new optical sensor?

[Mache62]

Hi Roger,

I have a Tunze auto topoff, the 5017 model. I've been having an issue with the sensor"¦.the other day it failed to shut off until the upper level control tripped and shut it off, then a couple days later I noticed the low level won't light and trigger the top off to fill. Is it possible the sensor is bad? I have soaked it in vinegar and gently wiped it with a cloth but still shows the green light when plugged in even though the water is not up to the sensor. It does do the initial yellow/green 2 sec fill then shuts off and goes to just green even though the water is still low.

Any suggestions or do I just need a new optic sensor?

Thanks, Mary

Yes, it sounds like the optic sensor has failed and we can replace it, just send in the controller with the hardwired sensors and include a note with your return address and phone number.

why not make it easy to change the optical sensor like the light sensor? why hardwire it.

The space is quite small on the board and the optic sensors rarely fail, they should last many years. Even with a plug it would not be a DIY repair in most cases, we generally have to do a calibration as well, older units often did not need this but occasionally we had to replace a capacitor to match the sensor, newer units since Nov 2011 must be calibrated and this requires a special cable for computer connection.
