Tunze 5017 ATO alarm

[gicol]

I have the tunze 5017 and there are 4 lights flahing and the alram sounding. Heading on vacation and cant figure out why.

I do know the pump ran dry - is it possible I fried the pump?

The pump can run dry. The alarm sounds when the water level gets too high and trips the secondary float switch.

all for lights are still flashing and the alarm is sounding, but the water level it is well below the high water mark. Any idea why that would happen or a fix?

Mine is doing the exact same thing. Just started today.

Try restarting it?

I tried unplugging and letting it sit, I also tried unhooking the pump from the controller. Still getting the alarm.

I think it has to do with the pump. When the controller is on and I disconnect the pump, it seems to function fine (turns pump on without alarm). When I pump the pump back into the connector, I get the same problem as before.

This can be caused by one of the following issues-

1) The controller got wet.

2) Something is starving the controller for power so it is resetting over and over in a continuous loop. Usual culprits are a dead pump, water damage (corrosion) of the pump connection and wiring, or a weak or water damaged power supply, the DC tip that plugs into the controller is one of the most common causes, people unplug it at the controller, it lands in a sump or puddle and the combination of electricity and salt corrodes it instantly, the inside or + of the barrel is what corrodes. As a safety, if the controller ever needs more than 1200mA, it will shut down and then restart.
