Fixing a Bosch 2000 AXT Shredder

Fixing a Bosch 2000 AXT Shredder

I bought a shredder from ebay for £1.75 which had a fault on it of it kept blowing fuses when switched on.  At that price, what did I have to loose.

Got it home, sure enough, popped a new 13A fuse in the plug, turned it on and it came on for about a 10th of a second and blew the fuse.  I decided to take it apart to see if there was any visible sign of blackening or physical damage.  Nothing

Undid the side screws

Undid the lid

Pulled the front containing the switches off

There wasn't much in there, just the back of switches, bridge rectifier and a 450v 20uF capacitor.  There was no damage or blackening to any of the components and figured there was no other components further under the casing except for the power to the motor & if that is gone.... game over.

Even though there didn't appear to be any bulging to the capacitor, I bought a new capacitor from ebay for £9.09 and waited a week for it to be delivered.  Turns out I'd ordered the wrong one as this one had 4 tabs on the top, instead of 2.  Hay ho, bought it now.

Opened the case again and checked the capacitor was discharged by shorting the capacitor to prove to myself, there was no charge in it.  Last thing I wanted was a 340V+ DC shock.

Touching both tabs on the capacitor.  First time I did this was with an insulated glove.  Took it off for the photo

Took the old capacitor out by removing the spade plugs and unscrewing the capacitor, then doing the new one back up again.

There is no +ve or -ve/Gnd marks on the capacitor, so I figure the polarity didn't matter.

With the front still hanging off, I turned the switch on at the front, then plugged it in and turned it on at the switch.  Success!  Started turning and making a very weird noise which went away after a few minutes.

Put the front and top on and spent all afternoon using it.

Cost to buy new (currently) £190.  My spend £10.84 + diesel money for the collection.  Bargain!
