5017 ATO Pump

[xabo]

Lately the pump on my 5017 ATO will not shut off completely. After level light comes on, the pump partially shuts down as it continues a slow drip overfilling the sump unless I'm there to lift the pump out of the water breaking the siphon.

Any ideas as to what's going on?

Think I figured it out:

Failure: Water is filled continuously, although this is not necessary at all.

Remedy: The water level of the storage container must not be higher than the end of the feed hose;

Will have to either lower the height of the container or raise the height of the kalkstirrer.

Yes, that is it, it is just siphoning after the pump shuts off.
