Samsung produces top-of-the-line home appliances that are bought by consumers all over the world. Even though they have a reputation for making high-quality appliances, sometimes things can go wrong with them, and they will need to be repaired or parts in them will need to be replaced.
One of the most common parts of a Samsung dishwasher that needs to be replaced is the drain pump. Thankfully it is quite an easy part to replace and requires limited technical knowledge.
Please note that this guide covers most Samsung dishwasher models, including:
Here’s how to replace your Samsung dishwasher’s drain pump.
- Turn the dishwasher power off by unplugging the cord.
- Turn the water off by shutting off the water supply valve. You also need to disconnect the wastewater hose.
- Make sure that the dishwasher is empty, and if not, remove the water. This will stop water from leaking out when you’re replacing the drain pump.
Remove the Old Pump
- Remove the lower access panel by unscrewing the screws that connect it to the dishwasher.
- Use a 5/8-inch wrench to unthread the water supply line from the inlet valve. When you fully unthread the supply line, water might come out of it, so you might want to put a towel down underneath it.
- Unthread the screws that secure the junction box cover, and then take the cover off.
- Note the location of the wires and then unscrew the wire nuts to disconnect the wires.
- Unthread the strain relief nut and then detach the strain relief from the junction box.
- Disconnect the drain hose from the sink drain or garbage disposal – then feed the hose through the cabinet (if you have one).
- Open the dishwasher door and remove the mounting bracket screws.
- Move the dishwasher out – you may have to adjust the legs on it down so you can remove it from its position.
- Once removed, tip the dishwasher up so that it is resting on its rear panel.
- Unthread the screws on the bottom access panel. Remove the panel and disconnect the leak sensor wire connector. Set the panel aside out of the way.
- Use a small flathead screwdriver to lift the locking tab, and then rotate the drain pump counterclockwise to detach it.
- Remove the wires/connections from the old pump. There you have it! Your old faulty drain pump is now removed.
Install the New Pump
Now that the old drain pump has been removed, it’s time to install the new one.
- Connect the wires to the terminals on your new pump.
- Align the pump on the housing and rotate it clockwise to lock it into place.
- Reconnect the leak sensor wire connector.
- Place the bottom access panel back into place, and secure it by screwing in the screws.
- Pull the dishwasher up so it is upright. Then thread the drain hose back through the hole in your cabinet. Also, make sure that the water and power lines are positioned correctly in their proper channels.
- Push the dishwasher back into place and adjust the leveling legs on it if required to ensure it is level.
- Pull the rest of the drain hose through the cabinet hole and reconnect it. Make sure that the hose is elevated above the connection point so it can operate correctly.
- Reattach the screws into the mounting bracket to secure it to the dishwasher cabinet or the countertop.
- Position the wire strain relief back into its place in the junction box and secure the strain relief nut back on tightly.
- Join the wires back together and secure them with the wire nuts (make sure they go back in the same position as they were when you took them apart).
- Align the junction box cover into its correct position, and then secure the cover with the screws. Make sure they are in tightly.
- Reconnect the water supply line to the inlet valve. Use a wrench to secure it on tightly.
- Place the lower access panel back into position, and secure it back on with the screws.
Restart the Dishwasher
- Now that it is all fixed up, you can turn the power back on at the wall or turn the circuit breaker back on.
- Finally, turn the water supply back on. And there you have it! Your new Samsung drain pump is replaced and ready to go!
- Once you’ve completed the repair, it’s a good idea to run your dishwasher through a cycle to check that the new drain pump is operating correctly.
