Strange green greasy stuff on dishwasher filter
The filter of my dishwasher get a coat of green/grey greasy stuff on the filter. (see pictures)
It is not from the food it rinses.
It looks like it comes from the inside of the dishwasher.
The dishwasher works perfectly, dishes are clean.
If I clean the filter, after a while the greasy stuff is back there.
The dishwasher is an Electrolux ESF 6243
I tried asking Electrolux but they said they never heard of it
My fear is that it can be some dangerous substance.
Thank you for the help.
