Help me debug an osmolator nano

[perverseosmosis]

Howdy. I hope you'll allow me a not-quite-reefing question

I have an osmolator nano which I use to keep the water in my coffee maker topped off.

I've had osmolators die, but this one seems to be dying in a different way. Facts on the ground:

1) When I plug it in, the motor will run for 5 seconds or so (as normal)

2) Rarely (these days), when I plug it in, it will continue and fill as expected until the float trips

3) If I manually move the float, I can always hear the relay tick

4) When the float is low, I only see 2 volts across the pump leads.

5) When it's starting up (and doing it's little 5 second run), I see 10 volts across the pump leads.

I couldn't find in my email when I bought this. So I don't know if its under warranty. Thoughts on what I might replace on the board?

I don't know that anything needs to be replaced, my best guess is that the very thin material of a coffee maker is likely not enough to cancel the fields of the magnet holder so the magnet holder is catching the float which is a magnetic switch and not letting it move easily. I would try a 1/8" shim of acrylic or some similar material between the magnets and the outer wall.

I'd hoped that was the case, however it happens even with the float completely outside the coffee maker and the magnet far away. I can hear the relay (or something) click when I move the float back and forth.

I would then lean toward the issue being the pump, if it draws to much current, it will cause this. Can you send everything in for testing?
