My bunnomatic commercial coffee maker is overbrewing by about 2 cups. how do i adjust the water flow?

I know that most grocery stores sell a "cleaner" or two next to their coffee filters/coffee makers/kitchen appliances section. These are usually heavily acidic, and will do a great job of cleaining your coffee maker. I've always been wary of acid in my coffee though, so I just use white vinegar. It'll do a decent job of cleaning out the coffee maker. Run a 1:1 mix of water and vinegar through your coffee maker, drain it, then run water through at least twice.

Scaleing/deposits building up in a coffee maker are signs of imperfections in the water. All tap water has it, but if you don't want to worry about it, use bottled or filtred water in your coffee pot. Plus, your coffee will taste better!

If you have a specific problem, Let me know I can help.

Hello. Here is the owners manual for your unit that tells how to clean and delime your machine, if it requires parts, it looks like you will have to contact a local servicer, or Bunnomatic.

follow the instructions for first setting up the unit, as most, if not all the water has evaporated by now. Don't plug it in yet :)

if not you can go to www.bunnomatic.com and download the appropriate manual, there is a link on the left side of the page, click and choose your unit.
Hope that helps, and thank you.

Hello. First , I don't find your Model at Bunnomatic.com, and I have worked on Bunn machines for over 21 years, and don't recall a unit by the Model information you provided. However, from your description, it sounds like you have one of these, single units, here:
http://www.bunnomatic.com/pages/techdocs/manuals/satbrew.html
scroll down for the parts/service manuals. The problem you describe has 3 possibilities, one is a water pressure/flow problem, caused by a clogged filter, or too small a supply line with too many units all on the same pipe, try only brewing when nothing else is drawing water. Second is scale build up at the tank fittings for the brew solenoid, build up in the hoses, tubing, solenoids, etc. all of which require cleaning. Third is an actual problem with the timer, or the setting switch. It is always cheaper, if you can do the work yourself, and check the first two items, then you can move to an actual part problem. If you have further issues, just ask.

Hopee that helped, and thank you.

Hello. I would say that you are going to have to call: For repair information, call 800-352-286. They don't usually supply commercial repair houses with part information, or you could try here:

They will be able to get you what you need with minimal effort.

Hope this helped, and thank you.

Hello. I need to know if you have an automatic unit, or a pourover. The pourover will not have a timer at all. The difference is you have to pour the water in to get coffee out, an automatic would be connected to a water line, and you just push a start button. If it is an automatic unit, there has to be a timer somewhere to adjust the amount. Here is a web address that has your manual, and a parts breakdown should you need to find where the timer is located.

It's probably time for a good cleaning. Follow the procedure in the manual, or get some commercially available coffee maker cleaner. When the minerals build up enough, the water flow and heating is reduced enough to keep it all from passing through.

Please take a moment to rate this solution if it's what you needed, and thanks for asking here!

If this problem started after moving the machine, pull the machine out a little & look behind it for a kink in the tubing coming to the brewer. These brewers time the water coming through them, so if a kink is restricting the water flow, running the same amount of time equals much less coffee in the airpot.
