I have the 3lb barrel polisher and for months the barrel keeps falling off the motor and I have to continually
return it to the motor. I think the issue could be that water is leaking from top and bottom lids but I don't know why? I did replace the barrel a few months ago but had the same problem with the new one. I've had the machine for about 6 years and this has only started happening within the past year. Any advice on how to keep the barrel on the motor would be greatly appreciated!
