Defy Autowave technology washing machine ERROR issues

I bought a defy washing machine. Autowave technology. Within 6 months it started giving problems. PC board was changed. Another 6 months later same problem. Gives error codes. We fix what they say could be the problem for the error code. Technicians comes out to fix it. But still getting same errors. Worst buy I ever made. When I ask for replacement machine they have long stories. So fed up with DEFY. Tired of reporting problems. I use my previous washing machine for 18 years with not one problem.
