I have a Sundance Optima spa, I have just refilled it after winter but pump 1 is not sending water to the jets. I can hear the pump running.Pump II is operating normally.

Stuart it sounds like you may have an airlock. Try opening up the massage selector that operates pump 1 while pump 1 is running. Just open up the top nut partially but not all the way. You should hear an air release sound after several seconds if there is an airlock. You may have to pop off the top handle to grip the top nut to turn it counter clockwise.
