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
