COLD Water Heater help needed!

[ViewRVs]

Sorry but I couldn't resist the title!

I have an Atwood GH6-3E cold water heater in my MH that has the heat exchanger and DSI. The unit will not fire up even though the DSI is hard at work sparking away. Actually, the DSI continues on even after the flame came on but that's another repair.

My problem is that after running my LP nearly out (25.2 gallons at Flying J), it will not light up. My fridge and cold water heater wouldn't work on LP when the tank was low but the fridge is back working. The LP regulator does not match my original manual. I have attached a picture. Does anyone know what 1, 2, and 3 are? 3 maybe nothing but it looks like something if that makes any sense at all!

# 1 is your gas regulator
# 2 & 3 looks to be your main gas valve.
Are you sure your DSI is not the problem? If it keeps on sparking then it appears that the circuit is not made. Could be something as simple as a corroded connection. If you're not sure what's what, I'd suggest you take it to a tech.
Best,

I had problem with fridge. Sounds identical to your symptoms.

I lit the flame with a stick lighter and allowed the contacts and parts "burn" off the soot and dirt form the parts. It is working fine now.

If you actually ran the LP lines dry, sometimes it takes longer to purge the air from the lines for one appliance than the others (although I'd think that the water heater was the first in line... but it depends on the layout of the coach...). To aid in purging the lines of air, I generally light each of the stove burners one at a time until they're all going, then shut them off. That generally moves enough LP through the lines to get it close enough to the other appliances that they light pretty quickly. I figured that out with the old manual light fridge in the Safari after waiting FOREVER for the air to purge at the fridge.

I'd agree that it'd be worthwhile to check and clean all of the electric connectors. I'd probably also blow out the "chimney" in the water heater with compressed air just to make sure that you don't have any spider webs or other gunk in it.

If, after all that it still doesn't work, it'd probably be time to trundle off to a repair tech somewhere, 'cause anything else I'd do to it would probably be destructive instead of constructive!
