I installed a new dishwasher this weekend. It was an easy swap out and the electrical, wastewater hose and water supply were all plumbed to the same locations. Lucky me. The water supply feeds into a 90 degree brass (copper?) fitting and goes into the unit. I reused my existing compression ring and threaded fitting to connect to the 90 degree brass fitting. It felt snug when I put it back on the new unit and made sure to not over tighten it (but I still made it pretty snug with a wrench). Sure enough I'm getting few drops of water out of it. Hardly enough to call a leak but I don't want to put the cover back in place with it likes this. I tried to pull the compression ring off just to inspect it before putting it all back together but it wouldn;t come off. Now I'm thinking I need to put a new one on but the old one will be a groan to remove. Any advice? The instructions said to not use teflon tape on the threaded fitting. Should I still try some? Or should I try to tighten the fitting down over the compresing ring even more? I already snugged it up once and not sure if I should crank on it anymore. Of course it is hard to reach and see as well without totally removing the unit.
