Electrical – Washing machine won’t turn on – loose connector on PCB – how and where do I reattach it

circuitconnectorselectricalwashing-machine

My washing machine is completely unresponsive when plugged in to a working outlet. I opened up the machine to take a look and found that this connector had come loose. It seemed to me that the 'mouth' of the connector probably attached to the row of 8 pins visible in the top left corner of picture 3 below. I tried pushing it into place but it was still a little loose, so I held it on whilst plugging in the machine to test. No luck, having tried both sides up.

Could anyone a little more familiar with PCBs advise me? Am I attaching the connector all wrong, or is there perhaps something missing?

Any help would be greatly appreciated!

I think you are trying the wrong location entirely.

That appears to be an edge connector [ it clips over the edge of a PCB ], and at first I thought the spot where it goes is on the lower right of the 3rd picture and the lower left of the last picture. But I don't think that is correct, looking closer.

It only goes on one way - the slot cut between the connector pads matches a divider between pins - but the position of the slot [7 pins one side, 1 pin on the other, while the plug has 3 pins on one side, 5 on the other] does not add up, and the closed end of the plug (up in your second picture) requires either another slot or a set of pads at the edge of the board it clips to.

So, you're looking for a different 8-pin edge connector on the PCB, but it'll have a divider between pins 3 and 4.
