"pause" isn't something you can reset exactly I'm afraid. Pause means that the washer door was opened mid cycle so all you should need to do is shut the door to restart the cycle. Unfortunately if it doesn't re-start, it means that your door latch assembly has failed and isn't sensing that the door is shut. You'll need to order and replace the door latch assembly to fix the issue.
It's actually a fairly easy part to replace if you're handy. You'll need to unplug the washer and open the door to start with. Then there is a wire ring around the front lip of the rubber door gasket. Use a flat head screwdriver/needle nose pliers and pry the wire ring off. From there you can pull the gasket back out of the way. Remove the screws going into the door latch from the front and reach behind to replace the door latch assembly.
Make SURE the door strike on the door isn't broken too.
that's only a 6$ or so item.
Here's a site for parts and a video on how to replace it.
Hope this helps you.
