May I ask why your trying to find compatible models for the part numbers you request, since alot of the time the model numbers have variants and some times the part may fit some models but not all variants?
In terms of the part, the part number is: FM20KCGB
It fits the following Indesit models: DIM KCA IX GB, DIM KA IX GB, CIM KCA IX GB, CIM KA IX GB, BIMS KAB IX GB, and BIMS KA IX GB
From what I can tell it will also fit select models from Creda, Hotpoint and Ariston, if you have model numbers in mind I can certainly check compatibility for you.
So I can resolve the case, appreciate if you can login and rate the service using the star rating on the page.
