Ideal Isar HE24 water not hot enough when tap open to maximum

[r05h4n]

My boiler stopped working recently secondary to a PCB fault. I got it replaced but since then my hot water is not hot enough when turned on to the max. It used to burn me! Now its just luke warm.

The heating is fine and the water does get hot when I close the tap to about 1/4 of max.

Any ideas whats wrong with it? I miss hot showers!

Whats the pressure like on the boiler? to be honest with the boiler you have it could be one of a thousand things

It should be on 1 - 1.5 so you have too much pressure for starters, if you have had the PCB replaced then I doubt it will be a problem with that. I know its a silly question but is the hot water stat turned up on the boiler?

Yep its on max.

How do I turn down the pressure - I really want a hot shower!!
