Most repairs can certainly be done with a do-it-yourselfer and can save hundreds. Of course, you should have the service manual on hand as most of them give disassembly instructions, as well as guidance to faults and how to repair. With this knopwledge, a home-owner can certainly repair their own washing machine. Common repairs go from water pump replacement to draining issues and everywhere in between.
We also sell a diy manual, so if you are a home owner, we highly suggest not only purchasing the service/repair manual, but also the diy manual which goes into even more detail.
So, yes, you can repair your own washing machine!
