WLBP 1500 RC

After a burst (private) main we got a lot of sediment into the water system and the shower would only run very weakly and warm . Cleaned out both H and C filters and check valves and thermostatic valve (lots of sediment in the cold filter). Put everything back but now can't get any hot just tepid to cold despite turning the thermostatic valve to max hot. When trying to adjust and correct when you turn it to cold (clockwise) the thermostatic valve clicks at two points? Have I turned it too far - new cartridge needed?

These cartridges do not click at any point , so I would say that you may need a new cartridge.
