What do I do if water was spilt on xbox one s.

Hi,

As you know water and electronics and electricity are not a good mix.

The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the console’s operating design and could damage the components.

First do not turn on your console .

Then you need to dis-assemble the console and clean all the affected parts using Isopropyl Alcohol 90%+ (available at electronics parts stores) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA

Here is a link that describes the process.

Electronics Water Damage

As always with electronics, especially surface mounted PCBs be gentle when handling and especially when brushing away the corrosion. You do not want to remove any components from the boards.

Hopefully after you have done all this the console might possibly work correctly again.

Here is a link to the ifixit guide(s) for repairing your console.

If this process seems too daunting, take your console to a reputable, professional electronics repair service, experienced in liquid damage repair and ask for a quote for a repair. If you decide to do this, do it sooner than later.
