Grainfather recirculation problem

Hi peeps! After brewing with GF my recirculation system is flowing slower than before. I guess something (probably hops) is inside the tube. I don't know how to fix it. Any advice? Thanks

 

Have you tried removing the ball and spring ?

 

Thanks for your response. I have done it and it is still the same flow rate.

 

How many brews have you done?

How do you clean it after a brew day?

 

That happens after my second brew. During that brew the hop filter came off and when I did the cooling it was partially clogged by then. I cleaned it recirculating hot water for a while but the flow was quite slow.

 

I think there is a way to take the pump apart to clean it, although I'm not sure. I might contact Grainfather direct and ask what to do.

 

I did the same thing. (knocked the filter off) I hooked the chiller up and put the out end of the Clear hose up to the sink,forced hot water through in reverse. (pump turned off of course)
Hope that helps.
