You may be loading your dishes incorrectly or overloading your dishwasher. Make sure all your dishes are tilted properly and that they’re not touching each other or the moving parts of the dishwasher. 

If you don’t load your dishes properly in the dishwasher, water sprayed during the wash cycle might cause dishes to strike against, scratch or even break each other.

If the problem continues, contact an authorized service agent. 

These noises generally occur in the water pipes. The force of incoming water can cause the pipes to rattle as the dishwasher water valve closes. This effect is known as “water hammer” and is a household plumbing issue. Also, check to see whether the hoses at the back of the appliance are banging against it.

If the sound is too loud or if you think damage is being caused to your walls or water pipes, seek the help of a qualified plumber.

It’s normal to hear a clicking noise as your dishwasher goes through a cycle. The clicking sound is either coming from the electronic control panel or from the timer. This is not a malfunction. 

If the sound is rhythmic, the cause may be an item inside the dishwasher tub. If you suspect this to be the case, stop the appliance and drain the water inside to remove the object. 

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.

It’s normal to hear a clunking noise during the wash cycle. The detergent dispenser will make this sound while its lid is opening. This isn’t a malfunction and will occur about halfway through a wash cycle.

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.

It’s normal to hear a humming noise as your appliance is operating. Dishwashers have many parts such as the drain pump that hum audibly. This is not a malfunction.

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.

If the sound is continuous, it might be coming from the spray arms hitting your dishes. Stop your appliance and rearrange the dishes so that the spray arms can rotate freely. Check that no items are restricting the movement of the spray arms before you start your appliance. 

If the sound occurs every cycle, run your dishwasher empty. If the problem persists, contact an authorized service agent.

Some of your dishes may be moving inside your appliance. This isn’t necessarily a problem, but if you think that some items may get damaged, stop your dishwasher and rearrange the dishes. 

If the sound occurs every cycle, run your dishwasher empty. If the problem persists, it might be coming from the motor. In this case, contact an authorized service agent.

Your dishwasher drains and refills several times during a cycle. As it drains, the drain pump makes a snapping sound. This is normal and occurs several times during a cycle.

The sound could also be coming from the detergent dispenser lid if it has a hinged mechanism. When you’re opening the door, you may hear a snap as the lid is set free.

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.

It’s normal to hear a squealing or a rattling pump noise if your dishwasher is new. New dishwashers make this sound because they don’t have any water in them. This isn’t a malfunction and may also occur if you haven’t used your dishwasher for a while.

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.

It’s normal to hear a swishing noise during the wash cycle. It’s the sound of the spray arms releasing water inside the tub. This isn’t a malfunction and will occur several times throughout a wash cycle.

If your appliance isn’t operating normally while making this noise, contact an authorized service agent.
