In a typical washing machine, when you put detergent into the detergent compartment or dispenser, it does not fall through the holes at the bottom. The detergent compartment is designed to hold the detergent until it's needed during the washing cycle.
When you turn on the washer and start a cycle, the machine's internal mechanisms will release the detergent at the appropriate time during the wash cycle. Most washing machines have a water inlet valve that allows water to fill the drum, and the detergent is mixed with the water to create a soapy solution. The machine agitates or tumbles the clothes in this soapy water to clean them effectively.
If you notice that the detergent is falling through the holes at the bottom of the compartment before the washing cycle starts, it might be an issue with the dispenser or the design of the washing machine. In such a case, you may need to contact the manufacturer or a professional technician to inspect and fix the problem.
