If your Amana dishwasher is leaking from the motor area, start by pinpointing exactly where the water is coming from under the tub. The most likely cause is a failed shaft seal, which is why an Amana dishwasher leaking from pump area or leaking under motor often needs a new shaft seal, seal kit, or impeller and seal kit. If the seal has worn out, water can escape around the motor shaft and show up as a dishwasher pump seal leaking. Next most likely is the pump and motor assembly itself, especially if the motor shaft is rusted or the impeller will not fit correctly. After that, check the water inlet valve for cracks or damage that could cause the dishwasher leaking from motor area symptom, then inspect the drain hose to make sure it is secure at the drain pump outlet and not split or punctured. For the right fix, enter your Amana dishwasher model number on RepairClinic.com to find the exact replacement part for your machine, whether that is a shaft seal, impeller and seal kit, seal kit, pump and motor assembly, water inlet valve, or drain hose.
01 - Amana Dishwasher Shaft Seal
First, try to determine the source of the leak. If the water is leaking from the motor shaft area, the motor shaft seal is likely defective. If the seal is defective, replace it. (Some manufacturers sell the seal independently of the impeller. Other manufacturers require that you purchase the impeller and seal together. Still other manufacturers require that you purchase the entire pump and motor assembly instead of the impeller and seal. It is more cost effective to replace the seal kit rather than the impeller and seal.)

If the dishwasher is leaking water from the motor area, the entire pump and motor assembly need to be replaced. First, try to determine the source of the leak. If the water is leaking from the drain pump, the impeller and seal is likely the cause. On most dishwashers, you can replace the impeller and seal kit independently of the drain pump. However, if you do not want to disassemble the pump, or if the impeller and seal kit is not available separately, you can replace the entire pump and motor assembly. In addition, if the motor shaft is rusted and the new impeller won’t fit onto the shaft, replace the pump and motor asse...mbly.
A dishwasher's water inlet valve opens following a short drain cycle to fill the tank with water in preparation for the wash cycle. If the inlet valve is cracked or damaged, the dishwasher can leak water near the motor area beneath the dishwasher tank.
A dishwasher leak near the motor area could be caused by damaged drain hose. Confirm the hose is secured to the drain pump outlet port and check for any cracks or holes in the hose itself. Replace a damaged drain hose with a new one.
