If you have the same as mine, Headhunter.  If it’s been working and now isn’t. First, is it flushing?  Water going down? If no, then place a plunger over opening to seal it and hit the flush button a couple times. Then see if it works proper. If not it could be the adder valve malfunctioning. Also, theirs a timer knob on them (white stem) that adjust the water flow time cycle. Call Newell service and they’ll have a plumbing tech walk you through several steps.
