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.
• Models with a "turn-to-close" detergent cup will not have this sound when the door is opened.

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.

Some models do not have drain solenoids, so this sound will not be heard on all models.
