Hot water heater not working
We have a 2002 Win Brave (Workhorse chassis). Out hot water worked for first couple of trips, now when we try to use no water comes out of faucet when hot water is on. Pilot is on, we have turned on water pump and water heater switches, but no water out of kit or bath or shower faucets...What are we doing wrong?
Thanks!

2 things to check-
Some bypass kits for winterizing require the correct positioning of 1-3 valves next to the water heater to pull water from the heater.
The outside shower valves must be closed to restricd cold water bypass when the shower is turned off at the shower head instead of the 2 valves. (if getting cold water out the hot side)

Is this your first time out this year? Did you or someone else 'winterize' the water heater and turn off the valves to and/or from it? Good idea to look.

No not the first time this year. Worked in May, but not since. Henry and I are very novice at RVing, but like to problem solve.

Hot water won't run in any faucet unless cold water in bath is on...and it is just room temp that comes out in faucets...

Divert / normal op valve is on normal. Wtr htr bypass / normal is on normal. Drain is closed. Have cleaned strainer. Can feel heat coming from outside vent. Worried that if no water is getting in, the wtr htr will burn up?

Cylinder pump is not on when we turn on hot water. Could it be not working?

Many water heaters have check valves at the outlet and inlet of the tank. They can get clogged up with mineral deposits. These valves are on the back of the tank, hard to get to. You might try removing the pressure relief valve and filling the tank with a couple of gallons of white vinegar. Let sit for an hour or two. Then re-pressurize the system with water pump or hose from hydrant and try to flush.

I did see the intake and output pipes when I wiggled in to look behind WH. I turned the switch behind there on then off. Think I turned off the pilot, so now I need to relight that...is it better to do what you said from front or back?

Not sure about what switch you are talking about. You want tank off and cool before trying to unscrew pressure relief valve. If you can see the hoses at the back of the tank, you might be able to remove them without removing the WH, if there's room.

Willing to bet it is a check valve....Many of us pull out the valve, remove the guts and replace it..Work very well for a quick repair... Water lines should go thru the valve before entering the tank and when leaving the tank..It is probably the one that lets water flow out of the tank but could be either....RKL

Do you have an outside shower that was left on at the faucet and shut off at the spray head?
