What Causes A Dishwasher To Leak?
Dishwasher Leak From The Bottom
This is one of the most common places you’ll notice your dishwasher leaking from. If you notice your dishwasher leaking from the bottom, the culprit is usually either the water pump or the water inlet valve.
The seal on the water pump wears out in time because it is made of rubber. You will know if the water pump seal needs changing if you notice water dripping from the motor or the pump housing.
The other cause might be the water inlet valve. Remove the bottom plate on the front of your dishwasher and check if there is any drip coming from the top of the valve. While you are there, check if there is any corrosion or hard water element of the valve. If there is any issue with this, turn off the water source and replace it.
It is something leaking under the tub. The most common components to leak is the water pump seal and or the water inlet valve.

You can clean the air gap from any waste getting stuck and clear the drain line. Also, disconnect the hose and flush it out.
