Combi with reduced water pressure

[spanner5511]

In Italy!

A Junkers combi boiler giving strange how water problems.

The flow has reduced to a trickle from the shower and all 3 mixer taps - kitchen, bathroom sink and bidet (we're posh here). However if I leave any tap open on full hot and turn on one of the others mixed halfway the flow from the fully open hot tap increases but with only cold water.

Can anyone make any sense of this?

blocked filter on cold water feed to combi and crossover occurring on mixer taps when opened as no hot flow to counteract it simples

Thanks for your response. I never thought of the cold being blocked as the flow on cold is still pretty good. So I just need to clear or change the filter on the cold water feed? The water is very very hard here, filters on taps constantly full of stones.

Got a guy coming round on Saturday afternoon, so he should be able to fix it pretty quickly if this is the case.

Thanks again
