Sounds like the solenoid is the problem.

Have you tried running vinigar or a cleaner throught with the water or running a wire up it .Sometimes they plug up withlime and will not allow the water to run.Be sure and rinse it well after the cleanser so everything runs clear and you may have to do this two or three times, depending on how pluged it is.

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.

You have to get to it from the front panel. Remove the 6 screws for access.

Descale the tank and replace the water filter on the coffee brewer inlet line.

You actually don't have to turn off the machine to set the volume. They just want you to be careful.

Hello. If this is the hot water faucet, on the front of the unit, there is a rubber seat that keeps it sealed. Usually it gets a piece of debris, or scale in it with use, or the rubber seat gets worn out and needs replacement. To check, turn off your water, unplug the unit, and drain all the water out of the faucet until it stops, then tilt the unit forward slightly just to get a little more. Now you should be able to unscrew/disassemble the faucet, and pull it out to look at the seat cup, and the faucet interior. If there is scale or debris on the cup, and the faucet interior, it will need to be cleaned, and it may actually require chemicals for scale, if bad enough. If the rubber seat cup is torn, it will need a new one. You can get a new seat at a parts supplier for commercial units in your local area, look in the phone book under "restaurant equipment repair" or go online, plenty of them have a web site. If it is NOT your faucet dripping, we can go from there.

Hope that helps, and thank you.

There is an inline thermal fuse on the right side of the element, check to see, if it has resistance, if not replace.

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 .

test element for failure

Bunn Coffee... | Answered on Oct 06, 2019

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.
