If your Samsung dishwasher is leaking from motor area parts under the tub, start by pinpointing exactly where the water is coming from. In most cases, a dishwasher leaking from pump area is caused by a worn shaft seal or a dishwasher pump seal leaking at the motor shaft. On some models, that means replacing just the seal kit, while others use an impeller and seal kit. If the seal is bad and the shaft is rusted, or the kit is not sold separately, the full pump and motor assembly is usually the fix. After that, check the water inlet valve, since a cracked valve can cause a Samsung dishwasher leaking under motor symptoms, and inspect the drain hose for cracks, holes, or a loose connection at the drain pump outlet. A Samsung dishwasher leaking from motor area is usually fixable with the right part and a careful inspection.

01 - Samsung 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.
