Mobile versionStopped draining PMM. Something is humming there, but the impeller does not rotate. I opened everything, looked, there was no blockage. If you force the machine to "believe" in the closed door and use your hands to help the impeller turn several times (it turns very easily), it may begin to drain normally, but this will not last long, until next time.
The technician arrived and said that the pump needed to be replaced. NEFF machine, second generation, 12 years old. He forced me to buy a new butt for 7000 (I don’t know if this is the norm or not, on ozone the Chinese analogues cost 3, but here it’s like the original). OK. I installed it, the drain worked.
I bet you run the program for testing. It washes for 1 hour, drains it, pours it in apparently for rinsing and some nonsense begins. Strange noises. I open it - the rocker arms are standing, barely flowing from them.
That is. something happened to the retz. And somehow it coincided suspiciously.
Now what happened next.
The foreman is confused and suspects the death of the motor. I read the Internet, I see that this can happen with a delaminated impeller.
He removes the ret. Unwinds the snail. Impeller in half. I’m trying to solder it with a soldering iron. He puts it back together, but something goes wrong. Somehow it jammed everything, since the reel armature no longer rotates freely, and when you forcibly turn it, the impeller stands still.
Takes it back apart.
1) Impeller again in half
2) The graphite ring crumbled into pieces into trash
This is the bushing I mean:

He says that he will take it to the workshop and see what he can pick up.
He calls the next day and offers a repair for 8000. But repairing it already cost me 10 and somehow it’s no longer interesting. Especially the fact that why do I need a motor if the problem is in plastic parts. I say that this won’t work, it’s better then I’ll buy a repair kit on ozone and even if it’s Chinese, it costs 1000 rubles, and I can replace it in the future myself. I didn’t go in here, because I didn’t see how and what, now I’ve looked, there are no questions to repeat.
In general, if I don’t have any questions with the impeller repair kit, everything is normal there, then I don’t I’ll understand how to replace this graphite bushing.

The master has merged, he does not have such a sleeve. I asked around on Avito and among those who sharpen bushings made of graphite and nylon - no, no one has one.
The question is simple: what to do?
Judging by the video, this bushing rides in the hole with a large tolerance. Those. Is it possible to order something more or less similar with larger tolerances? Or is the internal diameter up to one hundred mm very important?
