worcester 28i shower pressure/heat problem

[beatstreetz]

hi,
i've recently had a worcester 28i junior fitted(3 months),
now all of a sudden the pressure in the shower has gone and there is no hot water,
there is hot water in the taps and heating,
i've recently bled my rads and re pressurized up to 1.5 bar which seems to be holding,
have i a blockage somewhere???
any help mjuch appreciated,
thanks,
stuart.

If you've got hot water in the taps then it sounds like the shower is at fault. I'd start by checking the thermostatic cartridge in it is OK and that you don't have a blocked inlet filter on the hot side.

Or

If the shower head is blocked and the flow to the shower is poor the flow switch in your boiler may not be registering hot water flow. Sounds like the shower either way. Have you tried taking the shower head off and running it just through the hose?

thanks for the reply,
tried taking the shower head off and given it a good clean,
we have hot water running through it now but still not alot of pressure though,
looked at all the pipes and cannot fathom out what the shower pipe is linked up to,
is it to do with the bar pressure?? which is at 1.5,
