there is a rubber bowl under the washer where the recirc and drain is, it gets filled with food stuff, especially rice. i found this out when mine would not drain, it had orange seeds stuck in it, cleaned it out and ran two cycles with vinagre and it seems good as new. once every month i run a vinagre cycle in it to keeep it clean.
