Welcome to our forum.
A few days ago, the SilentFlo 5000 Circulation Pump on my 2008 Vista started making a loud vibrating noise. It is very noticeable. I turned off the power, took off the outlet hose and there was some lumpy bits of calcium-like deposits, but nothing else. Vibrating noise is still there and when I touch the pump, the vibrations are very strong. Do I need a new pump? Is it under warranty? If I call a dealer who did not sell me the spa, do I still get warranty service? Any advice appreciated.Thanks.
... Do you know why I would be seeing these deposits? ... Also, I have noticed that the Tri-X filters started to degrade after a year. The outside part of the filter where the water enters became very brittle and small holes appeared. I know I need to replace the filters and this probably has something to do with the blocked pump? Any idea on why this would happen?
Turned out to be a dead circulation pump. Bought one from the dealer yesterday and everything works great now. Thanks to you all for your advice.
