Pellets in the hopper become swollen, crumble, or form clumps; the grill struggles to stay lit.

Safety first: Turn OFF and unplug the grill before handling pellets.

• Empty the hopper: Remove all pellets and vacuum out dust and fines.
• Discard bad pellets: Do not reuse swollen or crumbly pellets; they can jam the auger and cause flame-outs.
• Inspect the hopper lid seal: Check the Nexgrill hopper lid gasket and hinges. Replace the gasket if it does not seal tightly.
• Use dry storage: Store pellets in a sealed container indoors and only load what you will use in the near term.
