Can you tell me, does the noise only happen when you put the appliance into a spin mode?
Ok.. Try loading the appliance with dry clothes and put the appliance on to a spin cycle...
Let me know if the banging is sill there.
Whilst doing this, watch the drum as it is spinning.. Let me know if there are any jumps or speed alterations
Ok, there is a flaf in the kick panel to the right hand lower of the front of the appliance.. Open that and drain off any water using the black tube therein. Once the water is drained off, open the filter and check for coins and other debris..
Let me know what happens and what you find in there.
That's excellent news.Please take the time to rate my assistance using the stars provided (5 stars is best) at the top of the page, as it is the only way I get credited for responding to you.
