    I have checked the arms, they rotate freely. I took the unit apart and checked the chopper blade, found nothing wrong. The unit makes the noise all the time, full or empty. I was told that the pump motor had a bad bearing, I bought a new motor and seal and installed it. Worked fine for one load.

Test it when empty and also manually rotate the arms and observe if there is anything stopping it.If there is no noise when empty then check the layout of the dishes,as probably one is sticking higher than others causing the rotating arms to hit it.

Water not pumping from the tank


If the pump is primed, water will come out of the tank when the pump is running. It make take a little time for the tank to fill, but you should hear the pump making some noise. An un-primed pump just makes a motor noise, not very loud.

Loud noise during rinse cycle


Hi


If you hear loud thumping during the spin, the load of clothes may have become unbalanced. Stop the washer and redistribute the clothes, then re-start it. Repeat these steps if necessary. Also check for drum bearing failure if your washing machine is noisy on the spin cycle. Drum bearing failure is common when the bearing seals start allowing water to enter. You can take the belt off and spin the drum by hand, and if the drum rumbles, replace the bearings.

Turn the drum by hand and listen for loud noises. If the drum itself is split or the 'spider' is corroded, broken or has come apart from the back of the drum it will create a loud noise on every turn of the drum. (When the bearings have gone bad, the noise is constant the entire time the drum is spinning.)

Look for obvious dents and creases in the drum or look for coins or small objects stuck inside the tub underneath the drum when a horrendous noise is made while clothes are in the tub.

Clear the water pump from obstructions like coins or small objects when a noise occurs while the washing machine is emptying water.

Remove the sump hose and look for bra wires if you hear a light scraping noise when the drum is turned by hand. You can also check to make sure a wire isn't poking out of one of the holes in the drum. In this case, you can pull the wire out easily with pliers.

Take the belt off and run the motor alone if you hear a high pitched squealing noise to check for motor bearing damage or wear. If you still hear the noise without the belt, it's the motor bearing.

Please get back to us if you have further query else please accept the suggestion.

Where is the noise coming from? If it is coming from your wheels then it would be your wheel bearings. They can get so loud that you cant hear a thing inside your car due to vibration.

Constant loud noise when frig turns on/comes from bottom


when the compressor is running unplug the ref. and if you hear the noise coming from the compressor then
a ballance spring may be broken inside the compressor.

The compressor will run normally with a broken spring it will just be annoying when it shuts down.

There is a loud noise coming from my engine ..sometimes..


oh ok, you probably have air shocks and that is the compressor running... makes sense that it sounds with the engine off... it should not be a loud sound though, normally it's quite quiet and you only hear a faint noise... if it is that loud it's probably a bad compressor
