I have power to the PSU (toggle switch lights up when turned on), but no power to the actual Tiger Shark cleaner. Happened all of a sudden. Worked yesterday, not today. This is an older unit (PSU P/N 3000 DCZ). Motor unit of the actual Tiger Shark cleaner is P/N 4000 DC. The cleaner has worked perfectly. I took it out of the pool two days ago. Today, when I put it back in the pool the cleaner doesn't seem to have power. The power supply unit has power, so not sure if it's a cable issue or a motor issue within the cleaner itself.
