My Profilo washing machine used to fill with water first and then start spinning, but now it makes a screeching noise before spinning.

It sounds like your washing machine may have a mechanical issue, possibly with the belt or the motor. The screeching noise could be a result of friction between parts that are not functioning correctly.

To troubleshoot the problem, you can try the following steps:

1. Check the belt: Make sure the belt is not worn, frayed, or loose. If the belt is damaged, it will need to be replaced.
2. Lubricate the motor: The screeching noise may be a result of friction between the motor and its components. Apply a small amount of motor oil to the shaft of the motor to reduce friction and noise.
3. Check for foreign objects: Sometimes, coins, hairpins, or other small objects can get caught in the washing machine and cause it to make noises. Check the drum and other parts of the machine to make sure nothing is obstructing it.

If these steps do not resolve the issue, it may be necessary to call a professional repair service.
