Shower off combi running hot and cold

I have a combi Halstead HE 30 in my loft, the past few days the gravity fed power shower runs between hot and cold

The sink hot water taps are ok as far as I can tell, I have mixer taps.

I look at the boiler code as the sink taps run, it stays on H, but when I use the shower, it switches between h and H every 20 seconds.

Any ideas what could be causing this problem? Thankyou.
 
As no another taps have this problem I would suspect the shower as it’s a pumped shower on a combi system

Non return valve failure?
Hi there, All was good until one day the hot water suddenly started running quite a lot cooler. Putting my hand on the output at the boiler it's still hot there so I'm guessing there's a problem with cold water feeding into the hot water somewhere along the line. I have mixer taps on two...
