Techma red light

June 16, 2013, 01:08:42 am

We had this problem 2 yrs ago for a couple of days and now we have it again for the last two trips. The light on the two push buttons for the toilet is red which the manuals says means the black tank is full. All of my level indicators say the black tank is now 1/4 which seems right since I just dumped it a couple of flushes ago.
I turned off all the power to the coach and the light went out. Waited 5 minutes turned the power back in and the light is still red. The toilet works, you just have to push the button and hold it down for about 10 seconds.

Anybody else ever have this problem and how did you fix it?

When you hold the button in you are bypassing the auto 90% cutout so no issue really if the tank is 1/4. I like you have 2 sensors, the one for the Tecma and the Seelevel % . I have seen this problem on another site and I wonder if there is some debris causing the Tecma sensor to read full when it is not?
Maybe a full fresh flush or two might clean out the issue? I can get an Amber light sometimes after empty instead of green if I do not do a good fresh water flush every other one or so.
