Atwood Model # GC6AA-10E. When I try to start unit on gas it tries to start 3 times and red warning light comes on. When I try electrical the red warning light comes on. Have cleaned the contacts on...
Normally the red light stays on for hydro operation, so within 1/2 hr or so you should have hot water. Red light on gas means problem lighting. A few things to check. Make sure switch at back of water heater is on as well as breaker in panel, for hydro operation.
As far as gas side goes, try going outside and drop cover down, and pull the connectors of and on a couple of times at the spark module, just to make sure you have clean contact, and have someone try switch after, and let me know if it's at least trying to spark. If still not working, there should be a thermal cut-off switch in the brown wire running to center area of water heater to the thermostat, and ECO. ( where square piece of black foam covers them) That thermal cut-off has a clear plastic sleeve over it. Take that out of the circuit. Simply pull it apart at both ends, and then connect wire from spark module directly to THERM/ECO, where it was before.( your just eliminating that piece, and going direct.) See if it lights now, and let me know. Do you have a 12 volt test light, or multimeter? Also, with it turned off, take your finger and push in between spade connectors on the THERM, and ECO, and make sure there isn't a little reset in center that has tripped.
