Osmolator 3155 short fill duration and random high level alarm

My 6 year old tunze osmolator seems to finally be aging. It has served me well until now. I noticed a few days ago it's filling duration seems to have reduced to 1-2 seconds instead of the normal 10-15 seconds. Then yesterday the high water alarm went off despite the float switch looking seated and normal. A power cycled seemed to restore it to normal operation for about 24 hours and then the high water alarm went off again. Can this unit be salvaged or is it time to buy another?

Thank you Roger!

I have seen other threads that suspected water entry into the controller. I don't believe that has happened as it has not moved in quite some time.

Roger, is it worth sending it in to you for repair?

Roger any suggestions? I am currently just powering it on a couple times per day and it is working, but I can not leave it on or eventually the high water level alarm turns on, which means the angry wife alarm turns on too. Thank goodness for apex fusion

Water entry will be too high and too low on at the same time.

You are welcome to send it in, but if the pump is several years old that could be a cause, a dying pump can put out a magnetic field, since the float switch is magnetic if the wires are close the float wire will act as an antenna and pick up the field causing a float alarm.

Oh! They are fairly close. Within about 1.5 feet of each other. I will try and separate them and see if that fixes the high water alarm first, and if so I will buy a new pump. Thanks!

That is honestly pretty far, usually we see trouble when the pump cord is zip tied to the float wire. It could be a factor but I was thinking more along the lines of direct contact between the wires at some point.

I found the float wire running right next to my top off container. Since re-routing it the high level alarm has not fired, so it is either a lucky streak or this fixed it. Oddly enough the short pump duration seems back to normal too, which doesn't seem to make sense.

Anyhow I will continue to monitor it and replace the pump if the short duration symptom returns. Thank you for the help!
