3155 behaving erratic

[Brian01]

Hi,
My osmolator has started behaving randomly after a little more than a year of working fine. Two days ago, I had 2 instances of it turning on but not off until the high water level switch was tripped. This takes about 4-5 gallons of water being added (I have a 150 gallon rubbermaid sump, with an overflow into the return area where the switches are located). Normally when the optical switch is tripped, it turns off after about 25-30 seconds. Reservoir is about 3 feet below the sump. Tried cleaning the optical sensor with both warm soapy water and vinegar, it worked for a day but now it won't turn on at all. The lights on the main unit indicate that the water level is good, even when I have the sensor right out in the air. Tried cleaning again, no help. There are critters growing in the area, I have sponges and tube worms growing on the magnet, but nothing on the sensors that I can see. I saw no bubbles on the sensor, and have looked at it with a magnifying glass, no evidence I can see of crud or deposits remaining, it looks spotless. Tried unplugging and replugging twice in case it just needed a reset, no joy.

Any ideas?

Thanks

Brian

Did you soak it in vinegar for a while? The usual culprit is a haze of minerals, it can be invisible if the sensor is wet but will be a dull haze when dry, usually a 2-3 hour soak in vinegar will remove it.

Hi Roger,
No haze visible, even when dry, but I only went about an hour and a half with the vinegar. I'll try again and give it longer. I'll let you know.
Thanks

If it is clean and nothing is touching it something has to be wrong with the sensor or calibration and if you send it in I will get it repaired.

Problem solved, thanks for the quick turnaround on the repair.
