Cool no water out of hot side

I'm a first time motorhome user and just purchased a 2015 Coachmen Leprechaun 220QB. I've pretty much figured everything out, but when I fill the fresh water tank and the water pump is on, water will come out of the cold water side, but nothing, hot or cold comes out the hot side.

Any help would be greatly appreciated. Thanks

Sounds as if the hot water bypass valve is shut.

Sounds like the by pass valve has been open not allowing hot water to run. The hot valve and bypass one are next to the water heater. That’s where mine are. Good luck

Even with the bypass valves turned, you should still get something out of the hot side. Makes me wonder if there's a blockage somewhere. Is this happening at all your faucets?

Make sure you don't turn on the water heater until it is filled with water.

I am not familiar with your rig. Is there a winterization connection? If so check to see if that valve is in-line and out of bypass mode.

Sounds to me like by-pass valve is in normal position. It could be that the water heater inlet valve is in winterized position or the water heater outlet valve is in winterized position or both of those valves are in the winterized position. There could also be a blockage I suppose.

I suggest going on a fact finding mission.

On the outside of the camper, are you getting hit water out of the overflow valve on the WH?
On the other side of the WH, how many valves do you have? What are their positions? A pic would help.
And as others have asked, are you getting hot water at any faucet?

This from the OP

when I fill the fresh water tank and the water pump is on, water will come out of the cold water side, but nothing, hot or cold comes out the hot side.

Have you checked the bypass valves? Do you know where they are?

Start there for now.

Check out this thread for information on the valves.

Can you find your water heater? Your valves are either behind or very near your water heater OR they're plumbed into your water connection panel outside your unit.

As Mr. Dan said, your hot water valves will be behind your water heater. I've attached a pic of the many ways the manufacturers have come up with to plumb the inlet/outlet/bypass valves. Hope it helps you.

All valves are shown in the normal, NOT-winterized, position.

If you are getting no hot water at all, it is most likely the check valve on the discharge of the water heater. Relatively cheap, and easy to change if you can get to the back of the water heater.

Not everyone has a check valve. In fact, I'd say "most" don't.

As Skip12 suggested, trip the pressure safety valve on the outside to see if the tank is full. Do this carefully as water could be painfully hot.

If the WH is empty as in winterized, it will take several minutes before water comes out as the WH needs to fill before it will allow water into the lines.

Open a hot water faucet. with the water pump on there could be a near silent flow of air coming out and that would be normal for the WH tank filling. Mine blows a lot of air before the faucet gets water when the tank has been bled down.

Pull the pressure relief tab on the overflow at the top outside of the water heater. IF you have pressure in the HW tank there will be a blast of water, or air followed by water. Be careful if you have heated the tank it will be HOT WATER

And as always, when you solve this problem, please post and tell us all what was wrong. No matter how obvious or difficult it is, we all learn from these posts. Especially good to learn if we understood the problem and had the answer. Often the contributors miss it and we need to hear what was really going on. Thanks
