Hello, my name is George.. Kindly be patient whilst awaiting responses, I'm not constantly available.Are you meaning the area that looks like the grill of a radiator, and if you look down through there then you see galvenised steel?
Just inside the hinges of the glass cover on both sides there is a slightly raised area that has slots cut into it. I don't think they actually serve any function, but food has gotten inside them. Is there an easy way of getting at it?
That area is for the spring that controls the fall of the lid section... When clogged with food or other debris I usually cover the area with a towel so as not the get water where it should not be and then either use a steamer or a washing liquid bottle filled with warm water to flush the area
Ok george thank you..
