What can I do if my grill doesn't ignite?

First check if the burner, the gas valve, and hose are free from dust, and then if the gas valve on the gas bottle is open. If your grill has a piezo ignition, you can easily check whether the defect is in this piezo ignition. If you can light your barbecue with a long match, it is likely that the piezo ignition is defect.
