Ideal mini c24 combi boiler fault

[ant80]

Hey Guys,

I need some help.
My boiler as usual works fine, but since a couple of days, behaves in a strange way. I'm a bathroom installer, seen a couple of boiler, but never met this problem before.
So:during the day it starts up, when I need hot water, but when I have a shower it works fine, dont cut out, but after a longer use, it doesn't start up again. If I wait10-15 minutes, its ok again. Ideas?

so anyone?
pls?

Test the thermistor.

It COULD be a thermistor going open circuit when hot but then there are so many other possibilities of why its not working.

A competent engineer may be needed.
