Buzzing noise from the filter

Welcome to TFP!

Filter noise is usually a result of air in the filter. Does your pump basket fill completely with no bubbles while running?

Bubbles only when I open the basket to clean it out. Unless when I remove the catridge it's not completly closed & air is goin in?

If you had a problem with the filter sealing, you'd have a water leak.
