I recently purchased an Open Box Bosch Dishwasher. Having installed a dishwasher before I was up to the task. Since my new dishwasher did not come with a drain hose I used the old drain hose, but had problems getting it to stop leaking. I then purchased a new universal drain hose and had the same issues. I apparently over tightened the clamp due to the ill fit and ended up crimping the plastic drain hose connector on the dishwasher. After some research I found a brand specific drain hose that works with my dishwasher. It fits much better, but is still leaking because there are a few small gaps due to the crimped plastic. Suggestions on how to fix this? I am really trying to fix this myself instead of pay lots of $$ to have it professionally installed.

Thanks
