Sump Gasket

#1 rule, make sure you valve off the water before removing any hoses. Remove wire trays inside dishwasher and then pull out dishwasher far enough to disconnect water line and power cord. Remove center piece and screen covering sump inside the dishwasher. Turn dishwasher on its side and remove hoses to sump and pump. Disconnect power to sump pump. Loosen retaining nuts that secure the sump and remove. Replace old gasket on sump with new. Turn dishwasher upright. Be careful with placement of new gasket when reinserting sump so that the gasket doesn't come out of position and the sump is centered properly. Secure with retaining nuts from bottom. Reconnect power connector and hoses to sump. Pour enough water into the dishwasher to verify gasket doesn't leak... look with flashlight under dishwasher for signs of water dripping from sump. Reinstall screen and centerpiece in sump inside the dishwasher. Reconnect water line and power cord. Run through wash cycle while monitoring for leaks under dishwasher. Reinstall wire trays.

Piece of cake as long as you get the gasket installed properly and the sump centered correctly... do not overtighten the retaining nuts or it may force the gasket out of position when the screen is secure with the center locking piece over the sump.

First point of leakage was the door. Turns out that a gasket at the bottom of the door functions as a wave trap. As the bottom sprayer spins it sprays against the door and creates a small wave of water this gasket was starting to disintegrate, it was letting water surge over the small tray at the doors bottom. Easy to replace just pull down and remove press fit on inside door bottom. Only when this was replaced did I find the real leak but not until I guessed at the tub seal as the leak. Very hard to see where the water really comes from! Turns out it was not the tub seal but a clip that holds the heater element got smashed down from a dropped dish rack at some earlier time and this caused the heat to increase at the clip and eventually heat the clip to extent it melted the tub directly under it. JB Weld to the rescue and we have a waterproof tub again. Well almost! The tub gasket resisted my best efforts to seat correctly and thus required a new tub gasket, still hard to seat but after 2-3 attempts we have a winner. Total cost about 50 bucks vs. 6-700 for a new unit. Wife is happy!!
