Hi, I am new here and a quick search on this forum didn’t give any useful results except this one, and it seems it is also pretty new.
I have bought an used Roomba 886 with the Error 2 Problem. The previous user has already tried to replace the extractors cage with original replacement part. However, roomba throws an Error 2 occasionally, stopping its work.
The brushes are obviously clean, I went even further and removed the module completely along with the vacuum bin. It seems this did not disturb the robot at all, it went on with ‘cleaning’ as if everything was running as expected. However, after some minutes it came up with an Error 2 again, although no extractor module was installed.
I have tested both modules (I have the old one with me) on an external power source, they seem to be running smooth with a very little current draw, something below 1A (I can measure again if it is important). And a stall current of 5A if I would hold the brushes. The gears seem to be intakt, since rollers are rotating without any mechanical issues on both modules.
I am not sure if it is a software or a hardware issue, but I am more tending towards a main board failure. Does anyone know what I should check, or is it something that we usually do not mess around? I have some experience and all the necessary equipment at work to be able to replace an SMD component.
Is there something else I should try?
