Noise from controller box 6100

[jeffberg]

I woke up this morning and noticed there was a high pitch noise coming from the cotroller box on one of my 6100 pumps. It was too early to mess wit hand I had to get to work. Any ideas, this is the controller box that comes with each pump, not the single or multicontroller. Thanks Jeff.

It means the pump is dirty and needs to be cleaned, follow the cleaning procedure in the manual paying special attention that all parts are present and seperate, parts fused by calcium deposits are the main cause.
