IDEAL LOGIC COMBI 30, hot water not very hot

[Retired Plumber1]

IDEAL LOGIC COMBI 30, hot water not very hot, water flow fine. Would I be right in that the diverter valve cartridge needs replacing. Any other suggestions

What’s the flow rate and temp rise?

Can we have some more information please is this a recent occurrence how old is the boiler is there a filter fitted a picture of the boiler would help ?( Your boiler will only raise the cold incoming temperature by 35 degrees the recent cold snap could quite easily have lowered it to 2-3 degrees does the water get hotter if you slow the tap flow down ? Does the boiler go on then off repeatedly when the hot tap is turned on ? Regards kop

Thanks for the reply,
Additional details as follows
Boiler age about 8 yrs, flow is good, the problem has been with us for about 2 months, boiler stays on continuously not cycling, water temperature is 38c
I have reduced the flow rate but no difference
Regards

Is this all taps / outlets or just a couple?

Try turning the heating off , run just the hot taps and feel the heating pipes and see if any heat is going down them .
Otherwise its the case off and somebody gas safe required

Try turning the hot water temperature dial down and up again to max to see if that makes a difference.

No hot water at all? I seem it not recognising the tap opening, or does it fire up but no hot water?
