bought a new new coffee machine (Mr coffee) , washed and ran water through a few times , still getting oily film on the surface of coffee , any ideas?

Vinegar

With a batch of coffee or still doing initial rinse?

How does it taste? Mmmmmm, oil.

^^^^^
This should work. If it doesn’t I’d take it back.
I run white vinegar through my coffee pot every now and then anyways.

i rinsed several times , have made several batches with same coffee . why vinegar? it's brand new.

tastes good

coffee has oil in it

yes . but didn't have this issue with old coffee maker.

This and it is more noticeable if you are grinding your own beans(fresher).

DDT or paraquat on the beans.

Columbians piss on the beans for American consumption.

Does built up old coffee crud absorb oil?
Maybe, idk

It’s possible that some of the coffee maker components could have some kind of residue on them from the manufacturing process. Also, mineral deposits can collect from using water from some sources, Using the vinegar periodically will help with removing that.

First try a completely different coffee. Also check and see if this machine puts out hotter water than the old one. If it were me and I knew I had the machine clean and used good water I would just drink it if it tastes good.

I’d pour some oil in it and see if it has the same sheen.

i'll make another pot and post pictures later on.

A first world problem.

I would not drink an espresso unless it had
oil on the surface in the form of crema.

You say that like it is a bad thing.

Hard water separates the oil

why should i feel guilty? i am worried about what i eat and drink. aren't you? please google it and paste it.
