I have a Hayward Tigershark QC that was purchased in 2016. I think it finally crapped out on me. It will power on for about 5 seconds then shut off. I can push the button under the switch on the power supply and power will come back on but the cleaner cord has to be unplugged and it often takes multiple "pushes" before it comes back on. Power will stay on if i dont plug the vacuum into the power supply. Guessing water intrusion in the cord somewhere is causing the power supply to trip? It moves while it's on for those 5 seconds. I've plugged into regular outlets and not gfi, and same thing happens. Any ideas?
