Short circuit of a circuit board of the esma 5500

Hello first of all
I have a little problem and that's that my coffee machine flies out the fuse when plugging in the power supply.
Then I measured a little with the multimeter and see there on the circuit board the pins motor + and motor - have passage. I hope you can help me somehow.

If the circuit board is defective or you can still do something there would have someone sell a used one for about 70€.

Laughing stock, used power electronics for 70 Euro. It doesn't even cost that much new. Pull off the two motor connections directly at the motor of the brewing group. Make sure that the cables cannot cause a short circuit and plug in the mains plug. If the FI no longer falls, you have the culprit.

Yes, I had already done that I disconnected the motor
and then connected it to the mains and the fuse was not blown out.

Where can I find the right board for my coffee machine ?

Measure resistance directly at the disconnected motor. Turn the motor one turn, it has 12 ratchets. Write values here.

So thanks a lot for the engine and the circuit board are defective ?

PCB may be defective, but does not have to be. I'm afraid the only way to find out is to measure under tension. And you'd better find someone who's more familiar with measuring.

Thanks a lot for the help I noticed myself that I measured the PCB wrong and had a thinking error but still had a lot of thanks!!!!!

Good morning,

I once had such a problem with the engine. After I had replaced the engine with a new one, the machine ran perfectly. So the circuit board probably has no damage.

Greeting HWS

With me this is not yet the case but have replaced the motor
and then switched on and nothing happened
except that there is general interference wanted to enter the test mode afterwards and there is only Load.
At the third attempt it banged there the PTC2 said goodbye I hope you can still help me a little.
Many thanks in advance !

Additional brew group sluggish?

The brewing unit can be easily turned up and down via the engine.
