These are not durable enough to be used in the dishwasher.  I wash all my plastics this way and have never had an issue befofe.  I used a low setting and washed them on the top rack, and now the white plastic insert is all warped and won’t fit until the clear plastic any longer. And the clear plastic container is also warpedbent and the lid no longer fits on top. I bought a bunch of these total waste of money.
