I found my pump not working last Friday. I reset all the electrical and tried to turn on the filter. It makes a groaning sound for about 3 seconds and then nothing. The pump is a Jacuzzi Magnetek 2HP (1.10 SF 2 SPD). I have a 30,000 gallon in ground pool with 500 gallon attached spa. Should I just order a new pump from an online pool store or is there something else I can check? Thank you.
