Hello, so far it sounds like either the water flow switch is not closing or the high temperature safety cut out switch inside the boiler with a red reset button on it has tripped.

If you can take a close up, exceedingly well focused photo of the wiring diagram glued to the inside of the boiler service access panel and attach it here using the 'add files' link next to your send button, I will mark it up with trouble shooting instructions.

You may need a multi meter to do a few tests.

.

I will be out of the office a little later this morning, for about 2 hours, if I miss you and you want faster service just 'opt the expert out' and your question will go back on the board so other experts here can see it.
