wiring diagram for pressure switch for worcester bosch 350

[Juliepowell]

does anyone actually have an answer that will help me, i am sure that you seem unimpressed with the engineer that i got to help us, however the comments are not going to get my water pressure switch replaced and i did think that this forum would be kind enough to help a member of the public.

sorry feeling rather stressed with lack of ideas

thanks again

Get the part off the numpty and call someone else.

There are only three contacts and ten minutes with a multimeter should be all that is needed.

I am sure if you look closely the circuit diagram will be etched onto the casing of the switch.

Then all you need to do is look a the diagram in the book ,which can be downloaded from WB.

Just looked at the instructions - and 10 minutes is being generous.

As Dan says , just had a quick look myself although the diagram should be on the boiler somewhere.

Brown goes to common but the real headache would be where green/white would terminate , now should green go to NC or NO certainly a trick one for you man.

Brown on common and the other two on the other two.

No water in boiler if it fires then the wires are the wrong way round. who needs a multimeter

Alternatively get a multimeter and test for long and short circuit of the connections

Julie, I think you are being rather rude, and I detect a certain " attitude". Generally a switch is a switch, and regardless of wiring colours, it should be straightforward to change.

As far as not receiving help is concerned, I pointed a means of finding a local guy with experience. Your fitter, if indeed there is one, is clearly not up to it.
