Nautilus cc plus

by Joseph
(Carrollton Georgia)

Nautilus cc plus 3 years old, has new foam rings, runs as it should, noticed impeller barely moving, not pushing water out of the top of the unit like previous years. Doesn’t pick up debri like it should. Although it runs a full cycle it does a lot of awkward frontward and back moves periodically. Any suggestions would be great. I’m very handy (mechanically) Thanks
