Nina S Brooklyn , NY May 24, 2020 Appliance: General Electric Dishwasher ZBD1800GSS Ge Dishwasher Zbd1800gss: One of the tabs that holds the spray arm on had broken off as a result the arm kept falling off. How to replace Detergent Dispenser Assembly (Dishwasher). I replaced the spray arm. It took a few tries before I got it on enough to click into place. So it fell off twice. I removed the top shelf and used one of those rubber jar openers to give myself a better grip. I was concerned that using a wrench might crack the plastic. I slowly applied more pressure until I heard a click. I haven't had a chance to run the machine again but hopefully it's on all the way this time.
