This may be due to improper cleaning of the cooking plates.
We recommend that you pre-wash your cooking plates in the following manner before putting them in the dishwasher to remove any food residue:
- Soak the plates in hot water and degreasing dish soap for about 30 minutes,
- Scrub both sides of the plate with a sponge or a dish brush, hot water and degreasing dish soap,
- Put in the dishwasher.
