cold water only shower from a combi bolier

[gblivers]

Recently moved to a new property and it has a Worcester 30CDI combi bolier c.5 years old. The combi happily kicks in when taps are being used, however the 2 showers which also run off the mains doesn't or only intermitently. One shower doesn't heat up at all. This is very frustrating only giving cold water. The boiler pressure was very low but we have stablised it to the recommended 1.5-2 bar.

Take the shower head off and try them straight through the hose, it might be just a restriction and the heads need cleaning.

Mick,

Thanks for that, that was of the things whuch was recommended to have a go at and it didn't appear to make any difference. We ran the water for 15 mins and still no change in temperature and no hot water getting through.

What are the make of the showers?
Are they thermostatic or not?

Have a look to see if there is any isolating valves to the shower, close the cold one and see if it makes any difference (i.e. is water coming out and is it hot) It could also be blocked filters or any number of other things
