It is common for the small plastic drilling debris to float around and clog screens, They should rinse them out at the factory but in my experience they don't.
Did you try the shower, bath sink and outside shower and did you get water there?
Also hook up the city water hose to the pod and see if it works.
If you got some water out of the hot side at the faucet I assume the HW tank must be full. how did you know it isn't filling?
I had to clean out the screens a few times and I had plastic shards stuck in the check valve and the pump would run every 15 minutes for 5 seconds until I took the pump out and cleaned it.
Good Luck and happy camping!!
