SOURCE: how to open the case of a wertheim b20 vacuum cleaner
Take out all the obvious screws around the base and coloured top using the appropiate driver. There is one screw under the flap used to hold the dust filter in place. The flap is spring loaded and can only be removed (as I see it) once the top is taken from the base. To remove the screw I used a pair of long nose pliers and some patience. Once the top is clear of the base, other screws can be easily seen and removed.
My problem was a badly worn bearing at the commutator end of the motor. There was so much movement that the brushes would not follow the commutator with a result of excessive noise and sparking. The brushes had dug into the commutator segments and chipped etc.
The bearing is permanently pressed into the motor end and cannot be replaced. This means a new motor which, in my part of the world, was quoted as $250.00. My neighbour will be purchasing a new vacuum cleaner but after 15 years with the old one he hasn't done too badly!

Hi there,
SmartAlec from NelsonVacuums.com.au here. The ET2000 has a latch that is located at the very end of the machine lid (about 6 cm in front of where hose clips in. If you sit the machine up on its back end you should see the black lever that needs to be pushed in. Now I will also say that it is possible that you have actually been pushing this but the lid still wont open, this is because every now and again the whole latch moves itself out of alignment by about a milimetre. The easy fix for this is a gentle screw drive to assist the relesing of the catch, this needs to be gently pushed in at the same time as squeezing the latch (hand at top of latch screwdriver at base kind of toward the middle of machine). You should be able to get it open like this with only light pressure. Now of course if you need bags or filters please visit us at NelsonVacuums.com.au.
Kind regards Alec
