If your Amana dishwasher’s leaking water, follow these seven troubleshooting steps to help you isolate where the leak is coming from so you can repair or replace the defective part or parts and get your dishwasher back to functioning properly again.
WARNING – If you are attempting to repair any dishwasher yourself, be aware that you are working with potentially dangerous electrical currents that can cause serious bodily injury or death. Always remove the electrical power source from the appliance before you ever begin working on it. If you are attempting to repair any household gas appliances yourself, always be sure to turn off the gas that is designated to the appliance before you ever begin to repair it. Be aware that dishwashers have extremely sharp edges and moving parts that can cause serious bodily injury or death. Be aware that there are many other dangers and precautions involved with a dishwasher repair besides those listed above. We strongly suggest that you please read our DISCLAIMER before any further actions are taken or proceeding any further. Think safety first!
Step – (1.) Door Gasket
If your Amana dishwasher is leaking water from around the door, you will need to troubleshoot the dishwasher’s door gasket. Is the rubber dried out and getting hard? Visually inspect for rips, tears or small holes in the gasket seal and replace the door gasket if any of the mentioned damage is found.
Step – (2.) Water Inlet Valve
Inspect the water inlet valve. If the inlet valve is stuck in the open position, the valve will over fill the dishwasher and cause it to leak water through the door. If the valve is stuck in the on position, you will need to replace the valve to fix the problem.
Step – (3.) Hoses
Inspect all of the hoses, hose ends and hose clamps. Are the hose ends all connected securely with the clamps? If you see any corrosion or white calcium build up around the hose clamps, this is a good sign of a leak. You might be able to tighten the clamp, but it is best to replace it with a new one. Be sure that you turn the water off to the dishwasher before removing any hose clamps or hoses.
Step – (4.) Wash Arm
A cracked or damaged dishwasher wash arm could be the reason why your dishwasher is leaking water from around the door. Inspect the wash arm for damage and replace it if any is found.
Step – (5.) Pump Gasket
If there is water leaking from the center bottom section of the dishwasher, you will need to examine the pump gasket for leaks. If it is not leaking, examine the sump seal and motor shaft seal and replace if they are leaking. If you have diagnosed that the pump gasket is faulty, it will need to be replaced with a new gasket.
Step – (6.) Sump Seal
If water is leaking from the center bottom section of the dishwasher, you will need to examine the sump seal for leaks. If it is not leaking, examine the pump gasket and motor shaft seal and replace if they are leaking. If you have diagnosed that the sump has a faulty seal, it will need to be replaced with a new seal.
Step – (7.) Motor Shaft Seal
If you can see that water is leaking from the center bottom section of your dishwasher, you will need to visually inspect the motor shaft seal for leaks. If it is not leaking, examine the sump seal and pump gasket for leaks and replace them if they are leaking. If you have verified that the motor shaft seal is bad, it will need to be replaced with a new seal.
