My Bunn Coffee maker has one solid stream of water running from the nozzle. It goes straight down through the filter. The coffee is weak. Isn't the nozzle suppose to spay? I thought about using a little LCR on the it - but everything else works okay, and I don't know the effects of the cleaner on the internal gaskets, etc. Right now, I'm doing the French Press thing by pouring a 1/2 of hot water in the basket after brewing and making a "malt" to add to the freshly brewed coffee...which is a pain in the ****...but it makes the coffee the right strength for number of scoops used.

clean with CLR and then water rinse....use DRIP fine grind
1 tablespoon per cup..........remember strength is the coffee and the amount of water.

This unit has a sprayer head that might be the problem. Start with the water. Filtered water is best after all, coffee is mostly water. As the water is heated to the optimum degrees it must spend the right amount of time going thru the grounds. The grounds have also an optimal size. We opted to have our own coffee grinder so we can select the right size for the righ taste for our needs. Now, do not go buy bottled water. That is WAY too expensive. Opt for a water filter. There are quite a few. If the water and the grounds are the right combo but still weak coffee call the customer service at Bunn and see what they have to say. Some customers have reported issues to them and a solution might be at hand, or a new sprayer might be needed. Good luck.

Hello. the problem is the little sprayer that sprays water into the coffee grounds. They get clogged with coffee oil and coffee grounds. Unplug the machine, tip it upside down in the sink so the water doesn't go everywhere and use a straight pin to clean out the little holes of the spray nozzle. That nozzle should unscrew, which would make it easier to clean. When you are looking at the nozzle, unscrew it by turning it counterclockwise. Joe

The little sprinkler in the grounds basket fell off and you probably accidentally threw it out. It splits the hot water stream into three streams. I just emailed bunn and they sent me one for free.

This is usually caused by a missing sprayhead above your filter basket. take out the filter basket, and see if there is a sprayhead up there, or if there is just a little round pipe that the prayhead screws on to. If it is missing, you can contact your local Bunn dealer, or phone bunn directly, and they will take care of you. You can get a list of repair centers in your area at www.bunn.com

I work 4 BUNN and we have a flow restrictor sprayhead that might help. If you send me your address we can send one out to you.

Some people also try adding fresh grounds to brewed grounds, resulting in an overflow. A restricter valve can be used, but a better solution is to simply pour in half the water at a time. This is what people who buy non Bunn filters do to stop overfills.

Hello. Have you checked your temperature of the water? If it is not hot enough, 185 to 195, it will not extract the coffee properly, causing a weak brew. Putting the spring through the spray tube does not necessarily clean the whole water brew system, and you could still have a flow problem to the sprayhead. You can check it, just pour in water, no coffee or filter, the funnel in place, a pan or something to catch the water, and while it is brewing, with a flashlight, pull down, or forward enough on the funnel to look at the spray head, there should be 5 or 6 streams of water coming out of the sprayer. If it is dribbling out, and down the sprayer, or not a decent flow from the holes, you still have a blockage somewhere. You can go here to get a parts manual for your unit, to see how things come apart etc..

You may just need additional cleaning, if it is bad, it may require chemicals.

Hope that helped, and thank you.

Basing on personal experience (you can find more on Google probably), solutions are:

On percolated (filter) coffee machines:

Check water temp, if water temp is insufficient , most common is scale heating element , faulty element, faulty thermostat.
Check if water is dripping right at the center of the filter, if it is dripping on one side because the orifice is clogged, that can result in weak coffee.
Coffee blend not well distributed on filter basket.

On Espresso machines:

Check water temp, same as filter coffee machines (thermostat element, scale on heating chamber).
Ensure that coffee is filled correctly in the filter cup (fill at level), and well pressed.
Ensure that the coffee mixture that you are using is not too coarse, buy the apposite one for espresso.
Ensure that you are not leaving the machine brewing for a time that is too long, and Italian coffee cup is very small, approximately one regular shot.

On the hob moka pots (espresso, Moka and Bialetti type):

This are the trickiest ones, you need art and practice to get a good espresso with a Moka, but when you learn, the result is better than what you may get with an home electrical espresso maker.
The frame on the hob must be not too strong, and the mixture coarse but well pressed, with water at level tag, or you will get a weak coffee.
On Mokas a good strategy is keeping hob at minimum, and turning up the flame at top when coffee starts coming out.

French and turkish cafetieres:

Ensure that you put enough coffee, water hot enough, and that you left the infusion enough time to get a strong coffee.

Note: insufficient pressure and clogged lines on electric machines never give you a weak coffee, exactly the opposite.
Not pressed mixture always gives weak coffee, but too much pressed mixture may give you coffee with bad taste.

After reviewing troubleshooting diagrams, I really couldn't find a solution to your problem.

The only thing I can suggest is to use 2 oz per pot of coffee grounds. Your 5 or 6 scoops assuming they are one ounce each is way more than enough.

Look under where your basket goes. Most bunn coffee maker has a flavor guard on the downspout. this down spout actually helps distributes the water over the whole basket of coffee grounds. Most of the time I see these missing, and when they are gone, they are gone.

Use less water for the amount of coffee you are using first. Sadly when there is not enough water, the coffee tastes bitter. Too much water tastes weak. Hot water extracts certain elements out of the beans even after grinding.

Always use a fresh paperfilter designed for your coffee maker.
If this pot is not work correctly still, I will suggest seeing your appliance repair technician.
