I had the same problem, after pumping and flushing out the tank I unscrewed the sender assembly from the top of the tank and hosed it off on the dock, not a terrible job.

i will try that how do you flush out the tank? just keep flushing with clean water?? Not sure what you mean.. We get it pumped out everyother weekend but just in case we take a long trip i want to make it work..

After pumping out the tank refill with fresh water and add some Dawn detergent then pump out again.

And hook all the wires back up if you want the lights to light up on the panel.

If you decide to pull out the sending unit, I would take a trailer light plug and splice into both ends, makes it easy to service in the future. Bob

Dang - this is a good idea. Off to the boat this weekend to do this crappy job, with a trailer light plug in hand!

I am off to the boat next week, and will remove both waste unit indicators for a clean as described here....... but am I reading this correctly, that these units are hardwired into the boats wiring loom, as if intended to never be removed or replaced.
