Fault codes related to this part (not the entire boiler). They usually have more possible causes: first rule out electrodes, wiring/connections, and gas supply. Verified with ≥3 sources.

CodeWhat does it mean?Cause and diagnosis (this part)
F.61Fault: gas valve control.The gas valve (coils/actuation) is not responding or is short-circuited, so the electronics cannot actuate it. Check the resistance/insulation of the coils and the presence of control voltage during the ignition attempt; verify that it opens by measuring pressure at the outlet port.
F.62Error: gas valve disconnection controller.The valve does not close in time or is not sealed (delayed closure/internal leak), so the flame signal persists after shutdown. Check for tightness and closure with a leak/pressure drop test and ensure that the ionisation signal disappears immediately when the gas is cut off.
F.28Start-up fault: ignition failed.If the gas valve does not open or modulate, the burner does not receive gas and ignition fails. Check the control voltage at the valve during attempts and measure inlet/outlet pressures with a manometer to rule out a fault in the gas block.
F.27Safety shutdown: flame simulation.Internal leak of the solenoid valve (does not close completely) allows gas to pass when it should be closed, and the sensor detects 'flame' out of sequence. Check valve tightness/closure with a leak test and observe ionisation current at rest.
How do I know if this gas valve is the one for my boiler?
Verify the reference 56019 printed and ensure your model is on the list of compatible ones; also compare the connections with the original part. It is a Honeywell piece.
What is it used for?
The gas valve regulates and modulates the gas flow to the burner.
Ignition faults, does not modulate, or smells of gas?
It could be the gas valve. IMPORTANT: gas handling ONLY by an authorised technician.
Which models is it suitable for?
Part shared by various models (see Compatibility). If your model does not appear, send us a photo of the marking and we will confirm it.
Installation and recommendations
Installation and pressure adjustment by authorised technician; mandatory leak check.
What does refurbished mean and what coverage does it have?
Part removed from a boiler out of service, inspected and tested. Includes 1-year warranty and 14-day return policy. Delivery within 2–4 working days in the EU.
