Hot water problem

We are out for our shake down trip, in our new 2020 Heartland Mallard, we have hot water everywhere other than the kitchen sink. We have run 4-5 gallons of water through the faucet without any luck. I have tried the faucet in both positions still no hot water. Any ideas will be greatly appreciated.

Thanks

Make sure you water heater bypass is in the correct position. There will be three valves near the HW tank or a three way valve near the tank used when winterizing the unit. If a three valve system check to insure the middle valve is closed connecting the hot water line to the cold water line. If the bypass is OK then it sounds like the kitchen sink may be plumbed wrong?

Check to make sure the outside shower valves are both off. if they are on it will bypass cold water into the hot water line.. But normally it will be cold water everywhere.

You may need to expose the plumbing to the sink to verify it was connected properly, like the hot water line is actually connected to the water heater outlet. I know with our former 3670, it took a bit to get hot water to the kitchen faucet, but not 5 gallons.

1. Is the water flow rate the same in the kitchen whether selecting hot or cold?
2. Is the water flow rate in the kitchen the same as in the bathroom?
