Samsung P801 Front Loader shakes violently during spin cycle.

Question 2 also edited for clarity, 'LG' not 'lg'.
No model details again.

Surely not during 'Rinse' cycle? That just adds water and gently tumbles to get the soap out and complete the washing by further agitating the clothes. You must mean during spinning and much depends on if it is a front loader, or a top loader. For both, machine not level front to back and left to right and / or not sitting firmly on all 4 feet.

Top loader, bulky load unevenly loaded.

Front loader, single bulky item causing an uneven load.

Most likely an unbalanced load especially when it improve during the spinning cycle. When it happens stop the cycle immediately and re position the garments evenly in the drum. If this eliminates the shaking it proves that the load was unbalanced if not the springs must be checked for the possibility that one might be unhooked. Check also if all the feet are making contact to the floor by grabbing the loader at the top and trying to rock it in any direction. If there is movement the feet need to be adjusted until thee is no movement possible at all.

Hi

If your washing machine shakes violently or if there's a loud thumping noise during the spin cycle, the load of clothes has probably gotten unbalanced. Open the lid, redistribute the clothes in the washer, then re-start it. Repeat these steps if necessary.

Hi,
When my washer did that, I found that the shocks that hold the tub were bad...

Check out this tip I wrote about that...

I had this problem with my front loader as well. It is probably the mounts or "level shocks" on the bottom of the unit under the tub. I have a Kenmore by Frigidaire and had to replace the "level shocks". I only paid about $43.00 and was not that hard to put on. Look under your machine and see if the shocks are connected to the tub. Check under the top panel also to see if that particular model has mounts up there too.

There are 2 shock absorbers/springs attached to the drum. If one of them breaks it will cause a loud banging noise when you wash heavy loads. This is an easy fix. The part is about $22.00 and it is accessed throught the front bottom panel.

Machine legs should be adjusted so that machine is level and standing on all four legs. The load in the machine should be evenly distributed. Utube has an excellent video on washing machine repair.

You will have harmonic inbalance about 800 rpm on most front load machines, causing them to shake termporarily as it ramps up on the spin cycle. Be sure to check if the shipping bolts have been removed. This is the most common mistake most people make while installing front load machines. If you don't remove the shipping bolts, it will cause most machines to shake violently and can cause damage.

On something like this you will need to remove the washer wrap to inspect the suspension springs & base assembly. Please see the link provided for accessing the inside of the washer. Be sure the shipping pins have been removed. The tub should float freely.

Make sure the washer is leveled properly and all four feet are resting on the floor. If it is level, try running one cysle without any clothes in it to see it is spins without that violent shaking.. you may have also had an out of balance load.. Hope that helps!
