I've cleaned my boards in the dishwasher multiple times without any problems, so it seems they're likely fine—provided nothing broke down when they got wet initially. You can follow a similar approach: use a regular soap packet, run it through the dishwasher, then let it air dry for a few days or use a fan overnight. I've even preheated the oven and placed the items inside, reducing the temperature to around 60-65°C and letting it cool before putting them in. Normally, I wait until the oven has completely cooled before testing. As for the power supply unit, it would make sense to replace it too, as it's essential for the whole system to function.
The main issue with water on computer components is the buildup of sediments after drying. Salt and soot can conduct electricity, risking short circuits. Depending on how much residue is present and how long the damage has been there, you can usually remove most of it using plain water. For tougher deposits, isopropyl alcohol and a brush work well, while ultrasonic cleaners are ideal for surface contaminants. After cleaning, ensure the system is fully dry before turning it on, since water remains conductive. Avoid distilled water—it’s too harsh for most parts—and use regular tap water instead. If rust appears on metal parts like copper traces or steel casings, it could cause future problems. The best solution is replacing the component, but cleaning and applying a protective coating can help preserve what’s left. Hope this helps!
