I bought a coupler and hose (AP4114683) from appliancepartspros for my Maytag dishwasher a few weeks ago. I installed it and it worked great for about a week. Then it lost it's grip on the faucet and it's water tightness, now water leaks/squirts/sprays from the coupler. It looks like the hard plastic white ring inside the coupler has snapped. Is there something I can do to fix this or will I need to install a whole new coupler and hose? Thanks so much for your help.
