I ve had a similar problem where my wie167 machine would not complete a full cycle, sticking on 1 minute, continually spinning and stopping. The problem got worse, with the cycle sticking on 16 - 17 minutes from completion. At first I asumed it would be the pcb ( printed circuit board ) but as these cost the best part of £ 150 for the wie167 it would be more cost effective to buy a new machine. With this in mind I thought I might as well have a go fixing it myself, and succeeded. I removed the access panel on the rear of the machine, and started the machine on a wash cycle. At this point OBSERVE only as the belt drive will be operating. At the bottom of the drum is the motor and on my machine the motor was sparking and sounding not like an electric motor should. I turned the wash cycle off and isolated the machine from the electric and water supply. I tipped the machine onto its back and removed the carbon brush holders from the motor to examine the carbon brushes. and found that the carbon brushes themselves were not worn, but the springs inside the holders that push the brushes onto the commutators were not operating smoothly. Just by blowing any debris out and manually pushing the spring in and out a few times until the action became smooth seems to have solved the problem.The machine now operates correctly. What I now assume to have been the problem is that the electrical fault with the motor/brushes would have been sending corrupted signals back to the pcb.
As a qualified plumber myself, and having a degree in mechanical engineering, I would advise you get a relevent qualified person to assist you.
