-invasive):

1) Note when the fault appears: during start-up, during running, or intermittently. Record any accompanying codes or LEDs.

2) Try a normal reset using the boiler’s reset/knob procedure per the user manual. If a one-off transient caused it, the fault may clear, but do not keep resetting repeatedly.

3) Check the household gas supply: confirm other gas appliances (hob, cooker) work and the gas meter isolation tap is fully on. If no gas supply, contact your gas supplier.

4) Check mains power and fused spur to the boiler. Ensure the boiler has mains power and any external programmer/stat is calling for heat if appropriate.

5) Check boiler pressure gauge is within the normal range (usually around 1–1.5 bar cold). Very low or very high pressure can cause other faults; top up only if you know the filling procedure.

Visible inspection you can safely carry out:

1) With the boiler isolated and power off, remove the outer case only if you are comfortable doing so and it does not void warranty. Look for obvious signs of damage around the wiring loom to the gas valve: burned insulation, melted connectors, water corrosion, or rodent chew marks. Do not touch bare terminals.

2) Inspect the PCB visually for burned components, bulging capacitors, or scorch marks. Take photos for the engineer.

3) Check that connectors between the gas valve loom and the PCB are fully seated (only if you are confident and have power isolated while re-seating). Do not attempt to test voltages or operate the valve unless qualified.

What not to do as a homeowner:

1) Do not attempt to dismantle or repair the gas valve or the PCB. Gas valves and control electronics are safety-critical and must be serviced or replaced by a Gas Safe engineer.

2) Do not attempt live electrical voltage checks unless you are trained and competent.

When to call a professional and what they will do:

1) Call a Gas Safe registered engineer if the error persists after the simple checks, if you found damaged wiring, or if there are any signs of burning or water ingress. Provide the engineer with the boiler model, serial number, the exact error code (F.60), the conditions when it appears, and any photos you took.

2) The engineer will perform proper electrical and gas-safety diagnostics: measure control voltages to the gas valve, check continuity and insulation of the loom, test the gas valve operation, and interrogate/replace the PCB if required. They can also check ignition electrodes, flame detection, and other related components that might cause the control to report a gas-valve fault.

3) Any repairs involving the gas valve assembly, replacement of the wiring loom, or PCB repairs/replacement should only be performed by a Gas Safe engineer. After repair they will run safety and combustion checks, and verify the boiler is operating correctly and safely.

Final notes:

1) Keep a record of when the fault occurred and any actions taken (resets, checks, photos). That helps the engineer diagnose faster.

2) Because F.60 relates to gas control, treat it as a priority safety issue and arrange a professional visit rather than attempting internal repairs yourself.
