If your washing machine is noisy then you need to find out why. Ignoring a noise can eventually prove very costly. Some noises are present during wash, which tend to be less serious on the whole, but the majority happen during spin. We all tend to describe noises differently and it’s not always easy to accurately describe to others, so it can be difficult to work out what’s wrong from a description. 

Washing machine rumbling, and very noisy on spin

One of the most common causes of a noisy washing machine on spin is worn drum bearings. The first thing any engineer would do when troubleshooting a noise is open the door and spin the drum hard by hand. If it makes the noise when spun by hand the main suspect would be drum bearings but to truly check this you need to take off the drive belt and spin the drum by hand because otherwise you are spinning the motor too. If the drum rumbles when spun then the bearings have probably gone. There should be a constant rumble all the time the drum is revolving.

More noise explanations

Coins or other obstructions trapped between the outer tub and inner drum can make horrendous noises as they get tossed about on spin. They usually don't make the noise unless laundry is in though. If you suspect a coin or other object is being thrown around inside on spin this is very serious because as most washing machines now have just plastic tubs the object can punch through it and completely ruin the machine.

Look out for obvious dents and creases in the drum itself as evidence of a coin or similar stuck inside although be aware that it only shows there's been an obstruction in at some point and the coin could have fallen into the sump hose or filter and not actually be the cause of the noise at this time. You may be able to hear a coin or other obstruction if you drain the machine and tip it back and forth or side to side. Objects can slide about and you can detect their presence. It may be possible to manipulate the object to fall into the hole in the bottom of the tub into the sump hose where it can be easily retrieved.
