Have a fault on my dishwasher, if it's on one trace this should all be soldered together right, not with one pin isolated in the middle? I soldered it and think I've now somehow killed the machine, not got a clue what I'm doing

Correct. All those large silver areas should be connected. Looks like typical screw up. Use jumpers to connect all the large areas and it will work.

post other side of board.

Do not listen to this faggot, all those isolated areas are at a different voltage plane, following his advice will fry the board completely. 

Case in point circled area has an air gap meaning there's very likely a stepdown transformer of some sort on the other side, shorting that will fuck everything

Also what pins exactly did you solder together

That air gap sounds like what I blindly soldered and fucked up. This arrow, going to un-solder it now but I've probably fucked it. The other side is a power relay, also bought a replacement as it was dirt cheap in the hope I've just ruined that not the whole board

Other side

how? undo what you did and post another pic.

Sorry wasn't clear, that was before, now it's joined up to the main patch of silver, going to try unsoldering it again now

>>2602575 (OP)

I think you need to re-state what you did and better illustrate it. your original post is pic related.

Sorry clarity clearly not my strong suit on any of this, read it back and realise it makes very little sense. Either way it's now unsoldered and lives once again. Still not solved the fact it only heats up water for the final rinse but at least it's not completely dead and I've learnt my lesson not to just solder on a (wrong) hunch

Looks like that was intended to collect condensation and fail eventually. Good old planned obsolescence at work again.



My dishwasher was mechanical and it eventually destroyed it’s motor bearings after 18 years.

moron

There's better ways to actually communicate you think he's wrong

Looks pretty clear to me that it should be isolated but I dont blame you for thinking it should have.

One of the contacts for the relay, just happens to end up in the middle of that huge area, but that's all it is, just some unlucky coincidence of how the components are arranged.

If there was a bare trace there, that amount of solder, some would have made a bridge, as it is there is a clear isolation between them, its purposeful.

Maybe connects to nothing and just there for physical strength, or it might connect to something on a different layer.

thanks, this fixed it!
