This question is regarding Sirrus Heritage Dual Control - Shower Spares

Heritage Gummer thermostatic

Hot water is getting to the shower valve but the shower will not get very hot. I have taken front off and turned to max

My first thought is a strip down clean lube and fit a service kit.

There is a video at the foot of the service kit page.
