Nortec, Primus, SpeedQueen and Ipso share the same technology and the design is very similar between these brands. (Alliance Laundry Systems) Thank you for posting this!
I am manager of a laundry in the uk with Primus washing machines, they are similar to that but a bit bigger. I have the same issue you mentioned about the balance. including before it being so unbalanced it broke apart. have you ever had issues with them?
