Aqualisa shower - Model name?

[Gnans]

Hello everyone,

I'm looking for model of this Aqualisa shower model (pics attached). Based on search I think this is Aqualisa colt concealed shower.

It is leaking continuously in main vent and dripping water from the open close knob as well. The shiwer is fed from Combi boiler. I presume that removes the electric supply question.

I'm comfortable in replacing like for like models. Also anyone know where is the screw or first step to open this?

Thanks in advance,
Gnans

looks like a 600 series to me

It probably needs a new cartridge

Observe the colour ring on the old one
as you have a combi it should be a high-pressure one - there is a chance your existing one is wrong, since it is leaking.

there are dozens of utube videos on that

they are designed so that after removing the round trim, you can maintain them from the front without having to dig them out of the wall. The mechanism is quite simple.

If you're working on it, clean off any limescale using a nylon brush and bathroom cleaner. Plastic parts are safe with acid. Rinse off well. You should be able to make it look and work like new.

It's a very high-quality mixer

And yet this one, in my own bathroom, is absolutely, definitely, certainly a 600.

How do you tell the difference?

because the Colt has thermostatic written underneath the cartridge, but they both use the same cartridge so doesnt matter

I have the other one @JohnD I am in no way any kind of authority on showers

@JohnD By any chance do you where is the first screw or step to remove the outer covering? I suspect it is either behind the Aqualisa label or I should pull out on/off knob.
