Hi,i have a hotpoint aquarius wf340.which makes a very loud banging noise every time it spins,it works fine otherwise!

more than likely the rear bearing has gone bad and when a load is applied the difference in weight distribution causes the knocking.

If you need further help, I’m available over the phone at https://www.6ya.com/expert/jason_4570d45317834dd3

It could be a broken drum restraint spring, or a worn or broken. or loose shock absorber.
To check the springs, remove the top cover, and you will see the springs.
Another possibility is the concrete weight could be broken or loose.
You need to remove the lower rear panel of washer to check the shockers and concrete weight.
Please rate my solution.
Thankyou.

It is the main drum bearings that is causing the noise.
There is no provision made for lubrication.
It can be done as a DIY fix, but it is a very involved repair, as it means having to remove the whole inner workings of the washer,
Not a task I would recommend unless you know what you are doing, and feel competent to tackle it.
Good luck.

hi take the top of the machine and check the brick at top or bottom of the machine they sometimes come lose .

Most likely the Door interlock is faulty or has fallen apart (through the banging of the door)

Several possibilities for noise. check concrete balance wieghts at top and bottom of washer, make sure they are not loose.
Check drum restraint spring(s) are not broken.
Check suspension legs for wear.
Check for loose motor fixings.
Finally, remove drum belt, and spin drum by hand, tjhere should be noise from bearings, if it feels rough or is rumbling , then main bearings have failed.
Please rate my comments.
Thanks.

Hi, Remove the drive belt from the drum & motor then turn the drum be hand, Is it noisy? if it is then the drum bearings need replacing i have used this website before and they are very good.

Hi,
First remove the filter (if you can do this easily) - place a roasting pan under it to catch the water.

If you cannot get to any filter, remove the rear pipe from the waste pipe, and check it is not obstructed.
If it looks good enough, try a hot wash with 1 cup of soda crystals. This should clear any accumulation of grease in the pipes.

If still no good, you may have to open up the machine to clear any internal filter before the pump, and check pump vanes are still intact.

Pump or outlet hose blocked.

FIRST OF ALL THE PERSON WHO INSTALLED THE MACHINE SHOULD HAVE REMOVED THE TRANSIT BOLTS YOU MAY BE LUCKY THAT ONE OF THE SHOCKS MAY HAVE COME OUT OR A SPRING MIGHT HAVE BROKEN
