Water heater oscillating from hot to cold?
Hoping someone cauld help me with my water heater issue.
I have a 2015 Wildcat Maxx, everything on the unit was working correctly.
This last weekend was my 1st time dry camping in the unit.
So when we went to take a shower after turning on the Suburban model SW6 DE water heater we got hot and cold water oscillating through out the unit.
All faucets do the same thing.
When I came back home I hooked it up to city water and it's the same thing, ( hot and cold ) oscillating.
When I open the relief valve, the water is very hot! So I know the water heater is heating water.
The only Maintence that was done to the unit was by Camping World in Valencia, Ca.
They repaired the water pump that had a stuck diaphram which works perfectly now.
So was hoping someone here could provide some insight into my issue.
Thank You for any replies......

Most likely the bypass valves are incorrect....as the crossover valve either being not fully shut or is open (it should be closed)
This thread may help as to the full operation of your water heater, and if you scroll down to post #3, it has diagrams on the proper position of the bypass valves(s). Note the crossover valve.

I may have misunderstood your post. You said oscillating, so ignore the above from me if you mean by that the pressures are varying instead of the temperatures.
If it's the pressure (not temps)....Are you using a pressure regulator, and/or does your RV have a water filter.

If water heater bypass valves are correct, check the valves in the outside shower. If they are on and shower head is shut off, this can happen.

You may want to look at your O/S Shower also! If the H and C valves are On and the Shower head turned Off,it will allow Hot water to Circulate in the system also!  Youroo!!

Sorry for the confusion, by oscillating, I meant 1st I get cold water, then hot and cold then hot etc.......
But I'm glad to report that the suggestion provided by some of the members in this thread was correct. Apparently when they repaired the water pump they must have opened the crossover valve, so I closed it and all works fine now.
Problem solved !!!!!
Once Again Thank You all for your responses..............
Yours in Camping
