Realign the dome

Line the dome up again

Springs off first, dome open, helper holding it. The two hinge springs carry the dome's weight. Every Big Green Egg method takes them off with the dome fully open before any band or hinge nut is loosened (BGE UK). No BGE document warns about it, but owners report a dome whipping open, and one was hit in the face when a band slipped (owner report). The dome and base are heavy ceramic (99 kg together): work with two people. A dealer can do it for you, and BGE UK offers paid servicing.

BGE UK's how-to.

1. Open the dome and take both springs off.
2. Close the dome and remove the side brackets: the dome now moves.
3. Move the dome until all the holes and the front marks line up.
4. Tighten the brackets (7/16 in) and check the rear nuts (1/2 in) are tight.
5. Open the dome and refit the springs.
6. Close it and check all round for gaps (owners slide paper round the rim); repeat if needed.
