Move your GE Triton XL dishwasher away from the wall, and disconnect the power supply from the AC wall outlet.
Open the front dishwasher door, and then remove the top and bottom racks so you have access to the inside of the unit.
Turn the drain filter, which is located at the bottom center of the unit, counterclockwise, and then completely remove it.
Use a rag to help remove any excess food or dirt, or any other items clogging the drain. Tighten the filter back in place by turning it clockwise.
Use a screwdriver to remove the two screws on the front panel, and then take off the front panel. Set it aside.
Press down on the clamp located next to the water pump and hose, and then loosen the hose from the pump. Remove the hose completely from the dishwasher unit.
Spray the inside of the hose, using a garden hose to remove any obstruction clogging it. Reconnect the hose, making sure it is securely fastened.
Reinstall the front panel on the unit and then reinsert the two screws. Close the dishwasher door and reconnect the power supply.
