Dishwasher - Snapping Noise

Snapping sounds while opening the door: 

It is normal to hear a snapping sound when opening the door of models that have a hinged detergent cup lid that you push to close.

 

• The soap cup only opens to a 90 degree angle when in the wash cycle.

• When the door is opened at the end of the cycle you may hear a snap as the cup opens fully.

A snapping sound while running:

 

It is normal to hear a snapping sound while the dishwasher is running.

 

• A dishwasher fills and drains several times during the washing and rinsing cycles.

• Each time it begins to drain, a solenoid energizes, causing a definitive snapping sound.

• This will happen about six times during each run cycle depending on the model and options selected.
