How old is the skimmer and when is the last time you cleaned the pump? Sounds like a calcium buildup on the magnet of the impeller.

i clean it every 1 month and clean the impeller it a scotch brite and how old im not sure because i bought used.

could the magnet on the impeller started to swell. This would cause the impeller to get stuck. You may need a new impeller from coralvue. Depending on age it could be under warentee but impossible if bought used.
