occasional noisy screeching sound

noisy screeching sound from the front of the valve - a plumber suggested that it might need a new washer? Hot and cold both mix well so I don't think it's the cartridge.

This type of noise is usually caused by uneven pressures (cold of the mains and hot from tank or hot from a combi and cold from the tank etc.)

And the other reason is the cartridge is starting to wear internally
