Is anyone else having issues with the Beckett aquasmart low water control,The company I work for brought in the factory rep. to give us a full detail when installing these controls and we are getting call backs for low water lock out,we try to re-set them but we wind up changing the probes.Some of the calls are going on a new 3rd sensor replacement?,Any feedback would be greatly appreciated,We talked to the rep. and he is unaware of any issues with these!!!
