What to do if scaling tip vibrates but no spray from Coltene BioSonic S1?

If the scaling tip of your Coltene Media Converter vibrates but there's no spray when you press the foot switch, it could be due to a minimal water control knob setting. Try increasing the water supply using the water control knob. Alternatively, the water system might be blocked, so clean the water line and filter.
