The blue wire off the water heater circuit board powers the light. you could disconnect connector from water heater and apply 12 volts DC to it. If light comes on, then bad circuit board. No light then check ground at light. check light for continuity.
You could jumper the 12 volt DC at switch to the light wire for a similar test.
This is based on Atwood water heater.
