For a top-load washing machine, the placement of liquid detergent depends on whether your machine has a detergent dispenser or not:

• If your top-load washer has a detergent dispenser:
  Locate the dispenser, which can be a pull-out drawer or a compartment along the top edge of the tub. Add the liquid detergent there before selecting the wash cycle and starting the machine. The detergent dispenser is usually the largest compartment and may be labeled. This method ensures the detergent is dispensed at the right time during the wash cycle

• If your top-load washer does not have a detergent dispenser:
  Pour the liquid detergent directly into the empty drum or tub before adding your clothes. It is best to add the detergent first, then start the water fill, and finally add the laundry. This helps the detergent distribute evenly throughout the load as the water fills the drum

Additional tips:

• For detergent pods, place them at the bottom of the drum before adding clothes to ensure they dissolve properly

• Always follow the detergent manufacturer's recommended amount and instructions for your specific machine

In summary, the safest and most common practice is to add liquid detergent either into the designated dispenser if available or directly into the empty drum before loading clothes and starting the wash cycle. This ensures optimal detergent distribution and cleaning performance.
