Why Is My Samsung Dishwasher Making Loud Noise?
Unusual noises from a dishwasher are usually caused by items in the baskets obstructing the spray arms, a blocked pump or worn wash pump bearings.
Common Causes
Spray arm obstruction
The most common cause. If crockery, cutlery or a utensil is obstructing the rotating spray arms, it will cause a repeated banging or knocking noise.
Item fallen to the bottom
A small item that has fallen through the basket can be picked up by the pump or spray arm, causing a rattling or grinding noise.
Blocked or faulty wash pump
A blocked pump impeller will cause a grinding or humming noise. Foreign objects such as glass fragments, labels or food debris can jam the pump.
Worn pump bearings
Worn wash pump bearings produce a persistent grinding or rumbling noise that requires professional attention.
Checks To Try Before Calling An Engineer
Check the spray arms
Open the dishwasher and manually rotate the spray arms. Ensure nothing in the baskets is obstructing them.
Check the bottom of the machine
Look for any items that may have fallen through the basket to the bottom of the machine.
Clean the filter and pump area
Remove the filter and check the pump housing for debris, glass or foreign objects.
Reload the baskets
Ensure all items are loaded correctly and securely so they cannot move or fall during the cycle.
If You Need Spare Parts
If you are confident carrying out the repair yourself, compatible Samsung dishwasher spare parts are available on Amazon with next day delivery.

When To Contact A Professional
If the noise persists after removing obstructions and cleaning the pump area, the wash pump bearings are likely worn and will need to be replaced by a qualified engineer.
