2 TREVI Therm showers - one of them crazy!

Hi there. Very odd, have 2 Trevi Therm traditional showers. One's fine, kicks out hot water all day long. The other has recently gone very strange - when first turned on will flow full pressure for 20-30 seconds, then pressure slowly decreases to a dribble. When moving thermostat past red safety click water comes back on again for a few seconds, but then stops. A more knowledgeable friend diagnosed the problem as being a new thermo cartridge needed, but does this make sense? The on off cart seems fine, from what I can tell. Many thanks for your help

Your friend is right a new cartridge should solve the problem.
