Bunn Dual Brew Troubleshoot and Calibration

Customer having issue with brewing the full amount of coffee they need. Calibration test shows a smaller amount of water comes out than the machine thinks. Solution is to address scale blockage in brew valve (or replace) and recalibrate by making sure the amount shown on display matches what is dispensed.

Thank you John! I have been struggling with my Bunn DBC for months now and your explanation of how to remove and descale the solenoid really helps, I will be attempting this sometime this week.

Thanks for the info have you ever came across the bi pass valve leaking from the right side hole ?

What's the water temperature? And what's the coffee/water ratio?
Thank you.
