If your KitchenAid washer is leaking, first inspect the drain pump, especially if the water is coming from underneath the machine. A cracked pump, damaged housing, or worn pump bearings can cause a washing machine leak, and the drain pump must be replaced rather than repaired. Next, check the washer hoses, including the tub-to-pump hose, for cracks, loose connections, or other damage. A leaking tub seal is another common cause of a washer leaking from the bottom or washing machine leaking underneath. If the seal has allowed water into the tub bearings, replace the tub seal and bearing kit, since this repair requires significant disassembly. Also confirm the dispenser drawer is fully closed and not cracked. On a front-load washer, using the wrong detergent or too much detergent can create excess suds that escape through the overflow system and cause a front load washer leaking problem. Unplug the washer and shut off the water before inspecting it. Enter your model number to find the exact KitchenAid replacement part for your specific washing machine.
01 - KitchenAid Washing Machine Drain Pump
The drain pump pumps water out the drain hose. If the drain pump is cracked or damaged, or if the bearings are worn out, the drain pump may leak water. The drain pump is not repairable—if the pump is leaking water, replace it.

Hoses apart from the fill hose or drain hose could be reponsible for a leaking washer. You should inspect all of the appliance's hoses, such as tub-to-pump hoses, for damage or loose connections and replace if necessary.
03 - KitchenAid Washing Machine Tub Seal and Bearing Kit
The tub seal might be torn, causing water to leak from the seal. If the tub seal is leaking water, water may leak through the tub seal and into the tub bearings. This can cause the bearings to fail. For this reason, if the tub seal is leaking water, replace both the tub seal and the tub bearings. Be aware that this is a complicated repair and will require disassembling most of the washer.

If a washer is leaking water, you should confirm the dispenser drawer is completely closed and free of damage. If the drawer is cracked, the component could be responsible for the leak and should be replaced.
If you have a front-load washer, be certain that you are using an HE - high efficiency - detergent. HE detergent is formulated to be low-sudsing and to be used with the lower water levels utilized by front-load washers. Front-load washers have a small overflow system usually on the back of the appliance. If you have too many suds, they are probably escaping from there.

07 - KitchenAid Washing Machine Transmission
Since the transmission shaft extends into a top-load washer's inner tub, a transmission bearing or tub seal that is damaged could potentially cause the tub to leak near the motor area. For some models, these components may only be sold as an assembly, you may need to replace the entire transmission assembly to solve the leaking problem.
