3155 osmolator failure

The pump keeps adding water. The high water alarm keeps being triggered. I have thoroughly cleaned the optical sensor. There are no air bubbles attached to sensor. The unit has been running flawlessly for two years. Any help would be greatly apppreciated.

Did you possibly add a refugium light? Has anything changed with hose routing or reservoir size/position?

Roger,

Nothing has changed. Just Ed worked with it again. Same issue. Overfilling and triggering float switch alarm. Should I send it in for repair.

Problem persists

Roger,

I finally got around to hooking the osmolator 3155 up again after all these month. The problem with it overfilling continues. No bubbles in sump, no refugium lighting. The optical sensor is always slightly submerged in the water. It must be something Iím doing wrong. When you inspected, it worked flawlessly.

Any thoughts would be greatly appreciated.

Is it possible this is just due to the normal timed fills?

3) There is a 3rd possibility but this is relatively obscure and only will apply to tanks under 50 gallons or due to a misunderstanding of how the Osmolator works. The Osmolator has timed functions in addition to sensor controlled functions and for the first 25-30 seconds it is not actually detecting water levels and is instead running a series of self diagnostic tests. The pump will always run for 15-20 seconds when you first power it up, this is so the installer can verify the pump is operational and the pump and tubing are primed and ready to fill. Also, the Osmolator always waits 5 seconds to fill to account for waves and surface movement and overfills for 5 seconds so the pump is cycled on less often. If the tank is under 50 gallons you need to open the controller and reduce the pump speed to ďnanoĒ and if it is under 30, an additional restriction such as a drip irrigation valve might be needed, this will reduce the amount of water added by these timed sequences to avoid raising the float.
