Orchestro Plus FNF 543 - nothing works anymore

Mahlzeit,

had a problem since today.

Wanted to switch on the machine as usual, but nothing happened.
Had pulled the plug out and put it back in for a while.
The result is the same.

Haven't been able to find a similar problem.

How to get the four screws on the back out ?
And is there a fuse ?

Many thanks already.

The 4 screws are oval head screws for which there is a special key. With a little skill, you can open them with a pair of pliers.

Now I ordered a new transformer. The primary winding seems to be broken.
Look at this.

So friends.

Trafo has arrived. Used by eBay.

mains filter pulled out, screw loosened from transformer.
old transformer out, "new" in. Fertich.

plug in, machine is running.

appears to be a common error but.
above the transformer the water tank is probably now and then a defective transformer.

I hope I can help one or the other with it.

greeting,

Martin
