mixer valve on gas hot water heater?

When we turn on hot water taps, only cold water comes through. The water in the hot water tank is hot. Any other suggestions, other than the mixer valve. We recently went on vacation for 5 days and set the tank mode to 'on vacation' and then turned it back to regular setting when we returned, but can't figure how this could cause the problem we're having. Any suggestions?

The mixing valve may need to be delimed, the Cash Acme website may have info on how to service that valve.Bob "hot rod" Rohr

Sometimes those type of mixing valves get a bit "sleepy" and need to be woken up. Make a note of where it is now.
Then crank it clockwise full and then counter clockwise. then return to where you had it. Usually that will get it to work properly again.0 -
The mixing valve is certainly a likely culprit. The advise you are getting is correct.
I would be looking for any kind of cross connect. A "Y" hose on a faucet or anything that changed in your plumbing system..."If you can't explain it simply, you don't understand it well enough"

Hello: I might do this little test first: Run hot water from a tap and then go feel all three lines to the mixing valve. What you would like to find is the cold feed to the valve being at room temperature (along with hot water from the tank actually getting to the mixing valve) . If it goes cold, you know the valve is mixing in cold water and that's a problem to fix. Otherwise, it's elsewhere and we can help you pinpoint it
