if that leak is coming
from that stainless steel clamp with the phillips head screw then it's not leaking thru the main pump seal which is lower than that bracket. that main pump seal is below the drain impeller which sits below where that drain hose connects into the pump housing. so looks like you are in luck!
if it were me i would take off the bowtie by removing the 2 bolts, remove the drain hose (gently) from the pump housing. i say this because i have heard of the drain ports breaking off pump housings from old g.e. machines. i would disconnect all electrical wires from the motor, red, yel, blk, blu from your wiring diag above, and then loosen that clamp and remove the motor/pump unit.
as said above that pump impeller is pressed on and the seal is underneath so it's not something you can easily check. but it's not leaking there so just let it be! put it in a safe place and then look for ways it is leaking around that clamp/boot area.
i admit i have never taken the motor/pump off mine due that so far mine doesn't leak. but i would suspect that leak is due to either some problem in the clamping of the pump to the housing. take some pics of it and post for us, maybe we can help more.
and while i had that motor off i would spray a good dose of wd-40 right in that pump housing so it will get down to the seal itself.
look forward to your next post. these machines are so nostalgic, this is making me get mine back out of storage. gonna run it this week! good luck!
