Hi All

I have a Bosch 2000 garden shredder which has performed well for a few
years.

Yesterday things started to go awry. It behaved as though there was a
jam, sometimes temporarily.
When a jam occurs the machine makes a stalled vibrating bbrrrr sound.
When working normally it makes a whirring sound along with a light
grating, the grating volume increases with added chomping noise when
material is introduced.

So I removed the plastic covering and cleared some material from the
cutter. The cutter arrangement is a near vertical auger with sharp
flights. By the time I had finished, I could rotate the cutter by hand
in both directions.

I reassembled the machine last thing yesterday.
This morning I fully expected the machine to work. I turned it on and initially it worked in both directions, although before committing to
the run state it made a brief stall noise.

After a couple of run tests without material, it is now making the stall
noise and blowing 13 amp plug fuses.

Before I start taking this apart again, can anyone shed any light please?
Have I just given it too much hammer and caused motor damage or similar?

Thanks for any pointers.

we infer it is a mains motor because 13 A

we infer it is induction because it 'worked in both directions'

And that means it started backwards...

How do I test for this please?

I am not an electrician so would need four-year-old guidance!!!!

Good news is that the capacitor just plugs in, and you don't need a
soldering iron.

Yes. I was dismayed to see how easy it was on the CH boiler fuel pump.
Needn't have got in a Man at all..


PS if you have a reasonably up to date multimeter it will have a
'measure capacitance' range and in my case about a 25% loss in
capacitancce was enough to cause the sorts or effects the OP describes.

Its such a common problem that capacitors are in plentiful supply everywhere

The linked videos are bang on.

The capacitor in my machine had blown the lid and the innards were
making a bid for freedom.
In my defence, I was looking specifically for a mechanical
fault/blockage rather than electric failure.

I've ordered one of these which appears to match the spec of the
existing item.

If you ever need a new shredder get one of the "quiet" ones which have a slow-rotating cutting blade. I used to have one like the Bosch 2000 and
got fed up having to take it apart every time it jammed (which was
annoyingly frequent). I replaced it with a Titan 9w years ago and had no problems. If something gets stuck I just put it in reverse (takes about
5 seconds) and that's that. <https://www.screwfix.com/p/titan-ttshr2800-2800w-200kg-hr-garden-shredder-230v/851gc>

Thanks for the recommendation Jeff.

I was gifted this one from a neighbour, no longer with us. So I want to
keep it running if possible.
Aside from not liking green material, it has performed pretty well.
This is the first tear down and component failure, other issues/jams
have been resolved by changing from forward to reverse.

I had a Bosch "Quiet" shredder for a number of years - the inability to
cope with anything green or wet was always a bit of a limitation. Ok if
you cut down something and then left it to dry out for a week, but not
ideal for feeding in stuff as you trim it. I found as it aged and the
helix lost its sharp edge it got more prone to clogging.

is the first tear down and component failure, other issues/jams have
been resolved by changing from forward to reverse.

I know they have changed the design of these a few times, but the
difficulty I often had with mine was having "cleared" the clog by
running in reverse, it was very difficult to actually pull anything back through the feeder / hopper, so you would often end up just blocking it
again on the same thing that you just reversed out.
