No HW at taps for 2012 high wall pop-up

I am having an issue with hot water. 2012 HW popup. Water in tank is hot. But, cannot get hot water to any sink or shower. All valves behind heater are open. Opening valve on water heater proves water is hot. Any ideas as to why the hot water is not leaving the heater and going to the faucets?? This is my 2nd trip, and did not have this issue on first trip. Wondering if I am doing something wrong. Thanks in advance.

If you have a bypass kit and that is open, you're introducing cold water into the stream of water. The bypass valve should be "closed" for normal use.

As ependydad and Turbs pointed out, your bypass valve needs to be closed. If you have the valve type as shown in Turbo''s pic, it is closed when the valve handle is turned to the position it intersects (crosses) the pipe itself. It is open when it runs perpendicular with the pipe.

Turbos pic shows the valves at the top outlet (hot/red) and bottom inlet (cold/blue) open (perpendicular to the pipe) but the middle bypass valve (red/blue) closed (intersecting the pipe). This is how yours should be if you have the 3 valve system. Even though all the valves are all pointing the same way, the bypass pipe is running vertically, thus the valve is actually pointed different from the two horizontal pipes. The bypass valve needs to be closed.

Another way that cold water can be mixing with hot water, is if you have the outdoor or indoor shower taps turned on at the faucets, but have the handheld shower wand itself turned off (there is a button on the side of the wand). This is something a lot of people forget about, and turn the water off with the wand, but forget to turn the actual taps themselves off.

I didn't mention, but I'm not getting ANY water from hot side. Open faucet and nothing. On any of the faucets.

Close the bypass valve between the hot and cold.

Frozen line?

Yep, your bypass valve is open. This allows cold water to mix when hot water is demanded from a tap resulting in cold water to the taps.

See this picture identifying it - you need to turn the one circled so that it is "closed".

X3, the bypass valve (the one that connects the half cold/blue pipe and half hot/red pipe) is open. You need to turn the handle so it crosses (intersects) that pipe...just like in the pic Turbo posted.
