My washer has started leaking. I removed the outer shell and started the washer. There was no leak as the tub filled. After the agitator started I saw a drip coming off a brace on the back of the frame, just under the tub. The brace is shaped like a channel and I could get my finger in the channel. I THINK the tub seal is leaking. Can you tell me if this is a reasonable assumption and what parts I might need to repair it.

Thanks,
Philip
