Banging or Clanking sound as the front loaded washer speeds up
Washing machine - Front loading 6kg - electronically controlled
I am seeking help regarding the a problem described in the next para in my front load washer. The washer is about 6 year old. I am using the word 'drum' for referring to the washing drum which is composed of immovable outside portion and the inside portion both. The inside-rotating-portion of the drum is connected to a spoked sort of a 'wheel' at the back of the drum. A motor attached to the bottom of the drum. The motor is connected using a belt to 'this wheel'. Also like all front loaders it has mounting springs at top (3 in number in this case) and shock absorbers at the bottom (2 in number in this case)).
I want help in resolving a banging or clanking sound (sound is actually somewhat like extremely loud clicks and it seems that two metal pieces or a metal piece against a stone piece are hitting each other). Now, at low speeds (washing or tumbling action speeds) the inner drum rotates without any abnormality. This banging sound comes when the drum is spinning at higher speeds (the draining or spinning action speeds).
This sound started appearing after I tinkered, as explained next, with the 'wheel' and the inner drum mounting over a bearing.
The inner drum as "appears to me" to be ending in a shaft which is mounted inside a single bearing (in its inner hole), while the bearing itself is fixed inside a bracket screwed into the back of the whole drum. I think this is called the tub bearing.
I started tinkering after I had heard grinding noises whenever the drum used to spin - the faster it spinned the louder was the grinding noise. Hearing the noise I thought, may be just simply greasing the 'main bearing' (the one mentioned above - which mounts the inner drum) could solve the grinding noise and also later that assumption turned to be correct.
Upon disassembling the wheel from the inner drum during the greasing attempt, I noticed that the bearing was a sealed bearing type - I thought I should try to replace it instead of greasing and decided to try and remove the bearing. To disengage the bearing from the inner drum, I tried to hammer the inner drum shaft using a 'tiny' hammer that I felt was right to be used considering I did not know the internal mounting at all. The tiny hammer seemed not to do any effect and I gave up and instead tried to push grease past the seals of the bearing. The seal on my side of the bearing seemed not be obscuring the interior completely - even though it was a rubber seal, so some grease went in.
But after using the machine again, the end result was that though the grease seemed to have gone past the seals as the grinding noise had gone a new trouble appeared - the banging or clanking sound at the higher speeds now appeared. In detail what happens now is whenever the drum starts picking up the speed to do the spinning work, there seems to be a loud banging or clanking noise coming out of the drum. Hearing this noise I stop the machine. For inspecting this problem I removed the top cover of the machine and started the operation. I watched the machine's operation while running. I saw that the drum plays freely on the suspension springs when the speeds are slow (I cannot see the underneath shock absorber, since the machine needs to be turned upside down to see the shock absorbers, and I do not yet have any assistant to turn over the whole machine even when the machine is not running). But when the drum is speeded up, the play of the drum first smoothens out, but as the speeds keep rising at one point the loud banging or the clanking sound starts coming and it seems that either the inner drum is clanking inside or the outside drum is clanking against some shock absorber. I do not know if any of the above is possible or if some other thing is causing this high frequency noise - it clanks at about 1 click per second.
Though the one improvement that happened of the girnding noise going away completely - but the starting of more troublesome clanking sound has made the machine useless.
Any suggestions/help will be highly appreciated.
