gloworm cxi30

[pensioner76]

My gloworm combi cxi30 started to take a long time before heating water.
yesterday the central heating appeared to be running.
no hot water and low pressure showing on display.
i turned off the electricity and also opened the valve to pressurise the rads.
after a short delay i turned off the pressurising valve and turned the electrics back on.
since then i have had no display, no responce of any kind from the boiler.
there is 237 v on the socket to the pcb (237 between l &n also betwwe l& earth)checked with a digital multimeter no voltage at overtemp stat.
any suggestions

Have you checked the fuse on/next to the pcb?

Try removing the connection to the pressure sensor, think its a pinkish color, if everything comes back on then you need to replace it, sometimes when they fail it looks like a dead pcb when infact it is just the sensor
