Shower keeps going hot & cold?

[ben100]

My shower keeps going cold then stays like that for a couple of seconds then goes back to hot & this will keep happening the whole time while showering.

It was happening on my previous shower mixer which I then changed to the Mira one I now have & it stopped doing it for a while but now it’s doing it again? I have a combi boiler system.

Have you tried the head and hose for a blockage/kink?

What make and model is your combi boiler?

Yes all seems fine they are both also new & it was doing the same on the old mixer & hose aswell so don’t think it’s that.

It’s a Worcester 35cdi

Have you checked to see if the boiler stays fired and modulates when running the shower?
