Hi ruthie.
Thank you for reaching out regarding your Samsung 6.0 cu. ft. Front Control Slide-In Gas Range with Convection & Wi-Fi, Fingerprint Resistant if grates can be put on the dishwasher. Regarding your concern based on the user manual, we should clean the grates.
Turn off all surface burners and make sure they have all cooled down.
1. Remove the center burner griddle(C)
following both sides grates. (L/R)
2. Remove the burner caps from the burner
heads.
3. Remove the burner heads from the
valve manifolds to reveal the starter
electrodes.
4. Clean all removable grates, griddle, and
burner components in warm, soapy
water. Do not use steel wool pads or
abrasive cleaners.
5. Rinse and dry grates, griddle, and burner
components thoroughly
6. Return the burner heads to their
positions on top of the manifold valves.
Make sure a starter electrode is inserted
through the hole in each burner head.
7. Return the burner caps to their positions
on top of the burner heads. To ensure
proper and safe operation, make sure the
burner caps lie flat on top of the burner
heads.
8. Reinstall the burner grates and griddle in
their respective positions.
9. Turn on each burner and check if it
operates properly. After verifying that a
burner operates normally, turn it off.
I will be sharing the user manual for further assistance. Please go to page 36-37.
