Ultimaker3 head jam with PVA

[PaulLJ 0]

I just bought an ultimaker3 and an extra set of heads, both AA and BB. I'm putting PVA through the second head which is a BB and it has jammed and clogged the silver part of the head with PVA. I tried the second head and the same thing happened. I took one of the heads apart and cleaned out the silver tube but I think it is the copper head that is clogging. As soon as I tried it again the head was already clogged. I'm using the default settings and made sure Head 2 was PVA. How can the head clog so quickly? Is this a common problem?

I think it is best that you contact your reseller. This is not normal or common.

Taking apart your print cores can very easily damage the heat break, so that is definitely not recommended.
