This question is regarding Grohe Avensys Flow Control Union Mod - 47767000

Part ?

Our Grohe shower suddenly stopped getting hot, would only get to just above cool. Phoned them, apparently the part I need is the cartridge that fits inside the control unit. Is this the right part?

If it suddenly stopped being hot , then it is because the hot has stopped coming to the shower, there are filters and non return valves in the inlets to the shower or the www.showerdoc.com/grohe-avensys-wax-thermostat-element-00798000 is faulty or the piston that controls water flow is stuck.
All of which would be needed to be checked.

Barrie, we had the shower fitted 10 years ago and it did the same thing after about 4 years. Grohe sent a fitter round who replaced the "cartridge". I phoned them yesterday and they still had the previous replacement info on their system. They said that the part replaced was the one I asked you about and she gave me the part number. I did wonder about the element which is why I thought I'd query it with you.
What does part no 47767000 actually do?
I did ask Grohe if they could organise the replacement for me, as they had done before but they no longer do that. She told me to source the part myself and get it fitted. Hence my questions. Sorry to be a pain.

The part above is like the gear lever in an automatic car.

You set the gear and the internals keep moving to maintain this setting.

The www.showerdoc.com/grohe-avensys-wax-thermostat-element-00798000 and the www.showerdoc.com/grohe-avensys-grohmaster-slider-piston-for-thermostatic-mixing-valves-07587000 move after you have set the temperature that you want to maintain it.
