Good to know, I didn't realize there was a circuit board behind the idiot lights as we have had no issues with battery or tank level indicators so I haven't had to investigate further. No chemical concoctions used in our case, just a simple flush after dumping black water, tank and sensors are clean and idiot lights reflect tank levels accurately. No issues with fresh, grey, or battery level indicators thus far.
