What it is
The Andrews E531 is a pilot injector with a 3.90 size marking, used on Andrews water heaters. It meters the gas supply to the pilot burner, producing the small flame that ignites the main burner. It is listed as a water heater spare for the RFF190 B Series.
Signs this part needs replacing
- Pilot flame is weak, yellow or unstable
- Pilot will not stay lit once the control knob is released
- Soot deposits building up around the pilot assembly
- Pilot flame lifts or blows off the burner
- Difficulty lighting the pilot at all
Before you order
- Confirm the appliance is an RFF190 B Series model
- Check the size marking on the existing injector matches 3.90
- Confirm the injector serves the pilot burner rather than the main burner
