Osmolator has started overfilling lately

[kozmo02]

I have noticed lately that my osmolator is overfilling, what is odd, is that the water level does not reach the emergency shut off sensor which is about 2 inches above the main sensor, however, the water level rises to a point where it completely covers the main sensor. some times it fills a bit higher than other times, at first I thought it was just a fluke, but I have noticed it happening more and more regularly lately.

I have checked the sensor and have not noticed any buildup that would cause an error, any ideas?

Could it be a siphon? If you have a new full reservoir and the water level in the reservoir is higher than the end of the hose it will siphon until they are even in level. How big is the stank/sump system volume? Any microbubbles?

The osmolator has been running for quite some time and this problem has only recently begun, it is located in a pretty calm area of the sump, no microbubbles that i can see, the osmolator is connected to a kalk reactor and their is a check valve in place between the output of the kalk reactor and the hose to prevent siphoning,

The tank is a 180, there is a 100g refugium, and the sump itself is an Oceanic Model 3, I think it is equivalent to a 40 or 50 gallon tank.

Roger, my osmolator is brand new and is doing this exact same thing. My freshwater resivior is below the tank and I am having a problem with microbubbles. I physically had to lift the float switch which set off the alarm and when I let it go the pump stopped filling the tank.

kozmo, I would watch the function, it could be the check valve has failed. The answer will be what the LED's indicate, if the pump on light is staying on past the fill point then it would be a problem with the controller.

mr9iron, the sensor cannot tell the difference between a bubble stuck on the sensor and being in the air, if you have microbubbles near the sensor it will not work properly and you need to relocate the sensor or create a baffle to solve the microbubble problem. New sensors are particularly prone to microbubbles clinging to them. New plastic is very hydrophobic and a rinse in hot soapy water will help.

ok, I am gone most of the day with school and work but i will keep an eye on it and see if i can catch it in action and i will post what i see. thank you.
