check out the drain pump if drain pump is blocked up water will not get away quick enough and stop machine from spinning
if that is clear
turn bowl by hand and if you get a runble noise then the main bearings are gone
that will need dismantle and replacement or new machine

IF IT ROARS LIKE A JET PLANE TAKING OFF, THE SPIN BEARING IS FAILING. PROBABLY, THE REAR SEAL HAS FAILED ALLOWING WATER TO GET INTO THE BEARING.
THE BEARING HAS LOST ITS LUBRICATION SO IT IS GETTING DRY. IT WILL CONTINUE TO GET LOUDER AND LOUDER THE LONGER REPAIRS ARE PUT OFF.
THE ENTIRE BACK HALF OF THE OUTER TUB WILL HAVE TO BE REPLACED. THE BEARING IS PART OF THAT ASSEMBLY. CAN BE A COSTLY REPAIR.

My eurotech washer has an inner and outer stainless steel drum. The inner drum is supported in the back by cast aluminum supports. (like many other models). The cast aluminum carodes and weakens and breaks. You may find pices of this in the strainer. Not hard to replace and not expensive but very difficult to get the part. Eurotech has been out of the part for months.

It's been designed to fail so that you buy an expensive part.
