Smeg wdi12c is vibrating so much on spin cycle it moves about 10cm out and i need to hold it back, any ideas

There are springs and bumpers/shocks in the machine that hold the tub. When they break or come loose, the tub wobbles.

please check if the water outlet pipe is clear by blowing down it to see weather the pipe is clear as the machine wont move on until the water is emptied from the last cycle it needs to empty the wash water first before spin cycle can start, its worth a try eric

If this is a newly installed washing machine have you taken out the four big bolts on the back of the machine? It holds the drum to prevent it from moving during transportation when it was delivered. if machine runs during fast spin it will make the machine vibrate heavily causing it to move

hi
it is the belt problem
check it///thank u
please rate it

Try this for re-setting the balancing mechanism:
With the washer empty, tip tip it forward so that it is just sitting on the front feet. Hold it there for a few seconds, then gently lower the back down. (Often there is a mechanism in the back feet that automatically levels it for you--if this doesn't work, check that the back feet are not damaged.)

Chck to see that all (6) suspension springs are still attached. Check the plastic snubber ring below the mechanism and above the base plate for cracks or contamination.

sure..start by re leveling the unit, with a standard carpenters level.

remove the two wires from pump connect two wires with a test bulb. this would eliminate the control issue if the bulb lights. 240 volt bulb. take it from there

This happened to us before and we had to actually reset the unit. I had to call the tech support and they walked me through the process.
