No, you do not need to manually wash the dishes before putting them in the automatic dishwasher. In fact, doing so can interfere with the dishwasher’s cleaning performance and may cause damage to the machine.
However, if you do choose to manually wash the dishes before placing them in the dishwasher, it’s important to avoid using any cleaning chemicals, as these can interfere with the performance of the dishwasher’s cleaning chemicals. Additionally, if you are soaking the dishes before placing them in the dishwasher, be sure to rinse off all detergent before placing them in the machine.
In general, it is best to remove any excess food debris from the dishes before placing them in the dishwasher rather than manually washing them. This will help ensure that the dishwasher is able to clean the dishes effectively and efficiently without any interference from outside cleaning agents or residue.
