Found Dishwasher Rinse aid pump working, sensor not detecting product, will order new sensor. 10/8/18 Installed sensor and turned unit on, pump ran in prime mode but did not pump any fluid up from bottle. Turned off and on two times and let prime but never pumped chemical from bottle, checked for clog in line, none present. Found pump tube bad (squeeze tube), will obtain and return. Unit operational but requires squeeze tubes. 10/17/18 Removed old squeeze tubes, replaced with New. Turned unit on and both wash and rinse aid primed. Ran through cycle and unit tested okay, unit operational, job complete. Both temps good
