I have an annoying problem with gas water heater - when I switch to ON, after a few seconds the heater clicks on and you can heat the gas burning but after about 5 seconds it shuts off. I reset the switch to OFF then ON again and same thing happens. After 5 or 6 attempts, the heater finally stays on and works normally. Any ideas?
What brand is your HW - If it is a Truma have you must have the outside vent cover off. I think on all brands you must have reasonably high battery voltage - Perhaps try when connected to 240v & the battery charger on to see if it improves the start up.
Thanks Glenn, you are a veteran champ! I found your instructions very easy to follow (you shouldn't under-sell yourself!) and quickly located and removed the fork which was very dirty and rusty. Cleaned it up to look like a new one, reassembled, and it now works like a charm. Thanks again, Bula
