Elma Super Elite Speed Control Not Working: Rheostat Fix

Hi all,

I have a very specific and perhaps stupid question. I just received a used Elma Super Elite and just did a quick functional check this morning before I start cleaning it, but the speed control does not seem to be working.

Am I correct in assuming that there should be a visually noticeable change in rotation speed even when in air and without a basket attached? Or does it need the liquid to resist the change in torque? The knob itself feels very vague, but as I have no previous experience with this machine that could still be normal.

I have a brand new basket so I can test it, but as the jars are filthy I don’t want to contaminate it nor invests a lot of time cleaning the machine if it is going to have to be returned due to an obvious fault. So hopefully someone here can confirm my suspicions!

Thanks in advance.

Thanks. Yes I can see that the shaft is rotating. I assume there is no easy way to replace the rheostat?

Yes pretty much. I think this one is the last version of the machine so the internals are a little different from what I have seen in other discussions.

There is quite a bit of side to side play in the shaft so I am wondering if it is shipping damage. The seller is promising it was working when they sent it. And from what I can see the wiring is in good condition.

I am guessing this is the part I need, but I doubt there is much hope finding it.

I bought it on eBay so I can return it. It’s just annoying as apart from this it looks like a nice machine and I will loose out on the customs fees.

I decided to return it, which is very disappointing as I had been looking for a good one of these for a long time. Even more annoying is when I repackaged it I realised the box they had sent it in is far too small and the dial is resting on box. So any impact on the box would have been absorbed by the dial.

Although now I think about it, I am not sure that this version has a rheostat? It looks more like a simple switch? I am guessing it is soldered into the main board though so unless I can find an original replacement I don’t know if an off the shelf alternative would work. I don’t have much experience with electronics so am a bit clueless of where to begin!
