Our Aqualisa Aquastream shower in our new house is making the most horrendous schreeching/whirring noise it is so bad we can't use it! It is approx 6-7 years old. Can anyone please shed some light on what the problem could be or if you have had the same problem would love to hear from you and what you did. I desperately want to get this fixed as I can't afford to buy a whole new shower and also don't want to rip the bathroom apart putting in a new cheap electric shower!
