it is a thermostatic one .is it flow switch on combi boiler?hot water seems to be running well everywhere else.of course it is my fualt its broken{wife} please help.
If hot water is available at other outlets, have you considered that it might be a faulty shower cartridge.
What type of shower feed system is it?. If it is gravity fed then you can test boiler perfoprmance also by checking hot water cylinder. I'm not a plumber but a keen DIYer and like you it's always my fault.
