Like new Hyber H13 coffee machine, used for three months (All its accessories are new in the box and have not been used) It has a malfunction when turned on, it shows error code E-6 and does not work I don't know the cause or type of malfunction, this is the only issue. Other accessories and the body are clean and new. Note its features: Espresso temperature control Steam pressure and boost control Touch screen Display for bar pressure
