Tappan Dishwasher leaking
If your Tappan dishwasher is leaking water, start with the most common cause: a bad water inlet valve. When the valve sticks open, the dishwasher can keep filling until it leaks or even overflows. Next, check the center wash arm assembly, lower wash arm assembly, and upper wash arm assembly. A cracked wash arm or a loose wash arm support can spray water at the door or create waves that push water out under the door, leading to a dishwasher leaking from door or leaking on floor. After that, inspect the door seal for tears, gaps, or poor contact, and check the door hinge if the seal looks fine but the door still does not close evenly. A worn detergent dispenser seal can also cause a dishwasher leaking water near the bottom of the door. For a Tappan dishwasher leaking issue, replacing the failed part is usually the fix, since parts like the water inlet valve are not repairable. Enter your model number on RepairClinic.com to find the exact Tappan water inlet valve, wash arm, wash arm support, door seal, door hinge, or detergent dispenser that fits your dishwasher.
01 - Tappan Dishwasher Water Inlet Valve
The water inlet valve opens to allow water to enter the dishwasher. If the water inlet valve is stuck open, the dishwasher will continue to fill with water until the dishwasher leaks or overflows. If the water inlet valve is at fault, replace it. Water inlet valves are not repairable—if the valve is defective, you must replace it.

Do not attempt to seal the crack with glue—the glue will break down in the dishwasher. If the wash arm is intact, make sure the screws in the wash arm support are tight. If the wash arm support is loose, water can spray out between the wash arm support and the lower pump housing, causing waves. These waves can cause water to leak out of the bottom of the door.

05 - Tappan Dishwasher Door Seal
Look for tears, gaps or cuts in the seal that could cause a dishwasher door leak. To determine if the door seal is making good contact, try closing the dishwasher door on a dollar bill all the way around the door. If the dollar bill does not stick, there is a gap in the seal. If the door seal has any gaps or leaks, replace it. If the door seal is working properly but the dishwasher is still leaking, check the door hinges. If the hinges are bent, the door will not close properly, creating a gap between the door seal and the dishwasher. If the hinges are bent, replace them.

06 - Tappan Dishwasher Detergent Dispenser
A dishwasher detergent dispenser releases detergent into the tank during the wash cycle. Some dispensers with a rotating cover, or a latch, have an O-ring or seal that can wear out and allow water to leak inbetween the door panels and onto the floor near the bottom of the door.
