ACE 29.2 No Hot Water after de-Winterize

OK, I'k sure I'm missing something simple. When I winterized, I turned the three valves under the bed to the opposite position so that the red-blue line was open and the blue to and red from the hot water were closed. When I reversed them to start the hot water heater, (red-blue closed and blue to and red from hot water heater open), I don't get any water out of the hot, either on pump or on city water. I must have them wrong somehow because when I turn the red-blue back to open, I fill the hot water tank. What am I missing (and is this documented anywhere in the Thor user manual)???

If I remember correctly I put the vertical lines open or valves straight in line, then the horizontal is off or perpendicular to the line. Hopefully that is right, I'm sure someone will correct me if I'm wrong.

Just checked my notes and that is correct for mine.
For use - horizontal closed vertical open
For winterization - horizontal open vertical closed

I get confused by the colors so that's how I remember what to do.

Yes, that is what I have done. Vertical open and horizontal closed, but it still isn't working. Is there another valve someplace?

This happened to mine and had to take it in. The service guy told me when it got winterized it let particles in the hot water heater guts. Whatever that means, but it was fixed.

It is quite likely that the check valve on the inlet to the tank has stuck solid in the shut position. The fact that you can fill the tank if you have all three valves open is a good indication.

Remove the pipe fitting from the check valve and push the valve open and it will probably work from then on. Not expensive to replace anyway

I think you are correct. I have water up to the cold water inlet valve when I loosen it, but I haven't tried to manually open it. I'll try it in the morning.

Thanks!

So it is definitely the cold water shut feed to the hot water heater. Feeling it with a pick it doesn't open when the knob is turned, while the probe goes right in on the hot water side. I couldn't get it opened no matter what I tried. Looks like it is 1/2 PEX. Local CW is backed up for repairs until June 6 earliest. Lowes sells the PEX tool for ~$60. I've got a query into Thor for the price of the valve. I'm tempted to do it myself, but it is plumbing (meaning always a 3-trip to the hardware store). Anyone out there have experience working with the PEX plumbing in the ACE?
