Just be sure someone did not move the top of car switch to make it stop level with the hard stop. I have adjusted over 100 of those type hydros and was a 45hr adjuster with Otis. If the leveling speed is correct and the valve opens to bypass and closes to achieve the speed it is set for and does not leak the mechanical parts of the valve are working properly. The condenser timing on the valve coil and the pump coasting provides the soft stop PROVIDING the filter screens are clean.
