I believe you may have a Tub Seal Leak you will need to remove the Outer Tub to start of the repair process for a Tub Seal replacement.
I would start by removing the clutch I feel the water will coming down the Spinner Assembly support and or the agitator shaft driving the transmission.
See this post Clutch Fix
for removing the clutch and inspecting and re-lube of the One-Way Roller clutches bearing.
You will find links to the Service Manual at that post.
Read this post1
and this post2
for removing the Outer Tub Bearings and seals and special tool to remove Spinner Assembly.
No doubt this is a big job but other DIY’ers have done if you can tolerate the down time.
I feel repair cost will trigger a washer replacement if a DIY fix is not an option for you.
I’m an owner not a repair person but have some hands on with the FAV6800A and have helped owners/repair folks out with FAV9800A LCD version of this machine…..Rich
