Baxi Gas Valve 225959

The Baxi gas valve, part number 225959, is the gas control component fitted to Baxi Solo WM series boilers. It sits on the gas train and regulates the supply of gas to the burner, opening and closing on demand from the boiler controls and modulating flow to match the heat requirement of the system. It is a serviceable item, so it is replaced as a complete unit rather than repaired on site.

• The burner fails to light, or lights and then drops out shortly after ignition.
• The boiler locks out repeatedly with an ignition or flame supervision fault.
• Flame height or burner pressure cannot be set or held steady during a service.
• Gas flow is intermittent, giving erratic heating and hot water performance.
• The valve body shows signs of leakage, contamination or mechanical damage.

• Confirm the boiler model and GC number against the compatibility list, as the Solo WM range uses several variants.
• Check the existing valve against part number 225959 and alternative number 1111562 before ordering.
• Inspect the gas train seals and washers at the same time and renew them if they are disturbed during removal.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
