whirlpool washing maching thumping noise

10 posts in this topic

I have a whirlpool washing machine. It is model number LSQ9600Lw1. It runs fine until it gets to the spin cycle, it then makes a loud thumping noise till we open the lid or the spin is over. It will then stop or start to fill for the rinse cycle depending on where it is at. It operates fine other than this. It is only about 2 years old. Any suggestions appreciated.

Sounds like one of the washers footings isn't quite on the ground and this allows the washer to rock during spin. More info here.

Thank you for your reply. I ran a spin cycle with no water and the machine is not moving at all, and when i lift the lid and the drum is still spinning the noise although i originally described it as thumping is almost a loud click. It kinda sounds like driving on a flat tire. It clicks or thumps then rests and repeats. Hope this helps, i'm new to this and appreciate the help.

Ah ha!  We've had a rash of this problem here at the Samurai School.  See this thread.

I looked at the drive shaft, it looks good but I took a picture of it.

This may be the "no power to run windiing" issue - is this a thump-click every couple of seconds? Does it happen on all speeds?

Not familiar with that one-- seems like it wouldn't run at all if that were the case.

I am very familiar with the problem of both the high speed and low speed windings being energized simultaneously as a result of a bad timer. But this problem creates a growling noise (called brinneling) in the motor.

Pray tell us more of this "no power to run winding" problem of which you speak, oh thou maddest of the mad!

Here's what happens - Power to start winding, motor starts, centrifugal switch kicks over to run - no power to run winding, so motor slows down again, switch kicks back over to start, the whole process starts again. This is accompanied by dimming of lights if switched on. Motor will overheat and trip out on the thermal. I used to see a lot of this on the Whirlpool-built Kenmore direct drives, the connectors on those are notorious for broken wires/poor connections.

What led me to this was the comment "It kinda sounds like driving on a flat tire. It clicks or thumps then rests and repeats". Usual way to check is by selecting a different speed, need to be helluva unlucky to have it on more than one.

It does it on all speed, but while spinning it doesn't make it it is when i open the top and it stops or it is finishing the spin cycle
