Pump question

Yesterday the power went out for a couple hours at my house. After it came on the pump in one of my tanks became very noisy. Nothing I do helps. I was wondering if anybody else has had this issue. Could a power surge have damaged the pump? My 2 tanks with canister filters are fine. This one is a submerged Sicce 1.0.
It's too noisy to live with and I will have to replace it if I can't fix it. The pump is only a couple months old and was working perfectly prior to this.
Thanks for any help.
