Hi all,

I wondered if anyone out there had experience troubleshooting a Bunn Dual DBC. We brewed our first batches this morning and they were fine. Our second brew on the left side (usually our "big batch" side) was terribly weak. Assumed that the filter weight was off and brewed another, same problem. Brewed a small batch on that side and saw the same thing.

The program parameters look fine. The spray pattern and bypass look fine. The right side brews fine, so we are just using the one side for now. Any ideas what might have happened? I will be calling our roaster's equipment guy Monday, but would really like to fix it tomorrow while we are closed. Any ideas?

Hey
It sounds like it could be a temp problem. Have you checked to see if you are getting hot water out of the side that is giving you a weak brew? If it is there are a few very cheap fixes you can try. Each of the brew sides are operated by their own temp control and heating element. You can try to kick the temp dial up slightly and see if that helps.
Brew felt like it was the proper temp, but I'll check to be sure. Thanks. Also, we did check flow rate and it was right on the money.

I'm beginning to feel like this was just part of my crappy morning... nothing was working well. Bad coffee mojo... its no laughing matter.
dbc is a single boiler wouldnt have the problem on just one side some cw series have dual boilers well mostly new ones but Im saying its single cause i dont know if i've ever seen a digi CW

i do believe that there should be more to the model than Dbc is it a Sh, Tf, Cw

check these things 1. amount of water durring a brew (it will be higher with no coffee, coffee soaks up some water) make sure the switch is in right position.
2.Amount of coffee to water is to your brew spec
3.check temp

if you have had this machine a long time might be a valve isnt opening either brew or bypass dont know
hope this helps
Mystery solved. Root cause was a malfunctioning scale - the one we use to portion the beans for our brews. Did a little work on the scale and brews are just right. I guess that problem just lined up in such a way that it looked like the problem was the brewer. Thanks for all the help guys.
