Thanks guys, I have done all you have suggested. Still no flow, may be a faulty unit.
It is a Mira Event XS T
Read through the Instruction booklet 3 times and consulted the fault instructions still not working. The bottle in the shower unit is not filling.
Totally confused.
I replaced my old Mira shower with a Mira Event, all fittings were the same, but having turned the water supply on again, there is no water reaching the shower head.
Any ideas
