No, it is not necessary to put soap into a new dishwasher before running it for the first time. New dishwashers typically come with a thin coating of protective oil or grease, which is applied during the manufacturing process to prevent rust and damage while the appliance is in transit and storage.
Before using the dishwasher for the first time, it's essential to run an empty cycle to remove any residue, dust, or manufacturing oils that may still be present. This process is known as "priming" or "cycling" the dishwasher. It helps ensure that your dishes will be cleaned effectively without any unwanted substances or odors.
Here's how to prime your new dishwasher:
Remove any packaging materials and stickers from the dishwasher interior and racks.
Check the dishwasher manual for specific instructions related to priming or running the first cycle.
Place a dishwasher-safe container (such as a glass or cup) filled with white vinegar on the top rack of the dishwasher. The vinegar will help break down any remaining residue or oils.
Close the dishwasher door and select a regular or heavy-duty wash cycle (without heated dry) and let the dishwasher run through the entire cycle.
Once the cycle is complete, open the dishwasher door to allow any remaining vinegar smell to dissipate.
By running this initial cycle, you ensure that your dishwasher is clean and ready to use for washing your dishes effectively. After priming, you can start using your dishwasher regularly and add dishwasher detergent as recommended by the dishwasher manufacturer and detergent packaging.
Remember to follow the dishwasher's user manual for proper maintenance and care, as well as loading guidelines to optimize its performance and longevity.
