• Dishwasher door making popping noise when opening
• Why does dishwasher door make noise?
• Popping noise when open dishwasher door

Troubleshooting:

Does the unit have a custom panel installed?

• Custom panel could be binding on something causing a pop-like sound.
• Check any signs of rubbing around the door or unit perimeter, which may indicate contact during opening/closing.

Does the door feel like it catches on something when opened?

• Check for obstruction(s), such as plates or utensils that contacted the door when opening.
• Check if the dispenser door is open or closed. Popping could be caused by the dispenser door opening when the unit door opens.

Open and close the door several times. Do you hear a popping sound each time?

• If the noise occurred only the first time, check that the dispenser door did open when the unit door opened.
• To verify, check if dishes are dirty after the wash cycle. If the dishes are still dirty, the soap dispenser unlatched but didn't open. Check for obstructions.

Answer:

If the dishwasher makes a popping noise when the door is opened, it could be caused by a combination of hot air and a tight seal. This is normal.
