Besides problems with worn down shock absorbers or springs, stopping to spin is one of the most common issues you might experience with an older washing machine. For some people this might even be the point to consider buying a new machine, since it seems like a quite expensive repair and it might be viewed as not worth it for something 5-10 years old. But in most cases this might be completely unnecessary, since the repair is not that complicated and is also very cheap. But first a word of warning:
Be very careful with what you are doing:
- Always double check that there is no electricity inside the machine anymore: Unplug the power plug and AFTER THAT turn it on a couple of times to get the last electricity used. Besides touching anything it is also always a good idea to use a multimeter to check there really is no electricity left.
- Be are that the metal parts you are about to handle might have sharp edges. You can protect your hands with gloves.
- If you doubt your savety or don't feel confident don't do it or ask a friend who might have done repairs like this already to assist you
For which washing machine does this howto work?
This howto works for all washing mashines that use a Siemens motor. This includes all machines from Siemens, Bosch, Neff and many other brands. Assuming that the motors that need the same replacement part are looking similar and are mounted in the same way, you get a list of all machines this howto works for over at europart.nl. Be aware that the buttons above the list doesn't represent the starting letter of a brand, but the one from a product code you will find at the back of your washing machine.
1. Carbon Brushes a.k.a. "The cheapest parts inside your washing mashine"
Inside the motor that makes your washing mashine's cylinder spin sits a pair of critical parts that make conduct electricity to the spinning part of the motor called carbon brushes. The motor wears them off a bit with every turn and usually after 5-10 years they need to be replaced, if they are not conducting electricity propably anymore. This can happen out of several reasons:
- they are worn off (gone)
- the ends are oxidated
- the springs that push them down are worn off
2. Finding the right replacement part
Most washing machines that utilitize a Siemens motor need carbom brushes with the original part number 154740. You can get a list with replacement parts for your machine on the websites from Europart by searching for your machines's product code, that you find at the back of your machine. The Europart sites are in danish or dutch, but they are the most complete around.
With the original article numbers you can find on these pages, you can also look for cheaper alternatives somewhere else. Be aware that it might not be of the same quality.
3. Step-by-step video by espares.co.uk
Especially how to get the motor out of your washing machine is perfectly covered in the video underneath. How to replace the carbon brushes on the other hand is also being shown, but we found it needed some extra documentation and explanation, whcih we added underneath the video. If you are viewing this page with Google Chrome or Chromium you might need to reload the page to make the video appear (or press F5).
4. Extra information on replacing the carbon brushes
If you already removed the old brushes, just got the new ones and want to put them it, you might wonder how you have to put them in the right way, since they don't have a square end. Just put the motor in front of you like on the pictures underneath and stick them in as shown. You can also see how much the old brush in the right picture was worn of, if you compare it to the new one on the left.
5. Fasten and secure the cables
Before closing your maching up again, you should do one more step to make your repair perfect: fasten and secure the cables. Since the motor is attached to the cylinder, which is rocking all the time, it's not a good idea to leave a couple of cables just hanging around. As shown on the picture, use a cable strep to attach them to the motor. Additionally you might also put some duct tape to protect them agains the sharp edges.
