Help, macerator question

On our way to Florida, here in Tennessee with a toliet issue. Macerator (dometic) isn’t working in our 2016 Bounder. The light is green, but the water won’t exit the toilet. The fuses are all good, but the macerator won’t engage, or will only come on for a few seconds. Anyone with a answer or / thought, it would be greatly appreciated. THe black tank is only 1/3 full...... thanks

  • I think your Bounder has the Sea Land vacuum system not a macerator. It doesn't grind just moves the waste with vacuum which means when you use a lot of paper, use a lot of water. When you plunge, just one down stroke works best as up and down may damage the flapper that seals the vacuum in the waste line.
  • Thanks for the help / ideas to everyone, after going through everything electrical and mechanical went to the basics. Borrowed a plunger from the campground owner and in 30 seconds it works again. Obviously looked harder than I needed to and feeling a little embarrassed,thanks again to everyone who responded. Adding a plunger to the checklist.... RTBill
  • That toilet is easily unbolted from the floor and then disconnect the water line. As you look at the back of the toilet, there is a large white assembly with hoses attached. That unit is the actual macerator. Don't attempt to open it up.....don't ask how I know.

    The white assembly is removable. Disconnect the hoses and unplug the electrical. Take the unit outside and flush it via the openings. Once you think it's clear/clean, then you can disassemble the white unit to see if it's jammed.
  • Can you hear anything click near the back? I think mine has a relay there.

    The toilet should unmount easily to get to the back for inspection.
  • Day 2 of first time out since October, no problem day one, just emptied black tank with no issues. Seems mechanical / electrical type problem, never an issue to date.... put glove on, and reached down the exit seems like valve below the toilet isn’t open
