Ultima Switch Trouble

[labestia]

I recently installed a Johnson Pumps Sump Pump to collect the condensation from our A/C.

All worked good yet recently when the switch is activated by water and the pump runs dry the switch does not turn automatically off. If I take out the fuse and re-install it the switch will reset and will stay off 'till water activates it again and the same problem comes up.

Help Please!!!

PS: The switch is not installed lower than the pump...

Ugh! This is really bad news! I had the exact same problem with the Witch Switch (same concept,though the switch is a little more complicated). I recently replaced it with the Ultima. I was really sold on Johnson, and so far, It's worked fine. However, the similarity in issues is rather scary.
Worse yet, I was going to buy another Which Switch and give it a second try, as it fit a particular purpose for another of my pumps, better than the Ultima. The Chandlery I go through said they no longer carry the Witch Switch because it has issues and Witch Switch won't warranty the product for more than a year. I like the idea of the electronic switch, but am wondering if it's not up to the marine environment. Please contact Johnson customer support and let us know what they tell you.
