My Atwood manual and the instructions on the cover door for the heater both say do not replace the electronic module! Lots of people waste money on this without doing the proper troubleshooting.
The worst is trying to light the heater when the tank is empty. Sounds like that was already an issue. I tape off both the switches for electric and propane heating when the tank has been winterized and drained. When it is plugged and the valves are in the correct positions it should be easy to tell the tank is filling. The pump should run for several minutes while it fills the tank. You do so with a HW faucet opened! Leave the pressure relief valve shut! The tank should have air in the top to help with expansion.
Next step is to check the electrical connections. You can pull off the snap connectors and reattach. The next step is to replace the ignitor. While waiting for a new part you can clean the ignitor and check the gap. That sometimes works at least until you can replace the unit.
In your case, the next step would be to find someone who knows what they are doing and how to further troubleshoot the unit. 90% of the time the unit should already be working after replacing the ignitor.
