Horrible grinding noise and vibrations during high speed spin
I have a 6 year old Lavamat 46200 (electrolux) and lately it has started making a horrible loud grinding noise and vibrations when it reaches high speed (1200 /min) spin, lasting for about 5 minutes. As soon as the speed decreases, the noise and vibrations disappear and the spin sound becomes normal again.
If i set the spin cycle to 700/min then the problem doesn't happen. I've tried googling it and have found a short 2 min video depicting the exact same problem as mine: https://videa.hu/videok/tudomany-technika/aeg-lav46200-centri-1200-fordulat-centrifugazas-hiba-mosogep-gaDQJsBa4kOo2vd0
Any suggestion on how to fix it is welcome.

Lavamat 46200 grinding and vibration at 1200rpm spin
- The problem
- A 6-year-old Electrolux Lavamat 46200 developed a very loud grinding noise and heavy vibration only during high-speed spin at 1200/min, lasting until the speed drops. At 700/min the machine spins normally.
- Likely cause
- The accepted reply strongly supports worn drum bearings as the most likely cause. Other forum suggestions mentioned a foreign object between the drums or a corroded drum spider, but these were not confirmed.
- What fixed it
- Recommended check was to see whether the inner drum can be lifted up and down on the shaft, which would support a bearing fault. No completed repair was documented in the thread, so the exact fix was not confirmed.
- Checks to try
- Observed that the fault occurs at 1200/min but not at 700/min
- Check whether the inner drum can be lifted up and down on the shaft
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

That sounds pretty bad when it kicks into faster spin. Sounds very gnarly, like a dry and worn out bearing. I wouldn't be surprised if you can lift the drum up and down on the shaft.

One of 3 things, (I believe) is your problem. 1.There could be simply a Bra Wire or other foreign object between the stainless steel inner drum and the outer plastic drum.
2. Again, between the inner and outer drum at the back is the spider arm. A 3 armed metal bracket that holds the drum, shaft and bearings together. This arm is commonly eaten away, dissolved or attacked by the more superior metal albeit the inner drum caused by electrolytic corrosion.
3. The bearings have gone. This is normally causèd by overloading, uneven balanced loads during fast spin which puts immense pressure on the bearings. To test, see by lifting the inner drum if the gap between the inner and outer drum increases and decreases at the bottom behind the door rubber gasket. The inner and outer drum should raise and fall together equally in sync.
1. Is an easy fix
2. Is a complicated costly fix.
3. Newer machines tend to have sealed drums, requiring a whole new drum which can cost approx £200+ and may well need a complete strip down to remove and replace.
Thanks a lot.
I'm going to google everything you just wrote, hoping in can DIY (it's a second hand unit i've bought just 2 months ago for 150 bucks).
At the moment, the unit works just fine using spin at 700/min, so even if i don't manage to sort it out, i'm still going to have a working unit, even though the clothes are a little more water soaked when coming out.
