Where are the brushes located in the washing machine?
Washing machine brushes are an integral part of the engine. Current flows through them, and their interaction with the stator sets the motor in motion. Constant friction inevitably leads to wear, so electric brushes need periodic replacement. Where are the brushes in the washing machine and how to change them?
Preparatory actions
Replacing the brushes is impossible without partially dismantling the washing machine, since they are located inside the electric motor housing. Experienced craftsmen sometimes change brushes without removing the motor, but an ordinary owner is unlikely to be able to do this, it is inconvenient, so it is better to remove the motor. But replacing the brushes itself is very easy and can be done by anyone. What will it take?
Two screwdrivers: thin and Phillips.
Pencil, felt-tip pen or marker.
8 mm wrench with TORX slot (popularly called an asterisk wrench).
Now you need to prepare the washing machine for subsequent dismantling. To do this, do the following:
disconnect the machine from the power supply;
turn off the water supply to the washing machine;
remove the inlet hose, first placing a container under the tube (when disconnected, water remaining after previous washes will flow out of the tube);
On the front panel of the washing machine, at the bottom there is a small square hatch, behind which there is a garbage filter. Take it out;
Thoroughly clean the resulting groove from any debris and dirt accumulated there.
The motor itself is located in the back of the unit, so now the home assistant needs to be moved away from the wall, providing access to the rear panel, and you can start searching for the motor and replacing the brushes.
We replace worn out parts
First you need to dismantle the elements of the washing machine body. Which walls need to be removed depends on the brand of the unit (sometimes it is enough to remove only the back panel, and sometimes the easiest way is to get to the engine through the bottom). Then remove the drive belt by carefully pulling the rubber band and turning the drum pulley.
The wires and contacts of the motor need to be disconnected, but first take a photograph or schematically record their location on paper so that you can reconnect it correctly later. Using a torx wrench, remove the fasteners holding the engine in place, grasp it firmly and begin to rock it to remove it from the housing.
Important! The motor is quite heavy, so rely on your strength or ask someone for help.
Now that the motor is removed, you can start replacing the brushes:
disconnect the brush wires;
move the contacts down;
stretch the springs one by one and remove each brush;
take a new part;
place the tip into the groove;
compress the springs and install them there;
fix the electric brush with the contact by moving it up;
connect the cable.
There are only two brushes and replacing the second one is done in exactly the same way. After repair, return the motor to its place and reassemble the washing machine, performing the same steps in reverse order. When tensioning the drive belt, put the rubber band first on the motor shaft, and then on the “wheel” of the drum.
Reinstalling the brushes may at first be accompanied by uncharacteristic noises when the washing machine is operating or the appearance of an unpleasant burning smell; this is normal and is due to the fact that the graphite rods of the brushes are rubbing against the motor stator. The problem resolves itself after a few work cycles.If you are worried about the quality of the wash or suspect that you might have done something wrong, run a dry wash to check.
