Beko Wm6133W Motor Broken
Hello there.. 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?
Photos attached. Thanks. Daniel

Beko WM6133W motor speed fluctuation traced to cracked tacho magnet on motor shaft
- The problem
- On a Beko WM6133W washing machine, the motor speed was changing roughly every 3 seconds. The fault was traced to the ring on the rotor shaft that the tacho reads for motor speed, which was found cracked in half.
- Likely cause
- The strongest evidence indicates a damaged tacho magnet/ring on the motor armature/rotor shaft. The accepted advice and the original poster’s follow-up state that this part is pressed onto the armature and supplied only with the complete motor.
- What fixed it
- The accepted answer advised that the manufacturer typically only supplies the complete motor rather than the individual tacho part, and to check parts availability. The original poster then confirmed the tacho magnet is machine pressed onto the armature, is only supplied with the motor, and would be very difficult to replace separately. A later forum reply described a successful separate repair by removing and refitting the tacho coil/magnet, but this was not the original poster’s confirmed repair.
- Checks to try
- Observed motor speed changing every 3 seconds
- Inspected the tacho sensing ring/magnet on the rotor shaft
- Found the brown plastic ring attached to the rotor shaft cracked in half
- Original poster confirmed the tacho magnet is machine pressed onto the armature and only supplied with the motor
- Parts or tools mentioned
- Complete motor
- Carbon brushes
- Tacho magnet/tacho coil ring
- Screwdriver
- Hammer
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Sadly, and outrageously, many if not most manufacturers only want to sell a complete motor and no parts are available (other than carbon brushes). Try this link and if you can't find a spare part contact them to see if they can find out if one is available or not - Spare parts

Well, finally I found out that the tacho magnet is machine pressed onto the armature and therefore is only supplied with the motor.
Even if it would be available as a spare, honestly it would be very difficult to replace. I've tried to take the whole thing off - without success.
Anyway, thanks much for your advice. I really appreciate that. At least I know what to do.

It's an example of what I've been complaining about for many years. In an era when we are supposed to be seriously concerned about the environment and how many products are scrapped many years before they should be it's an outrage that these companies get away with it. Tacho magnets cost just a few pounds, and the clip that used to hold them in place cost next to nothing. Instead, most machines with this problem will be scrapped because it's too expensive to buy a complete motor.

Hi Everybody,
this thread is a bit old, but it helped me identifying the tacho coil very well. I was succesful with the repair finaly, so, maybe it could help somebody else:
1/ Tacho coil is machine pressed on this Beko motor. However, i was able to remove it
a) I used a screwdriver placing it at the bottom of the coil (under the coil) from the side (facing the shaft), hammering on the screwdriver gentle and shifted the coil by cca 1mm. Be gentle to avoid the damage of the shaft.
b) Then, i shifted the coil by levering using the screwdriver, piece by piece, be patient again
2/ The tacho coil is available in Czech republic for 8euro.
3/ I used some accessories to press the coil on the shaft using hammering. I tried not the hammer on the coil to avoid any damage. I used a screw or the screwdriver extension (see foto) of the same diameter as the inner coil ring, placing it on the inner (gold) coil ring and hammering on that many many times, shifting it piece by piece. It is not easy, but it is possible. I was succesful.
