Las leyes obligan al vendedor a entregarle al comprador, junto con el producto, el manual de instrucciones Whirlpool MAH3000. La falta del manual o facilitar información incorrecta al consumidor constituyen una base de reclamación por no estar de acuerdo el producto con el contrato. Según la ley, está permitido adjuntar un manual de otra forma que no sea en papel, lo cual últimamente es bastante común y los fabricantes nos facilitan un manual gráfico, su versión electrónica Whirlpool MAH3000 o vídeos de instrucciones para usuarios.

- marcas de seguridad y certificados que confirmen su concordancia con determinadas normativas

¿Por qué no leemos los manuales de instrucciones?
