If your VacMaster VP215 vacuum sealer is smoking, it may indicate a potential issue that requires attention. First, check if there is any debris or food particles stuck in the sealing bar or heating element, as they can cause smoke when heated. Ensure that the machine is properly lubricated according to the manufacturer's instructions, as inadequate lubrication can also lead to smoke. If the issue persists, it is recommended to contact VacMaster customer support or a qualified technician for further assistance and troubleshooting.
