My EX6 is taking forever to reach 600 recently. 25 minutes at best and sometimes can't get over 475 before I give up. It seems to be burning through a ton of pellets while trying to reach temp also. Before installing the new welded auger assembly and pellet hopper slide I was getting to 600 in 15 minutes easy. I had switched pellets to B&B Championship Blend and thought that might causing trouble so emptied them all out and cleaned the SF thoroughly. I removed the auger and motor and cleaned out any pellet dust I could find. I've made two attempts with weber smokefire pellets now to reach 600 and still can't get over 480. Still on Firmware 4035. Not sure what else try. Anyone have any suggestions?
