SOURCE: Bunn Coffee Maker Leaks out the bottom

Hi I have had this problem twice....this time I took off the top of the maker to check it out and noticed something loose and this fixed the problem, on mine at least. Lift the lid and take out the two Phillips screws, and remove the grid. Take out the three (or four) Phillips screws on this level and remove the top of the maker. There is a tube, with a hex nut around it, under the swivel arm that shuts off the water when the lid is up. On my maker this nut was very loose, even though the seals were still good. I tightened it with a pair of pliers( don't over tighten) and it hasn't leaked since. I also cleaned the water tray out while I was at it , as it looked rather yechhy. Reassemble and put the screws back in (don't over tighten, as they are in plastic)

If the brewer heats the water but it doen not dispense this is probably because air is trapped in the tubing of the water system.

To solve, use as air compresser with minimum pressure (20-25 psi) and force air through the system using an air nozzle that is long enough to reach into the hole into the area where you fill the water. Place your hand under the dispenser and ensure you can feel the air from the compressor coming through.

Once you clean out the lines, you should be good to go.

We have had our coffee maker sitting on our shelf "broken" for months now. We tried this last ditch effort before tossing the machine in the trash and low and behold it worked! :)

Hi I lost my spray head for my Bunn coffee maker - is there a hack to still be able to make coffee while I wait for the new part?


Depends on your model. The smaller pour over units are easy as you prep your funnel with coffee as normal and get a full pot of hot water (just brew the water through the brew head and funnel to fill the pot.) If you have another pot or carafe, air pump pot. Then hold the coffee filled funnel (with coffee filter) over the empty pot and slowly pour the hot water over the coffee grounds. Go slow as you don't want to burn your other hand nor get grounds into the pot if you over fill the filter.
* If this is a 1-1/2 gallon brewer then the missing shower head won't mater that much as most of the 'flavor' is extracted in the first 1/2 gallon with the rest just filling the urn. If you do find the coffee to be weak then perform 3 separate 1/2 gallon brews to allow the grounds to fully soak and extract. Again, you can still do it manually as described above but it does get messy and very slow. (I've done this just to get something out to the customer. Well until I could get the repaired brewer up and running.)
* Most of the Bunn decanter brewers use a quarter size screw on spray head. No real substitute, though you could try a stiff sheet of aluminum foil to cover the coffee grounds in the funnel and poke holes into it. Though more than likely one of the waiters will dump it on the next brew.
* On one occasion (during lunch rush) I had to wait on a repaired urn to heat up but the waiter's needed coffee now! I took a pour over small brewer and made a pot with 1/2 gallon strength coffee and poured it into a larger urn then brewed more 'partial' batches till it was full. Hey, got to do what needed to get it out.
* You should always check with your coffee vendor as spray heads are very common parts and available at your local restaurant supply. There are other brands that use the same parts too like bloomfield. Ask around as this is a fairly cheap part.

Have a bunn vps series pour over that won't brew


VPS are pour over brewers. Like the 12 cup brewers you find at home, they need to be filled with 12 cups of water (a full pot), heated and then peculated over the coffee grounds and collected in a decanter.
BUT there is one main difference! The VPR and similar COMMERCIAL coffee machines are quick brewers. They usually have a pre-heated pot of water stored inside the machine.
* VPR's and similar machines REQUIRE a pre-fill and heating period prior to brewing. This means it's sitting on a level table and filled with water until water sprays from the brew head. At this point the unit is plugged in and the heater is turned on. Brewer will pre-heat the water (there may be some water discharge from brew head as the water expands). Ready light will come on in about 15 mins.
* To Brew; Place coffee grounds in filter, place in funnel and brew head, clean empty decanter under funnel, slowly pour one full decanter of water (cold or hot) into brew tray. Do not overflow tray. Allow water level to sink before adding more water. Only fill with one pot as an equal amount will come out the brew head and funnel.
* You can test the VPR by following the Pre-fill instructions I've listed earlier. If the brewer heats up and does not continuously boil (shorted condition) then try a brew. If it works then your okay. Otherwise the unit will need service for a blown high limit or bad heater element.
* Call your coffee vendor anyway. Many coffee vendors will service your brewer of even replace it as long as you buy coffee from them. Ask around.

Bunn CW Coffee Brewer not brewing enough coffee - amount is half


Have you cleaned lately, put in an empty filter and fill with cold water with a tablespoon of white/clear vinegar. Run the brew cycle, empty pot and while still worm fill with cold water again with out vinegar. Than check filter to see how much hard water chunks are in the filter. Repeat with and without vinegar tell filter is clean. One question though is there a lot of steam coming out of the top during the brewing cycle if so inside there is a tube that may be cracked, broken or came loose, have to look inside. requires opening or disassembling unit to check. REMEMBER when taking apart UNPLUG unit first.

Sounds like the switch is stuck in the operate position. Therefor once the machine hits temperature it just brews. Your local Bunn distributor should be able to recommend an engineer to replace the switch or supply the correct t,hope of switch if your confident enought Tom replace it yourself.

The brewer is on a gravity feed system, after the initial fill, whatever you put in is what comes out. as for the start button check the water connection on the back, there might be a problem with the solenoid.

Programing for best cup


when feeling upper crusty, I like the pre-soak method, using my good old bunn machine a small blast of 195 degree water to steep for 45 seconds to a minute, followed by the remaining 195 degree water to brew my desired quantity. but I seldom wish to muck about when I want some coffee, so use my good old bunn old school brewer the way it was originally designed,... add grounds, pour water, enjoy coffee!

My cw series is a plumbed-in unit. Water flows continuously from the spray head. I think that either (1) the water level sensor is bad (2) the shut off valve is stuck open. Ideas? Can the water level...


The CW series brewers do not have level probes they run strictly on a timer and a solenoid to control the water flow. So, that said, the problem could be the solenoid. If the brewer constantly drips/runs even when the front "ON/OFF" switch is off then it is the solenoid. If the brewing stops with switch off then it is the timer. The timer is located in the panel behind the filter basket on the front of the machine (6 screws) If the brewer has a manual timer set it to about 2 minutes, a good starting point for a pot of water (1/2 gallon). If it stops brewing then you need to fine tune the timer to give you right amount of water for your brewing method. If it doesn't stop... then you will need a new timer. If your brewer does NOT have a "dial/manual" timer follow the instructions on the backside of the panel to "reset" the brew level. If it does not reset you will need a new control board. Hope this helps.
