I would suspect two things.

The container is not completely clean.  That mean absolutely no soap residue.
In fact I normally do not recommend cleaning the contain with soap or anything
else, it will add more contamination than it removes.

The quality of the distilled water. Are you using the same brand?  I have found
some brands to be very variable in quality from batch to batch.  If that is the
case you may try a different brand, and if you have to find a batch of a brand
that works, and stock up on that batch number.
