Shower Going Hot And Cold.

[Meg]

The temperature in the shower has started to vary. I think it is an Aqua Lisa unit. Any suggestions what the problem could be? Thanks.

Hiya, You could try this link to the Aqua Lisa 'issues' site and see if the solution is simple? http://www.aqualisa.co.uk/frequently-asked-questions/common-faults/
Good Luck!

Meg,
Electric shower?
Combi boiler?
Gravity system (copper cylinder in airing cupboard?)
Thermostatic?
Model number?

Thanks for the replies. I've read Peaspeculiars link but can't identify the problem there.
It's an Aqualisa Quartz shower working off a combi boiler - Worcester 28CDI.

If it's from the Quartz Digital range, then it's a very sophisticated, and expensive unit. In simple "tradespeak", lots to go wrong ;o(

If a conventional thermostatic unit, then most likely the cartridge is faulty.
I don't know if these have a cartridge even. I'd be inclined to bet on an electronics fault.

Not something for your average plumber though. I would contact Aqualisa direct. If they're anything like the other top makes, they'll send someone to check it out.

"Stuff" is getting very specialised these days. You need someone with experience in these units.

Thanks Builder, the firm who installed it are coming to have a look at in on Tuesday.
