Loud screeching noise when the wash and spin cycle ends

That is the brake. Your clutch maybe wearing out. Or the belt maybe slipping because the rollers for the motor maybe wearing out.

Hello friend, thank you for your inquiry!

Based off the information you have provided you are hearing a loud screeching noise during the spin cycle on your Electrolux washer. You will hear a certain amount of motor whine during the spin cycle this is a normal operation of your appliance. -Matt

I have a similar model (WTW4850XQ1) that was making a very loud grinding/screeching noise during the agitation and sometimes the spin cycle. I unplugged and turned it on its front to get underneath and exposed the motor/transmission unit. Took the cover off the belt drive assembly and my drive gear was loose. Simple tightening down of the nut was an easy fix for me. But some times those plastic gears between the drive pulley assembly and transmission crack or the teeth wear down (think it's called the CAM). That is a fairly cheap and easy fix as well ($35). Repair Clinic website has free videos on how to diagnose and fix issues and parts as well. Worth a look.

What is the model number of your unit?

does not sound good. if you can remove a cover on front bottom or on the back you may find a broken shock, or counter weight, either would need replacing before running again

Sounds like a transmission problem. Not worth the repair judging from age.

Good morning! Possibly the noise was due to improper placement of load into the spinner which should be within its capacity load. best regards.

could be the brakes, if the loud noise is like a screech probably your brake rotor and lining need replacing.

flip your washer over and there is a v-belt between the tub and a motor it either needs to tightened or its too tight

is the bottom foam shipping base still on the washer
