Hi,

I have a Greenstar 30cdi boiler. Currently having a problem with the hot water. The taps in kitchen/bathroom are throwing out boiling water almost to the point where you can't put your hand under it but the shower is only warm almost cold! HW dial set to 4. CH set to 4.

I turned the CH on and set the dial for hot water on the front to max (6), water on the shower gets warmer but not boiling still and the tap water is scolding!

There are no fault codes shown. Pressure is 1.5 bar. Display shows a temp which dropped at first when I turned the heating to about 25 but has gradually climbed back to around 60.

Does the unit need a service? Or would a simple reset solve this? If so, how do I do that?
 
boilers fine then, get a plumber in to your shower fault
 
I'm guessing its a cheap bar shower?

Had no end of faults on these.
