We continue to have an issue with the electronic monitor for the level in the waste tank. I found the manual in a cupboard yesterday. The troubleshooting section says that it reports the level continuously, but if it can’t get a valid reading it just repeats the last one. It has been repeating the same value for the last week, though it got higher than the value it stuck on last month. I know from our history that with the two of us on board, we need to empty the tank about every three weeks, so despite the reading on the meter, it was time for a pump out.
