I started my dishwasher, then a few minutes later I found a couple more dishes so I opened the door to add them to the dishwasher. Something down by the door hinge snapped and broke off, but then the door felt kind of heavy. I shut the door and turned it back on. It didn't do anything, so I pushed the button to restart the cycle. Big mistake. It started filling with water and wouldn't stop and water started running out on the floor. I shut it off. I pushed the cancel and drain button, but nothing happened. Now no lights come on or anything. It is an old dishwasher. What broke and is it worth fixing?
