Bunn BT10B Coffee Maker - Page 5 Questions & Answers
Bunn my cafe mcu red light flashing. Water does not heat. Water will run out if brew button pushed, but of course it is cold
I have the identical problem, and I noticed it this morning after there were 2 very brief (seconds) power outages the previous night. Reading around the internet I read that the fuses inside the unit are the likely culprit, and need to be replaced. You can buy fuses made by others, for this unit. But not from Bunn. And there are video instructions around that show how to do it. The fuses are crimped on, not soldered. Mind you, I haven't tried to do this, yet, but that's what I read. Good luck!
My commercial bunn coffee maker is only brewing a half a pot even though I'm pouring in a full pot of coffee water??
Im assuming you tried it more than once and the tank is full when you start? If your doing manual fill pour over the timer has nothing to do with that. If it's plumbed with a water line, before you start changing your timer for the brew cycle, first try the easy fix which is unscrew the spray head. it's the piece the water comes out to the basket. Take the cleaning spring tool and rotate it as you push it thru the tube you just unscrew the spray head from. As your pushing it thru it has two turns in it . Just rotate and push until you have gone thru the second one and then it's clear to the water tank. Unfortunately this doesn't always get it unplugged. Where the tube goes into the water tank there is silicone hub on the part that's in the tank and it can keep some of the lime buildup from being removed. You will have to take the top off and remove the tube to clean it if that happenes. Dont forget to unplug it first. The other common spot for a restriction is where the water leaves the pan your pouring into. You need to remove the pan to get the spray tube out anyway so look also at the big nut that holds the pan onto the tank.sometimes the hole will plug in the center .
My Bunn coffee maker is making weak coffee
Couple of ideas.
Your weak coffee could be due to the machine not getting hot enough, which is usually caused by calcium scale buildup on the heating element (the "burner").
Try descaling with a citric-acid based cleaner, such as Dezcal or Durgol.
The second is the coffee your using is a weak blend. Try changing to a different coffee and see if the strength is better.
