F.61 on a Vaillant ecoTEC means the boiler has found a fault in how it controls the gas valve. The valve opens and closes the gas to the burner. If the control signal is not right, the boiler stops.
The cause can be the gas valve itself, its wiring, or the circuit board that drives it. Damp affecting the electrics is another possibility. Your manual will confirm the meaning for your model.
Vaillant boilers are common in Wednesbury, from the semis around Wood Green to the homes near Friar Park. Many are now ten or more years old, which is when gas valves and boards begin to show their age.
Turn the boiler off at the switch, wait a minute, turn it back on and reset once.
Mention any water leak near or above the boiler. Water on the electrics is a known cause.
Gas valves must only be worked on by a registered gas engineer. There is nothing to adjust yourself.
The gas valve, its lead and the board. They test before replacing anything, so you only pay for the part that has failed.
A photo of F.61, the boiler label, and whether the code appeared suddenly or after a leak.
No. It is a control fault, and the boiler has shut off safely. A gas smell is different from a fault code. If you notice one, step outside, avoid switches and ring 0800 111 999, the gas emergency line.
It can be either. Testing tells which, and the cheaper part is checked first.
Not while F.61 shows. Leave it off until it has been checked.
