My 2 year old pump (3rd pool season) has been acting up lately, including generating some real loud vibrating noises which force me to shut the pump down. It looks like it is still moving water around, but the pressure gauge is twitching rapidly, so I am guessing there is a major issue. This has happened 2-3 times before, and usually reseating/flipping the filter around seems to do the trick, but I am not sure what is actually causing it. I uploaded a video showing what's going on:
I am hoping it is not a cartridge issue, since I was told the cartridge for my filter is over $100. Any suggestions/ideas? Thanks!
