Had same problem I think its s defect. I had to jump out the stingl to keep pump running because I was getting a 30 second fluctuations of voltage being passed through the line side of the switch. I had constant 110 v going in but 110 v coming out for 30 seconds then 0 v and back and forth until alarm sounded. My relays and wiring were all good so it has to be the stingl. They were in such a rush to produce them for the new law that they were not tested properly and have had many problems. This is my third stingl for the same operation all having different problems. I'd contact the company for a replacement.

Had similar problem with voltage cycling on and off on load side of stingl. I believe its a manufacturer defect. They pushed these things out so fast to meet new law that they didn't have time to test them properly. I'd contact the company for a replacement.

The device isn't "seeing" a good AC input. This could be, most likely, for one of three reasons. The plug isn't good (and not supplying AC, or the plug is wired backwards), also, the cord could be bad (same thing, no AC), or the device, for some reason, is faulty, internally. Try plugging it in to another outlet and see what you get. If you still get the message, the problem is either a bad cord or unit. If the unit's still under warranty, I would have it checked out that way. Otherwise, the unit will have to be serviced, and that can be a bothersome experience, plus costly. If you do choose to have it looked at, make sure you get an estimate first, since repair can often be more than the new replacement cost. Since both parties (electrician and pool man) are tending to think it's the other's mistake, I'm thinking the unit is possibly bad. As an afterthought, most AC control systems use relays to drop the line power. There is a chance that the relay's contacts are corroded or oxidized, and not making good contact, thus not providing the AC input across the relay. If you can get to the relay, often you can take the cover off and clean the contacts with a very fine emory cloth, and electrical contact cleaner. Good luck, and hope this helps

Its either clogged or overheating or internal fault . Do you have to press the red reset button each time.If so there is a fault with the motor and will need to go to electric motor specialist.

if the pump is not a self priming pump, it is possible that the windings may have burned out. use a hose to prime and then try in the Maint, position.

This happens a lot at the pool I guard. If the switch shuts the pump off, when you have it restart the pump, it tries about 3 times to restart the pump and then it displays the error 17 message. I'm not sure what the message means but the switch apparently causes the pump to lose it's prime during restart. You reprime the pump by opening the trap (boxy thing with a see through plastic lid) and sticking a hose in the pipe to the pump until the trap is overflowing. Today someone who didn't know about stingl switches attempted to vacumn the pool without it being in maitenence mode and of course it immediately shut off (so at least the darn thing does it's job). After I pressed the on button it tried to restart 3 times and displayed the error 17 message. So, I reprimed the pump and the pump restarted on the second try. Note that sometimes it will seem to have restarted but the Stingl switch is still in start mode. I'm not sure if it is caused by a timer or because it doesn't like the amount of pressure but the switch often shuts the pump down because it thinks the pump isn't fully running or something. The switch will display "pump on" when everything is normal.

Hope this helps,
