Alpha hecb33 not firing up

[lwcrs2001]

Hiya guys I had a issue with diverter valve on my combi so I replaced the diaphragm in it. Trouble is my boiler is not firing up now when I call hot water or heating. I am thinking it could be flow switch, if so any way I can test it

nope, have a read of the forum rules

unless your gas safe you cant take the cover off and you cant replace internal parts

no! you cannot test your flow switch or any other part of your boiler and we cannot give you any information about what is wrong with it without you proving that you are GAS SAFE registered by sending a PM to gasman with your registration details. thank you.
