Why did my water pump come on and will not stop?
The water pump on my J5 came on in the late hours of the night *by itself*. It constantly runs. Why did the pump come on 12 hours after the machine was turned off? A short?
At this time, the pump runs when i turn the power on. The display shows “warming” until the water in the tank runs out. The brew group has been maintained and the water is draining into the grounds container. Cleaning/descaling current.
So, what phantom is in my machine? What gives the pump instructions?
