How do I change the brushes on Hotpoint wmal 621 aquarius

SOURCE: My washing machine has stopped spinning.

it sound like your belt has come off if not wait till its dark put it on spin turn the light off if you can see flashes coming from under the machine it your brushes that need replaced on the motor

SOURCE: WMA54 Hotpoint Aquarius drum does not turn during wash or spin

sound like the contact points on the timer are probebly dirty or arched to where they are not making good contact. you can take and clean them with a piece of emery cloth if you are mechanically inclined and can take the timer apart. Also there's a set of contacts down by the motor ti check too.
Good Luck,

Try unplugging the unit and plug it back in. This may reset the controls.

Hi,
I think that the drum bearings have gone on the machine..
To open the door and spin the empty drum quickly by hand and you should hear the noise or say a less amplifed one.. Also another way to check is to move the inner durm up and down to see if there is any play in it
Check for bearing failure by seeing if there is any vertical movement between the moving stainless drum and the fixed outer drum. There should be no vertical movement between them - if there is the bearings have failed and will soon collapse. Check for rusty spray around where the pulley shaft enters the outer drum - early indication of seal and bearing failure. Another method of checking is to remove the drive belt and rotate the drum by hand - there should be no noise, roughness or resistance to rotation. Changing bearings is an involved job, only attempt if you are mechanically competent.
As for changing the bearings.
Power off, remove covers. Disconnect drive belt, remove drive pulley. Remove heater, thermostat and pressure switch. Check if drum splits at front, rear or the middle. If the drum is a plastic welded one- ie one which doesn't split, then its game over. If it splits at front or middle, drum will prob. need removal from machine. This involves dismantling the suspension and damping system and removal of door seal and concrete weights. Undo the drum fixing system - either a clamping ring or a series of peripheral bolts and split the drum. If the drum splits at the rear, removal from machine probably not required. Remove the clamping system and pull off the rear plate. Seal and bearings will come away with the plate. Seal needs to be dug out with a suitable lever and the old bearings hammered out with a punch from opposing sides of the backplate. Refitting is, as they say, a reversal of the above process.
However Unplug the appliance and take the top off.
Check the weight on the top to see if it's slack.
Open the door and with your palm upward put it on the edge of the drum.
Lift it until the weight comes on. Is there a lot of movement?
Press down on the inner drum and swing it side to side, does it sound/feel rough?
Finally, tip the machine rearward a little and from underneath check to see if the front weight is loose.
If all of the above are ok then it's likely the drum support spider has broken one of it's legs and the inner drum is knocking as it spins.
To sort this out you would need to strip the appliance down and remove the inner drum to try and change the bearings and the inner drum support.
This is a major strip down of the appliance.
Hope this helps

the motor is shorting, it could be faulty brushes if you are lucky. Look at the wires in the plastic connector to make sure they are not sooty from burning. I had to rewire one on my machine.
