Question about Braun Tassimo Espresso Machine/Coffee Maker
I'm not sure if this is OT but hope not. Is it possible to repair a Braun Ultra toothbrush? They appear totally sealed but I suspect the base is removable. The one I have appears to charge properly, but only works intermittently or sometimes refuses to work at all. I'd like to clean it inside. Or is this another example of 'throw-away culture'? -- Any help TIA Please reply to Newsgroup Hi, I removed the inner body from the brush and accidentaly broke the coil (I disconnected it from the rest of the brush's inner body). Now I am left with: A bottom cap, a coil, a conical spring, a hard washer and a rubber washer, and the rest upper part of the inner body. I have tried putting the coil in the cap, then the hard washer, then the spring and connecting the coil ending with the spring, so it connects to the bottom of the battery, but this still doesn't allow me to charge the battery (the LED doesn't come on). I have held the end of the coil touching the part where it broke off, while in the charging position, but this doesn't make it charge. Am I doing something wrong? In what order should things be connected? What is the rubber washer for? It is nearly the same size as the hard washer, but thinner... Any help is appreciated. I know I am a fool for openning it in the first place, but I was trying to clean it... Many thanks.... Leo
The Battery is comprised of two 2/3A nicads with spot welded connector tabs. A battery supplier can manufacture this 2.2 volt pack for around $10 US.
To get the battery out first unsolder the two wires from the sides of the circuit board. Then release the three tabs that grip the spring assembly. Next unsolder the bottom -ve battery tab from the bottom end, then unsolder the +ve top tab from the circuit board. You will need a solder ****** to remove all the solder fom the +ve.
You can then push the battery pack out of the tube and put in the new battery pack. To put the bottom of the case back on you have to push it in with the coil wires slightly twisted 1/8 counter cw.
I used a steel ruler in the slots to give good leverage to twist against the force from that spring.

I've just opened up and remounted my Braun toothbrush, an Oral-B model I think.
Your description corresponds.
Order for re-mounting:
Coil, rubber/soft washer, hard washer, spring, ...
The spring has no electrical use: I think it is just used to keep pressure on the washer and improve seal-ness.
The coil has 2 electrical ends, which connect to each (narrow) sides of the small PCB. One of the connections happens to touch the battery holder.
I wanted to replace the battery, but gave up as the battery seems so hard to remove: I don't see how to replace it without destroying everything.
Also, the format is larger than an AA.
