I have a Beko washing machine WM6133W.
Recently, the motor started to change speed every 3 seconds or so. I thought it was a tacho coil that was broken but I found out that it is a ring attached to rotor shaft (where the tacho is reading the speed of rotor). It seems it is made of plastic (brown colour) and it is cracked in half. As it was attached to rotor I'm just wondering if it's possible to buy it as a spare part. Any suggestions?
