Ariston A1635 Margherita Control knob spinning

bad timer

Check motor brushes for wear. Brush length is about 30mm new; 10mm or less is too short to do what they're meant to.

Temperature control or speed control for spin

pump blocked - clean out pump/filter/oultet hose. power off

You timer is bad and needs to be replaced. It is located behind the control board

To start ensure that machine is well balanced, and that the load is well distributed inside the drum.

If the problem is not balancing, then the most common is a broken drum bearing spider or a bad drum bearing. A symptom of drum bearing problems is the drum having excessive play when you spin by hand.
Also struts and springs must be checked.

turn the wash temperature dial to zero,
if it starts to wash it could be a faulty thermostat,
if that wont wont work it could need new brushes in the motor

I have an old Margherita washing machine year 2000, my problem I don't have user's manual. Can you please provide me or teach me how to operate the machine?

Thanks & regards

Try Cleaning your filter under the front of the washer it probably has coins and other wonderfull stuff which can cause the clicking issue.
