Replace the motor or the bearings or all of it or take it to the Service Centre.
The battery is likely to be fine, but what about the electric motor in the saw, in rice as well? The only thing that tends to get damaged is electronic board components.
Rice only works well if it was warmed first, silica gel packs are better. A couple of days should be good, but my advice it open it up straight away and dry with a hairdryer or heat gun.
It is likely that the trigger switch on your saw is faulty and not allowing power to flow to the motor. You may need to have the switch repaired or replaced by a professional. In the meantime, you may not be able to use your saw until the issue is resolved.
The cutterhead is now exposed. If the eight screws in
the cutterhead clamp are not visible, use a piece of
scrap wood to carefully rotate the cutterhead (Fig. S)
until the screws are accessible and the cutterhead lock
lever18engages. This will prevent further rotation of
the cutterhead as you change the knives
Dewalt Jig SawDeWalt Jig Saw MANUAL ManualsOnline comBlade catch wears out too fast
I loved this tool when it was working but after not that much use the teeth that hold the blade under pressure no longer hold hard enough to prevent the blade from coming out. The mechanism that holds the blade has no catch hole, it uses a few serated teeth to pressure hold the blade in place. Unfortunately, once the pressure starts to lessen you can't tighten it down...
I can't even find a part number for this in Dewalt manuals much less the size of such. There are instructions for measuring belt sizes on the web but that's it. No use searching the Dewalt web site for the belt in the product listings. I tried and it defies any seach I can come up with. I gather they must have some internal inventory system that only they have access to. So, that looks like a job for "customer service" 800-433-9258 Monday - Friday, 8:00A.M. - 6:00P.M. Or you can try their email form on their webpage. As I can't even come up with a parts number for the belt I'm a little shy to refer you to some replacement parts dealer whose product quality I would have no way of knowing even if I had the belt size --which I don't. It is not easy to even pull up specifications for the saw you designated and those don't list belt sizes. You would think it was a nuclear secret.
I had this problem when I first purchased my saws-all from Home Depot. There is a screw at the base of the blade housing. Loosen it up a little and the blade lock should pop back into the down position.
