I replaced the drain pump on a Samsung dishwasher that was leaking. First, I carefully disconnected the power supply to ensure safety. Next, I removed the bottom access panel to access the internal components. I then located the faulty drain pump and detached it from the dishwasher's housing. After removing the old pump, I installed a new one, ensuring all connections were secure. I reassembled the dishwasher, checked for any leaks, and restored the power supply. The dishwasher was tested to confirm the leak was resolved, and the unit was functioning correctly. The job was completed efficiently, ensuring the dishwasher operates without issues.
