Float level sensor "on" all the time?

[siskiou]

As of this morning, my level sensor is stuck on "on".
The floater itself moves freely, but doesn't shut off electricity when the correct level is reached.

Any ideas?

PS: Hm, now it's working again, after I pulled it and let it thoroughly dry off.
It was submerged for about 10 minutes, when my return pump was off for a water change.
Could some of the electrical parts have been exposed to saltwater during that time?
But it's sealed to prevent that, right?

Fortunately, I have it set to stop topping off after 15 minutes!

Probably time for a new sensor? I wouldn't want to risk dumping a ton of fresh water in my system. Is it an expensive piece to replace? I know I can get new sensors for my JBJ for pretty cheap.

The float is not too expensive. The newer, contactless sensor is out of my budget for now.

i have 3 of them they do the same thing also

 

[siskiou]

You mean, your's act the same way each time they get submerged?

same here, we sell 100's I dont have a single warranty return for a float switch at all here.

Things to check

How old is the sensor
Has the insulating core been damaged by being bent at right angles over the edge of a tank or eroded.

Age should not play a part, the only factor I have ever seen is damage to the lead going into the sensor. If you have been unfortunate to damage your lead then a dab of silicon is a cure all once the sensor has dried out.

I didn't see any damage, but that's exactly what I did at both ends of the black shrink wrap, just in case.

But I'll probably still take it out of the sump during water changes!

Mike I think he's having problem with the float switch type, not the old optical

Yep i know
