Ive offered to pull apart a school-owned Tranquillo to discover its problem.
The symptom is that when I gradually change grind size while operating, from chunks down to the fine espresso range, it works. Turn it off, start to grind again at the identical espresso range and it doesnt push any grinds out its chute. The motor sounds like its running, but nothings coming out, not even flicks of previous grinds.
After pulling it apart to the base burr level, clearing it out, and turning it on, it appears that someone managed to bend the shaft so that the base burr has a wobble. Not noticeable at high speed, but definitely noticeable on the slowdown.
As the nut is fixed so tightly that neither my husband nor I can remove the burr to check the shaft, any ideas as to where we can take it? We live in Newcastle. Is it even worth fixing?
Any tips as to how to get the nut off would be great (weve tried wrench plus steel multi-grip combo).
Is it possible too that the motor has been partially burned out due to the burrs touching? its a 2004 model. Does it have an automatic disengagement of motor from shaft if the going gets too tough?
