Loud grinding noise when machine operating - Zanussi ZWD1470W Front Load Washer / Dryer

Hi
The most common cause of this is the main drum bearing seal has failed and water has washed all the grease out of the drum bearing and knackered it. You will hear a loud roaring noise on the fast spin when this has happened. As it's certainly not a 5-minute-job, it's not economic to have this fault repaired on an older machine if you are paying for the repairs yourself. Get a new machine.
It is fairly unusual for balance weights to come loose as they are usually held tight by locking nuts. I've seen it happen but not very often. Sometimes they break off the drum completely. Symptoms of this are loud knocking noises, the machine attempting to leave the building while on a fast spin and a heavy piece of metal/concrete on the floor under the machine!
