Ideal combi pre-heater not working

[Retired Plumber1]

Been out the trade now for sometime now, a little out of touch with the latested boilers.

I have a problem with my Ideal 30 combi boiler as follows.

Heating is fine, no hot water so replaced the turbine now working fine but the pre heater is not working and no fault codes given. Any advice welcomed. Thanks

What model combi is it

Leave it switched off, it’s such an insignificant amount to be kept warm it’s not worth it, just burning gas unnecessarily.
