Hello - Thank you for choosing GE Appliances for your washer needs. We're glad this dishwasher is cleaning well! However, we're sorry to hear it takes a long time and is very loud. We understand that would be quite bothersome, and we apologize for any inconvenience this has caused.

It is normal for dishwashers to run for up to two hours or more under certain conditions. Cycles times vary because of the clean sensors due to the sensor extending or decreasing cycle time and number of fills based on the soil level. You may learn more about run time here: https://products.geappliances.com/appliance/gea-support-search-content?contentId=38926&_ga.

If you hear the silverware rattling against the door during a wash, tall utensils may be placed in the upper rack to avoid bumping against the inner door during the wash cycle. If you hear the dishes rattling when the spray arm rotates, ensure the dishes are properly. You can see the Loading section of your owner's manual here: https://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-4000218-2.pdf&_ga.

There are many normal sounds you can hear from a dishwasher. Some sounds are normal, while others may be abnormal but have easy solutions. Here are some of the normal and abnormal sounds you may hear and how to correct them: https://products.geappliances.com/appliance/gea-support-search-content?contentId=38923&_ga.
