Dirt bypassing filter
(Salem, OR USA)
We have a Dolphin Nautilus CC plus that has worked great for 4 or so years. Lately it seems the dirt is bypassing the filter somehow. While it picks up some debris and dirt, the water is very dirty after the cleaning (I assume from it being stirred up by the robot) and there is only some debris trapped in the filter cartridges.
Any ideas on what might be wrong?
