Drain Pump Leaking

Hi all. I’ve just replaced my motor and got everything back together. I hit the start button while looking underneath and water started leaking badly from around the drain pump.

I didn’t see an o-ring when taking it off, but it looks as though there should be one. I removed it, checked for debris, and reinstalled it, but the leak persists.

Any ideas?

Thanks.

It’s fixed.

The o-ring had come off of its seat and partially slipped under the plate of the impeller. I reseated it correctly and everything’s fine.
