The top ringer roller does lock and unlock properly. However, if the machine is running or after running a few shirts through the wringer, the top pops open. I notice the release bar will slowly move to one side and then it will release. I’ve taken it all apart and the only thing I can think is causing it is that the tab that holds the eccentric in place looks a little worn. Any thoughts? I’ll post a photo of the release bar and try to get a video up in action
