What to do if the andrews ECOflo EC230/700 Water Heater upper sensor reading is faulty?

If the Andrews Water Heater's upper sensor reading is faulty due to the resistance being out of range, first, check the continuity of the wire harness to the upper sensor. If the wire harness is okay, then replace the upper sensor.
