How I fixed the water bin of Roomba J7+ Combo

Error message:

Fluid sensor issue. remove and reinstall bit until you hear a click. Next, press Argjay's button for 10 seconds to reboot. (Error 1014)

Solution:

It's still flaky after the solution.

After several tries following instructions from Gemini and ChatGPT, I still could not find the "sensor" of which they speak.

So instead, I did a full wipe down of the internals of the bin, and the internals of where the bin connects inside the unit. 

I used a long wooden q-tip and a stick, mostly dry, which is important. Ultimately, it worked. No more sensor message. The vacuum cleaned, and then it failed again.

It still is flaky, and I have eject and re-secure the water bin in the unit sometimes. Sometimes it even gets confused and tells me it has lost its wifi connection, but it hasn't. 

But I do find the need to have 3 bins on hand. I bought two from ebay because Roomba doesn't offer one, even for a cost. 

When doing lookups, make sure you are specific about the "plus" in Roomba J7+ because the instructions are different, depending on the plus.

My other water bin works for consistently
