Re: beko wm6167w
If theres a small module attached to the side of appliance its likely the machine has a DC motor, there could be a triac faulty on the main p.c.b which can cause the problem you describe, firstly i’d disconnect power, check cabling from main board to motor & that all cable connections are tight. Check carbon brushes on motor are making good contact also. IF you don’t get it resolved then i’d be trying a main p.c.b, if that doesn’t sort it then DC module & worse case scenarion motor, luckilly for you Beko are really cheap with their parts unlike other manufacturers.
