ECO Testing Points Test ECO’s (electric cut offs): To check all ECO’S simultaneously measure from COMMON TEST POINT to 3 CHAMBER (or 6 CHAMBER) for continuity. If no continuity, then check across each ECO individually. ECO’s may be manually reset after they have cooled. Run cold water and press the stem to reset. Water may need to run for a few minutes. Check continuity to confirm a reset ECO.
