I don't know what the flow restrictor looks like, but I know what a spray head looks like.
My new Bunn BTX-B brewed weak coffee also. I was wasting coffee to get it stronger. I decided to inspect the spray head. What The hey! What Spray Head? The coffee maker didn't even have one. I guess the assembler forgot to put it on. Yet it made it thru quality control. No wonder it was making weak coffee, and I was wasting coffee to try get it stronger.
Is your making weak coffee? CHECK YOUR SPRAY HEAD. Make sure the coffee maker has one on it.

    Mine is very weak as well.

    I received that "flow restrictor" and I still need to add too much coffee for flavor. Wasting coffee, here, because the grounds can't steep in this one. When buying this machine, I was under the impression that Bunn machines were made by connoisseurs. This one was obviously not tested before marketing, or Bunn engineers aren't coffee drinkers. Thanks for the "restrictor."

    I sent for the flow restrictor and same thing, weak coffee, I tried 4 or 5 different brands, I even bought beans and ground them myself, and even when I added more than half a cup of coffee grounds to brew it was still weak. I resorted back to my $8.00 5 cup Mainstay coffee maker at Walmart that I had bought for when traveling and it brews a 100% better cup of coffee than my $100.00 Bunn. My Bunn is in the closet and after spending 100.00 on a Bunn, I have an $8.00 coffee maker on my quartz counter, it looks so cheap but makes a good cup of coffee.

Coffee brewing comes out in a fast steady stream when brewing, coffee doesn't brew properly and comes out weak. taste like unbrewed.

If it comes out in a steady "stream" it sounds like the sprayhead is missing. The sprayhead disperses the water out and evenly over the grounds.
If the sprayhead IS in place then it could be a temperature problem. If the temperature is not hot enough the coffee will not brew correctly.

I work for BUNN. It sounds like your sprayhead is missing because it should definitely be spraying versus flowing. We will send you out a free sprayhead - please call our customer service department at 1800 - 352-2866 with your model and will send it right out to you.

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.

My bunn thermofresh coffee pot will no longer keep the coffee hot. I always put hot water in the pot for up to five minutes to heat it up. This still doesnt help.

Is the coffee coming out hot enough? If you measure the coffee as it comes into the carafe, it should register at 175-185 degrees. If it doesn't, then it is a problem with the machine and needs to be replaced. If it is that temperature, then the carafe needs to be replaced. Please contact customer service with the model and date code located on the bottom of the machine. If the machine is 3 years or less it can be replaced at no cost. If over 3 years, it can be replaced at a reduced cost.

Weak coffee

It sounds like you may have lost the sprayhead. It is under the brew basket (above the place where you put the basket with the filter and the coffee). Sometimes they get loose and you don't realize it and it can fall in the grounds and get tossed out after brewing.

Coffee is weak and watery

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.
