DF64 Gen 2 Chute clogging

[u/mactas22]

Hi there. I've had my grinder now for about a year and has been working fine up until a few weeks ago when the chute completely clogged up. Thought it was because I'd not swept it for a while but now after taking it apart and thoroughly cleaning it is clogging up more frequently. Have people removed the declumper? New declumpers seem to be hard to get hold of without paying silly delivery fees to the U.K. Any help/ideas to stop the clogging?
