mira shower baxi boiler

[grajam247]

Hi All
I have a mira Fino shower(two months old) that is not getting to temp.Had Mira engineer round the other day and he said that there was nothing wrong with the shower ,and that the prolem was that the boiler was not supplying enough hot water.The boiler is a Baxi instant 105e.
I think that the engineer could be wrong because the hot tap in the same bathroom has a ready supply of hot water.
Can anyone give me a clue what to check on my boiler,to try and remedy this problem.
Regards

I could be wrong but I had a similar problem once. Look at the Mira site and download the fitting instructions. You may have too much pressure on your cold supply. My mixer unit was installed for a header tank supply and when a combi was fitted some time later the mixer couldn't cope. I eventually fitted a different Mira mixer as made for a higher pressure.

In addition to this shower problem i have noticed that the rads get warm when the boiler is in its DHW pre heating mode.Does this mean a diaphragm has gone or there is a problem with the diverter.
