Mahlkonig K30 Vario does not turn on
Hello guys! I need your help, if possible. My K30 Vario isn't turning on, I've already checked the plug wires (I didn't identify any irregularities), as well as I changed the socket, even so I wasn't successful. It does not turn on the display, nor does it start the motor through the button located below the dust outlet.
If you can help me find possible solutions, thank you very much.
Best Regards!

Have you tried resetting the button below the power switch on the back?

I don't know if there is any default trigger sequence, but I've triggered it several times. If a standard procedure is required, please, I would like to know.
Thank you for your message.
Thank you for your message.
I had the same issue with my ditting (same model).
It was the power transformator that needed replacing...

I'll bet Sw1ssdude nailed it. After posting and awaiting an update, I looked at the schematic for the K30. The transformer was going to be the next step since the display was dead. However, trouble shooting the xfmr requires some troubleshooting abilities and a DMM.
However, OP posted:
That would possibly indicate something else, as I would expect that a dead xfmr would just burn 'open' and not cause a breaker or 'safety' to trip unless something was shorted.Cristiano wrote:I don't know if there is any default trigger sequence, but I've triggered it several times.

First, I would like to thank you for your message and, at the same time, reveal my lack of knowledge of Electronic/Electrical Engineering ehehehe.Sw1ssdude wrote:I had the same issue with my ditting (same model).

As I live in Brazil, according to the transformer's references, I don't find him here.
What would be the main references I should look for to find a similar transformer in Brazil?
The button located on the back, above the on / off, even when pressed, it remains the same size (I don't know if this is normal), it goes back and forth without locking in any position. The movement is like a spring, always returning to the starting point.BaristaBoy E61 wrote:<font style="vertical-align: inherit;"><font style="vertical-align: inherit;">Isso possivelmente indicaria outra coisa, já que eu esperaria que um xfmr morto queimasse 'aberto' e não fizesse um disjuntor ou 'segurança' desarmar a menos que algo estivesse em curto.</font></font>
Best regards!
The button would click if it was triggered. Like a fuse with a reset function...
Testing the transformer is a bit tricky, but it can be done.
How much voltage does the brazilian electric grid have? 230v or 110v? The frequency does not matter (50 or 60 hz)
You need a transformer with the same size (it is a very common size) and two primary coils and one secondary coil. This would be a direct replacement. In my thread about the ditting k640 i had a single/single coil type, and therefore had to solder in a small jumper cable.
The original transformer is a ERA 030-7713.0

You need this one, or one with the same specifications, and you should be done. I couldnt find an original one, so i made another one work.
How good are you with tools? Can you open up the grinder?
I can guide you through, if you want.

Thank you very much for your contribution.
In my state the voltage is 220v. Unfortunately my skills with electronics is minimal eheheh but I got in touch with a colleague from another state and he will be able to help me.
I searched a lot for the transformer indicated by you, but I didn't find it in my city or on Brazilian websites.
Thank you very much for your attention and availability to help. I decided yesterday that I will send the grinder to this colleague so he can try to solve the problem.
Best regards!
