It depends on the model but AB on most of the AOS the A & B LED's lighting up usually means ignition/flame failure. Ignition/flame failure: The gas control valve/thermostat has reached the maximum number of retries (3) for ignition and is currently locked out for one hour. Cycle the power to the water heater off and on to reset. Basic troubleshooting/solutions: 1 Ensure flame sensor is making good contact with the burner flame and ensure flame is steady. Also ensure supply and manifold gas pressures are within the requirements in the installation manual. 2 Gas supply is turned off - pressure is too low. For low gas pressure, consult with your gas utility. 3 Ensure the flame sensor is clean - use fine steel wool to clean the flame sensor. 4 Check igniter assembly plug and the socket on the bottom of the gas control valve/thermostat for good connection. Replace igniter assembly if the plug is worn or damaged. Replace the gas control valve/thermostat if socket is worn or damaged. 5 Replace igniter assembly. If this does not apply to your model then here is a link to the instruction manuals for all models: Residential Gas

Beware when working with electrical equipment. It may cause electric shock. Check the power supply wires, connections with heating coils. If they are ok then possibly heating coils require replacement.

Domestic Central Heating, Dodge Caravan, well pump or a Pool Heater, or something else. All questions need 'make model (what it is)' as first 3 words.
