Dreame L40 Ultra CE Detergent Tank Leak

Yesterday I noticed dried liquid on top of the Robo vac in the dock. Today I noticed dripping coming from the compartment where the vacuum bag was so I opened it.

It turns out that the detergent module had been reverse filled with water by the dock and was leaking out inside the compartment out of the dock and dripping onto the Robo vac.

Opening the detergent module shows that it was pressurized to the point of being overfilled and the only source could be the water tank. I had filled this detergent tank roughly 2 weeks ago, and it had been in use regularly up until today.

I don’t ever use the wash cycle. I just changed the filter put a new bag in and put a new roller on and the little brush with 4 sides
