Called Mayfair because pool filter had stopped. It starts up its own. Repair guy looks and says it is working. Hasn't a clue why it stopped. At our house for 10 mins. We call Mayfair back because pump goes off again. This time it is still off when (the same) service guy comes back. Flicks a couple of switches but doesn't even take out tools to open it up. He says it is broken and needs to be replaced. It will cost $700. The one we have is $1,200 and only a few years old. Kept asking him how he knew it couldn't be fixed - his response - because it isn't working. Really!! Was there 20 mins this time.
