Disassembly
I don't understand how to break it down

Re: Disassembly
Care to explain a little bit more? Don't understand what the issue is.
Re: Disassembly
I don't think this comes apart. Can't it just be pulled off?

Re: Disassembly
I don't understand how to separate.
Well, I decided otherwise. Soldered the reverse ends.
Where can you buy it?
The denomination is not visible. Burned out designation What is this mysterious detail behind the number 023721 3218 766.0164

Probably good enough. Repairing often requires creativity.newhumanoid schreef: ↑09 apr 2023 14:02 I don't understand how to separate.

But what?Where can you buy it?
Without context or schematics difficult to say. Looks like an X or Y capacitor.The denomination is not visible. Burned out designationcond.png
You mean 0163? Or wrong pic? There's nothing behind it? Or you mean "What does the number mean"? It's probably some company internal part number.What is this mysterious detail behind the number 023721 3218 766.0164

Re: Disassembly
This is the pump controller. PROFI ECO VS
There is no scheme.
There was an excess voltage and the capacitor burned out. And I'm afraid that it burned down and this part with the number ... I want to replace these parts. I need to know their denomination and where can I buy them?

Re: Disassembly
Looks like a filter circuit. It was probably an X-cap.

The other part is not a standard part, so you really need to either be able to measure, have the schematic or het the past from the manufacturer

Re: Disassembly
The round blue part is most likely a VDR, a Voltage Dependent Resistor, the diameter gives the power, the voltage is most likely 275 VAC
The wire to board things are most likely 6,35 mm slide contact connectors with some kind of a lock, sometimes you have to slide the housing upwards to disengage the lock, here an example of a TE Connectivity connector.

Re: Disassembly
This looks like a crowbar circuit.
Look at picture below.
The VDR should be high ohm untill the input voltage exceeds the value on the VDR (As Ben said usually 275V in EU).
At that point the VDR will drop low in resistance and shorts the fase and neutral which blows the Fuse, thereby protecting the circuit behind it.
In your case either there was a lightning strike which can cause huge damage also in the circuit behind (lightning struck electronics is 90% game over).
Or there was so much power that the VDR could not handle it.
If I were you I would replace the fuse first, see if the electronics still work (the vdr is only extra safety has no effect on working of the rest of the electronics.
If they still work then also replace the vdr with a bigger power rating as the current one and still at 275V.

Ik ben voor meer techniek op school, maar dan wel vanaf groep 1 basischool.

Re: Disassembly
How can that be?
Then it was not just a normal overvoltage or the fuse / VDR combination was choosen incorrectly by the manufacturer.

Re: Disassembly
I have it so set on my board
Measured the resistance at the input now. 70 ohm
