No hot water to shower

Hi there,

I think what I need is a new cartridge but I thought I would check. If I turn on the shower as normal I only get cold water (for a while the hot would cut in and out but now only cold). I've checked and my combi boiler is no longer kicking in when the shower is running on any temperature setting. However if I turn on the the heating I can have a hot shower. Any thoughts?

May have something to do with the flow rate through the boiler.

 

However I would have the cartridge out and check that the inlet filters are clean (This could cause a problem with the flow rate if they are dirty) if the filters are OK and you are fairly certain that the boiler is OK then the next step is to change the cartridge.
