Teasmade problem sorted!
Our 1950 D25 Teasmade clock stopped at 8:05 Sunday night -so we had to get out of bed to make coffee Monday morning. The shame of it!
Clearly, this could not possibly go on, so I spent a day sorting it out. A few years ago, I found that the clock motor was becoming noisy - a whirring sound, caused by the Tufnol rotor bearings being worn and attempting to vibrate at mains frequency. Thick oil made a temporary cure, but my better half could not sleep with this, so a quick solution (bodge) was called for, that being two 4K7 resistors in series with the stator coil that gave a weaker field and less 50Hz oomph. Now, the fault was that the resistors had gone slightly high, and the clock would not run unless the rotor was given a spin. So, until I do the job properly and make new bearings, I had a couple of later Teasmades that I was going to make into one; one was an 855 with a missing motor, the other the smaller 854 that used the same motor, but the stator coil was OC. A while ago Mike Barker made a new coil for this one, so the way forward was to make one good Teasmade from two. I stripped and completely cleaned all the parts so the 855 now looks like new and woke us up with a coffee this morning. I’ll post something about the D25 bearing repair when I get time to do it.

"-so we had to get out of bed to make coffee Monday morning. The shame of it!" isn't that what the 'tea now' position is for?

It is now I have a working 855, but the older D25 doesn't have such a thing; all the controls are just two toggle switches.
"Tea now" on Monday was Mike P putting the kettle on in the kitchen!

Re: Teasmade problem sorted!
Thanks for your comments, folks; now I've had the correct caffeine dosage, we'll put the thread in the dishwasher; sooner or later, the D25 fix might be worth a new thread. )
