What does Schaerer Over current brew motor mean?
A motor moves the brewing unit through its cycle: filling, pressing, brewing and ejecting the used grounds. The machine measures the motor current. When the brewing unit works against something hard, a jam or too much friction, the current rises. When it goes above 4 amperes, the machine shows Over current brew motor. The manual gives two causes: the brewing unit draws over 4 A, or the brewing unit is jammed. The step for an operator is to check the brewing unit for anything stuck, such as compacted coffee or an object in the mechanism. The message is not about the water or the grinder, but about the mechanical load on the brewing unit. If the unit is clear and the message returns, the motor, the gearing or the unit itself may be worn and needs a technician.
