The inlet sump in your GE dishwasher model GSD6660GSS is attached to the bottom of the dishwasher tub. Its main purpose is to collect water for the pump. Puddles underneath and around your dishwasher are the most common symptom of a faulty inlet sump. Replacing the part is the only way to stop the leak from damaging your appliance and your kitchen floor.

How to Replace an Intel Sump in Your Dishwasher

During any type of appliance repair, safety should be your number one concern. That being said, before you swap out the old inlet sump for a new one, unplug your dishwasher and shut off its water supply. Safety goggles and work gloves should always be worn while you work on repairing an appliance.
  1. Start your repair by disconnecting the fill line and drain hose from underneath your sink. Place a towel down to catch any water that drips out. The fill line is connected to the hot water valve. To detach the line, use a 5/8″ wrench. Once you have removed the fill line, grab your 5/16 ” nut driver to loosen the clamp securing the drain hose. After you’ve created enough slack, pull the hose off the drain or garbage disposal.
  2. Open your dishwasher door and take out the lower rack. To remove the spray arm from the locking hub, lift it up and rotate it counter-clockwise. After the spray arm is out of the way, take out the locking hub and remove the fine filter by pressing down and then pulling up on it.
  3. Disconnect the water supply line from the spray arm base by disengaging the locking tab on the side of the supply line. Once the line is no longer attached, rotate the base counter-clockwise to remove it from the dishwasher tub.
  4. The filter that covers the inlet sump is now visible. Before you can remove the filter, you’ll need to release the filter cover. On each side of the cover you’ll find two locking tabs. Using a flat head screwdriver, push on the tabs facing you, and pull the cover off the filter. Now squeeze the locking tabs on each side of the filter and lift it up. Once the filter leading to the inlet sump is out of the way, you can remove the coarse filter by simply picking it up and taking it out of your dishwasher.
  5. Unthread the mounting screws that hold the dishwasher to the countertop. Then, pull the dishwasher from underneath the cabinet. Place a towel on the floor, and carefully lay the dishwasher on its side.
  6. Find the drain pump, and disconnect the wires running to its terminals. Loosen the clamp securing the drain pump to the inlet sump with a 5/16″ nut driver. Next, unthread the nut that holds the drain hose on the drain pump, and pull the hose off the pump. Remove the screws securing the pump to the dishwasher frame and lift the drain pump out of the inlet sump. Take off the clamp that holds the sump and drain pump together.
  7. Now you can remove the sensor from the inlet sump. Loosen the clamp securing the sensor to the sump with your nut driver, and pull the sensor out of the sump. Don’t forget to slide the clamp off the inlet sump and set it aside.
  8. Disconnect the inlet sump from the circulation pump. First, loosen the clamp and then unthread the screws holding the upper and lower sump brackets onto the dishwasher frame. Finally, remove the inlet sump from the dishwasher tub and the circulation pump.
  9. Grab your new inlet sump, and slide on the clamp that secures the connection between the circulation pump and the sump. Attach the sump to the circulation pump, and line up the inlet sump with the opening in the dishwasher tub. Reconnect the upper and lower brackets to the tub frame and tighten the clamp holding the sump and circulation pump together.
  10. Before reinserting the sensor, slip the clamp you removed earlier back onto the inlet sump. Push the sensor into the sump and tighten the clamp to ensure the sensor does not fall out.
  11. Place the drain pump clamp back on the inlet sump before reinstalling the pump. Push the pump into the sump, and reattach the mounting screws to secure the drain pump to the dishwasher frame. Slide the drain hose onto the pump, and tighten its clamp to guarantee the connection is secure. Reconnect the drain pump wires to the pump terminals
  12. Stand the dishwasher up and feed the fill line and drain hose back through your kitchen cabinet. Then, push your dishwasher halfway underneath your counter. Once your appliance is in place, open your sink cabinet and pull on the fill line and drain hose to ensure they aren’t caught on anything. Stand back up, and finish pushing your dishwasher under your counter. Secure your appliance to the cabinet with the two mounting screws you removed earlier.
  13. Go back underneath your sink, and reattach the drain hose. Use your 5/16″ nut driver to tighten the clamp on the hose. Next, reinstall the fill line to the hot water valve with your 5/8″ wrench.
  14. Open your dishwasher door and start reassembling the inside of your appliance. First, put the coarse filter back in, and then reinsert the filter that runs to the inlet sump. Make sure the filter snaps into place before you reinstall the filter cover.
  15. Now screw the spray arm base back in and reconnect it to the water supply line. Once the base is secure, put the fine filter back on, and reattach the locking hub to the top of the spray arm base. Push the spray arm onto the spray arm base, and rotate it clockwise. Finally, insert the lower dish rack and close your dishwasher door.
  16. Plug-in your dishwasher and turn on the appliance’s water supply. To test your newly repaired dishwasher, fill it with a load of dirty dishes and run them through a wash cycle. If your floor is puddle free at the end of the cycle, your repair was a success.
