Top 20 Weber Summit E-420 Gas Grill Questions & Answers

That's not unusual at all. Nor, is it a design flaw. The are are air vents all along the back of the grill head that allows rain to get in. Especially, blowing rain. The best solution is to either bring the grill into the garage when it's not in use OR if you don't have a garage, invest a few $$ in a good quality grill cover. Not some cheap $9.99 special. Either one, will solve the water problem, as well as keep the tree drippings and bird droppings off the grill.

Question edited for clarity and spelling 'oraffice' to orifice. Never drill holes! The size of jets is set to very high tolerances by the factory. The burner tube on this is a P-shape which makes it problematical to clean out the spider nests that live in there in the winter. It is a simple system, the gas shoots from the jet and mixes with air in the entrance to the burner tube and burns through the hole in the top. The only other possibility is that the pressure regulator needs adjusting. You adjust it with the burner set on the lowest position to achieve a flame that is low and stable and doesn't go out. https://www.weber.com/US/en/help/schematics/browse/50060001 ..
