Will my Potterton 80E explode if I disconnect the Water Pressure Switch?

because the boiler fires and works fine when I've disconnected the switch,

dirty and my wife is upset!

Not for more than is absolutely necessary, so get a new one quickly.

Thanks for the reply. My question is really, would it be OK to leave it on for, say, 2 days?

And what risks am I taking in doing so?

Any help gratefully accepted.

If it is only for a couple of days, or a week or so, then you won't really effect anything. Just keep an eye on it and make sure the system is not bubbling and making weird and wonderful noises. But the device is there for safety reasons, so it is not recommended to leave it off line for prolonged periods of running the system. The ideal situation is to order the part and make sure it is going to arrive before you do the workaround of removing the faulty one.

This switch is a low pressure switch. The pressure releif valve is what stops the boiler exploding. However if you toast your boilerif there is no water in it - as you have disconnected the switch - then that will be your loss.
