Milwaukee brushless drill / driver (2801-20) that will not work it fell into water

could be many things, a loose wire, a blown capacitor, anything, but I'm leaning toward worn out brushes.

If you have a tool with carbon brushes open the back and look to the carbon brushes if they are worn replace both armature AND brushes together 3 benefits 1. It runs smooth again 2. more power happy batteries 3. more power longer lasting for the power assembly+switch
If you have a brushless tool there is 1 option open and clean the the switch inside is the only option to do or replace the switch stator unit depends on witch model.

I think this would be a new trade-in machine because of the brushless motor and the marketing technical change of the brand Milwaukee repair is in most cases if it has to do by this brushless tools not interesting anymore to repair or let it repair by milwaukee service only if there is garantee ,but for the end user only there are great new trade-in options and the garantee time should also be transparant and great.
Milwaukee will have repairs in ther own garantee and is not interesting in the between trade when its coming for repairs by others that likes it will ending by competition in service by garantee
as between the big brands mutually.

IF something with water happend first disconnect immediately the battery as soon as possible and make as soon as possible dry inside the battery cells dry with an hairdryer to use as soon as it can be for the batterycells.

the body must also be dried but is in priority on the switch after you have dried the switch spray it with wd40 after drying.

A Drill what has no torque can have bad bearings but i think the drill Brand AND model = X X but it is very often an Li-ion battery tool that is only a 2 or maybe 3 years old but the armatures inside them most of them are coming made by the brand JOHNSON (not Makita) a very nice and very powerfull but also an cheap part and that armatures are far much cheaper then the most people are thinking that the batteries have not enough capacity thats an expensive methode thinking and thats in the most cases wrong sometimes .but 20 on 80 % its the battery sometimes if the tool is too long lasting and working with a bad armature then the batteries will be damaged very soon, if batteries are in short time empty and tool has no power ...
If you think You have an Li ION Battery tool , like Milwaukee or Panasonic AND very IMPORTANT to know is if the tool is making a terrible piercing sound you can take the test you should see you can only buy a new carbon brushholder if the brushes where worn,.... but if you use the tool daily a 3 or 4 weeks long the brushes are having the same length again and its very bad for the most expensive parts of all .. the li-ion batteries that you maybe have bought and much people (the most ) are thinking that the batteries are having a bad capacity but that is not true ,An anchor and replaceable brush holder is much cheaper and are most (new) only selled in a combination together new Panasonic drawings and the tool sounds again real smooth and 2 or 3 years later then you can maybe again use your batteries for in use in a BRUSHLESS powertool. where only a switch internally should be cleaned with solvent or contact spray and with white grease relubricated .
Much people think its a problem with the new brushless tools ,but i find out that i have 3 milwaukee brushless tools cleaned the switch and the batteryconnector and have checked the thickness of the contacts, because if the contacts are bad , its not easy to get separate new parts for this brushless models a separate connector for the batteries is not deliverable by the brushless tools by Milwaukee. only in Australie and also and even worser are the contacts on the Dewalt brushless tools have sometimes in a very early time bad contacts even holes on it on the battery + and - connectors on the brushless powertools. strange but often occurs it has also so much power that its like a welding tool between the contacts in the connectors you not can see, and the tools are to little for the jobs where the most people it for used, (the problem is the heat dissipation because of the power and the extent of the modern tools they are often abused , there where better tools can used with a powercord but they have for the torque look alike less power and are for the modern people to heavy to work with.

The first fuel impacts they made are very sensitive to water . Mine stopped instantly after some water flowed in around the head area.

I have the same problem and its about a year old too.

You can have this rebuilt at any milwaukee service center for about 50 bucks, half the price of a new one.
