I built the grill yesterday & noticed that when I tightened the bolts that connect the ash/grease holder to the front legs, the enammeled metal bit wasn't quite long enough.
So when I fully tightened them, the metal bent a bit & the enammel came off.
I contacted Weber with a couple of photo's and they are sending me a new part. Result.
I mentioned that with the motor having a 'Rev D' sticker, please could they also send me the updated chute, motor & auger (Auger Chute (Part 69374), Hopper Insert (69230), Plate (69377)), their reply just now was:
I replied back mentioning the Rev D etc & I'll report back as to what they say.
For info here are the pics I sent Weber
