keston 55 boiler

[dferguson]

I'm having a problem with a Keston 55. Its showing code b 26 showing low pressure. How do I increase pressure? The system is connected to the hot water system but I can't identify water inlet other than to hot water and thers no problem with the hot water at the moment. Error code been showing now for 3 days. Been through manuals etc but no joy.

Is your system sealed or open vent?

If it's sealed you'll need to find your filling loop, usually below the red expansion vessel, and top the system up.

If it's open vent, then something is not right with the expansion tank, the cold feed will either be blocked or the ball valve will be shot.

Can anyone help me with my 55. Its showing error code E16. Not in the manulal so have no idea....

makkyh - Anything happening, can the boiler be re-set? Only thing you can do is check that the controls are on, there's enough water in the system and the gas is turned on ... If all that's okay get someone out
