Posted Sun Feb 23, 2014, 2:15pm Subject: Bunn G9 Grinder Timer Bypass
I have a Bunn G9 grinder that I use for my morning drip coffee every day. Iíve found that Iím constantly messing with the timer trying to get a consistent amount of coffee (by weight). The amount that it spits out varies as much as ľ ounce from day to day and when I switch to a different type or roast of beans I spend the first few days trying to get the timer set close and then tweak from there. Bottom line is that I would like to bypass the timer altogether and grind into a container on a scale. I have a copy of the wiring diagram, but Iím not smart enough to figure out how to bypass the timer. Has anyone done this or can you tell me from looking at the diagram below?
The easiest way is to weigh the beans before you grind them and then only put that ammount into the grinder. The G9 is designed to use the same coffee day after day, not changing, for commercial use. When operated this way it is a very consistent grinder but as you noted, it will grind different volumes with the same time depending on the beans and the grind settings.
They are very good grinders (I own a G9HD2 and a LPG) when used in the intended market they were designed for but when geeks want to change coffee on them then there is a bit of an adjustment needed each time as you found out.
Simply weigh before grinding, place that volume in the grinder and grind everything you put into it. There should be very little grind retention so what you put in you should get out.

Thanks for the reply. I hope I didn't sound like I was complaining about the grinder - I love it. I just thought if there was a simple way to bypass the timer, it would work even better for me. I decided what I would do is to just crank the timer all the way up, put the scale underneath and see if I could stop it when the weight was right. It worked great this morning and I was able to turn it off exactly at the 3 oz of grounds I was wanting.
