It is unusual that water would cause problems to the electronic equipment (it usually doesn't)!
Look to replace the part of the S7 that you feel had the most damage from the water (if the BB boards are enclosed in the unit, then it was probably the control computer)!
Unless this was a liquid cooler then I'd ask why you had it close to the electronic equipment anyway?
(also, if you have another S7 then test out the BB board and control computer on them to see if they work or not)!

Yep, the bb board was enclosed in the unit, ill follow you advise, and will test the io board and the bb board, i tested the whole system (bb board and the io board), ill do that right away
What do you suggest about the power supply? It doesnt start
It is honestly hard to say as water was introduced to the miner and PSU it sounds like from above store. Even condensation could be bad overtime, really bad and will kill miners.
Just to have water go through your S7 and PSU's it's hard to say what all is wrong. Electricity and water never mix, so adding a S7 in the mix is horrible on the unit. It would not surprise me if it is something you have to send in to see if they can be fixed. And with the water I'm not sure I would be to positive they might be gone.
Only thing for sure we can tell you is from now on NEVER mine where water can be an issue.
Yep i know that, the problem was with a leakage from the neighbors, the water leak was from them, it seems i swaped the bb boards and io boards and the miners started just fine, but i got 3 psu not starting
i thought about a bad fuse, but couldnt see one, thanksPSU's should have a fuse in them. Sounds like you've opened it up already. PSUs look deceptively simple hardware wise but troubleshooting them can be a pain in the behind. I've never fixed a PSU apart from replacing a fuse and those that I've talked to recommend replacing it. The advantage, if you still want to fix it yourself, is that the soldering/unsoldering is much easier than the microelectronics components on the mining boards itself so is completely doable. Hopefully someone else on the forums will have the right expertise.
Correct, this would be my answer that the PSU has had a fuse blown
However, the "blown" fuse, I'd use lightly as it is probably a resettable fuse such as a relay which can easily be switched back on. These will switch back on when energy starts to flow through the entire unit and it is returned back o the PSU and plug socket.
I'd again suggest that this is tested with another miner, if it doesn't work with the other miner, throw it away (unless you know what you are doing) as you could risk your safety trying to fix that or even cause a power serge i the S7s are in a close area (a 1300-2000W spark may shift from the miner to another miner and cause great damage to both if one of the wires in the PSU are exposed - or the spark could hit you or a flamable item in your "farm")!
