Whirlpool Dishwasher Leaks :(

Okay guys… please help.

our whirlpool is only 18 months old, this is the one that we got with our house. Of course, it’s out side the warranty.

Just this week, we noticed a puddle of water infront of the washer during cycle and the dish never gets clean. we took apart the bottom panel, noticed there are water coming out of the motor area. we called a local appliance repair man, he said the whole motor needs to be replaced and it might be better to look at new dishwasher. Could it really be the motor? or is it just something i can try to repair myself? i’m not very handy, but i just can’t think it’s the motor,

i found a diagram online and water is dripping from part #28 on the chart.
please help…
