What boiler part is this?

Sigh... you all suck.

OP, it's a low pressure switch. Usually used to stop the boiler firing when the system pressure drops below 0.5bar. Also works like a pump proving switch on some boilers IIRC.

If you tell me what boiler it is I can get you a part number, though it's pretty common among various models/manufacturers.

Yeah from the diagram on the back of the pcb cover it is called the pressure switch.

It's a vokera mynute 20e. If I get the part number I can source the part and get my uncle to fit it. He works for british gas but appears he doesn't like to help family too often. I doubt it is this that is making it blow fuses though if it is just a switch.

Oh dear, I see Vokera and British Gas.

Sorry OP, you're doomed!!!!

Pressure switches are an easy swap. If your uncle twists his face then hes a chump!

He works for British Gas, thats alone is a good reason why he should never touch a boiler!

Aye he's a fanny....I already changed a pcb thinking it was that(again no advice/help). I'm hoping to god it is the switch as it doesn't blow fuses with it disconnected.

Vokera make me double facepalm tbh. Utter ****e.
