I have a '17 Compass 23TR. The hot water supply has been a problem since I got it new last year. It sat on the lot a long time. Problem is it takes 10-15 seconds to get up to an acceptable temp, then shuts down after another 30 seconds. The display shows the temperature blinking but no fan or flame going. Turn it off, wait a few seconds, turn back on and the cycle repeats. It seems to be better on city water. Randy at RV service in Yreka CA suggested flushing the system with white vinegar (a gallon of distilled white vinegar costs about $3.50), and to do it 3 times. I basically followed the same procedure for winterizing by accessing the tube on the left side of the rear compartment and attaching a hose and sticking it in a gallon of vinegar. Then took the outside shower head off and put the end in an empty gallon jug. Ran it through, switched jugs, and repeated 2 more times. Then flushed with tank water until vinegar taste/smell gone. Randy said hard water (ours is very hard) can gum up a sensitive switch that has to work for the unit to function. Similar to having to clean the coffee maker. If it is gummy very likely the heater is also gummed up. I also decreased the pressure in a small accumulator tank I had put in the system to below 10psi (the factory setting). So now seems to work much better. I notice Amazon offers a different model Girard 2GHWAM. Anyone know if this is an improved model? Can't find it on their website. Could it be counterfit model?
