Coffee grounds in the coffee pot. It appears water does not flow into pot quickly enough, so filter basket overfills and causes grounds to go up and over the filter, then flow into pot. Also heat plate does not keep coffee hot enough. Have checked the spring in filter basket, it appears to work fine. Checked the lid on coffee pot, it seems to be fine too.

There are a few possible reasons why the coffee dispenser bar on your Hamilton Beach

1. Check the water level in the reservoir. Make sure that there is enough water in the reservoir to brew a full pot of coffee. If the water level is too low, the coffee dispenser bar may not work properly.
2. Clean the coffee dispenser bar. Over time, coffee grounds and other debris can accumulate on the coffee dispenser bar, clogging it and preventing the coffee from flowing properly. To clean the bar, run a solution of equal parts water and vinegar through the coffeepot and then rinse it thoroughly.
3. Check the filter basket. Make sure that the filter basket is properly seated in the coffeepot and that it is not clogged with grounds. If the basket is not properly seated or is clogged, it may prevent the coffee from flowing through the dispenser bar.
4. Check the gasket. The gasket is a rubber seal that helps to create a tight seal between the carafe and the coffeepot. If the gasket is damaged or worn, it may cause a leak and prevent the coffee from flowing through the dispenser bar.

If none of these troubleshooting steps resolve the issue, it is possible that there is a problem with the coffeepot itself. In this case, you may need to have it repaired or replaced.

Good morning Kenneth.

There are a couple directions you could take to diagnose this.
Since the change happened overnight, or quickly in any case, this tends to suggest clogging or contamination that happened recently.
My suggestions:

1. Try running a batch of coffee with no grounds in at all. Fill up the water, run it on 'pre-ground' mode, and let the hot water run into the tank. Is the water clear in appearance as expected? Does the water run into the pot in about the time you'd expect? Does it flow readily from the filter outlet into the pot, or come in dribbles and spurts? And... if you taste the warm water, does it taste like nice neutral water, or is there an overall taste?
2. If any of the above is true, then your water path can me mucked up. A few possibilities here would be :
   1. There is usually a water filter in the unit, which will get gunked up with water filtrate, or just algae over time. You'll need to look at your manual for your particular model to find how to access it. Changing the filter can make a big difference in both taste and in how reliably water flows from the reservoir.
   2. The filter cone is gunked up. Usually you can remove the entire filter cone assembly for cleaning. There is pretty much always a spring-loaded push valve on the bottom that will not allow coffee to flow out the bottom unless the pot is in place. This can get majorly gunked up with old coffee grounds that overflowed at some point or another. Make sure the valve is free of debris, along with the surrounding area.
3. if the water path is ok, then 'weak' coffee translates into 'the water and the grounds are not interacting enough'. that can come from a couple directions:
   1. Not enough coffee, or stale coffee. I'm discounting that since you said you'd already tried both pre-ground and auto, and i assume you used the same amount of coffee grounds.
   2. Water is not hot enough to extract coffee essence from the grounds. If the system is pumping the water over the grounds, but it's cold, then if you are on morning auto-mode, it's possible the morning timer is running tepid water, and then heating it with the pot heater.
   3. Water is hot, but not in contact with the grounds long enough to extract much. This could either be that the system is flowing really fast - whether high water flow would mean fast pass-through will depend on the filter specifics, or that it's by=passing the filter. If there is an overflow catch that will still direct the coffee to the pot is it misses, then you may be either flooding and catching, or the filter might be mis-seated, so that some significant amount of the water can just flow past it. Your description reminds me of some times that the paper filter in my system has folded over, so that the water is dripping against the outside of the paper filter and then running down to the bottom of the filter holder. Bleccch.
   Hoping this is helpful!
   
   Good Luck

Steven, I think it`s not the filter or the coffee just that more water is flowing into the basket then it can process. I would try lesser quantity of water first to see if it overflows. Try first with filter only and then with coffee. And before you do all that, your machine should be under warranty and may be returnable to the store. Do that and save the trouble of fixing it.

The Manual for your coffee maker can be found here:

http://www.cuisinart.ca/pdf/ibs/en/DGB-600BCC_en.pdf

'Leaks' are usually caused by overfilling either the water reservoir or the coffee basket or by coffee grounds interfering with a seal.

Make sure you perform a complete cleaning on your coffee maker making sure any contact points which need to seal are free of coffee grounds.

Instructions for removing the grinder and filter baskets are contained within your manual.

You should be able to pick up a replacement/new pot at your nearest Restaurant Supply store. Make sure you get a 64 oz./ 1/2 gallon pot.
Before plugging in your brewer, unscrew the sprayhead located just above where the filter basket sits and replace the basket, pour 3 pots of cold water through the opening on the top if the brewer is empty. This brewer has a reservoir that holds about 2 1/2 pots of water at brewing temperature when heated. Make sure you put an empty pot under the filter basket after pouring in the water. Water will flow from the brew basket when the reservoir has reached its capacity. Once water flows you can then plug in and energize your brewer and replace the sprayhead. It will take about 15 to 20 minutes for the brewer to reach brew temp, you will hear the heating stop. Put an empty filter and a dose of coffee (I recommend starting with a heaping measuring cup of drip ground coffee) into the filter basket, lightly shake it level, replace the basket and pour through 1 full pot of COLD water in the top. For best results pour the brewed coffee into a pre-heated thermal server if you plan on holding the coffee for more than 10 minutes or so.
Enjoy!

These tanks can't actually be overfilled since all water poured in displaces the exact same amount of water coming out the spout. So, whatever amount of water you pour in, will be the same amount of water that flows to your pot minus the amount absorbed by the coffee grounds and filter.

Your problems sounds like an undersized (Non Bunn) filter, or clogged brew basket. To verify this, try pouring in only half the water for your brew cycle and wait for it to finish dripping, then pour in the rest. If no overflow has occurred, you simply have the wrong type of filter. If overflow begins again, you have a clogged brew basket, since no Bunn can flow too fast for the brew basket to keep up with it.

This is because Bunn filters are manufactured differently than generic store bought paper filters. They will flow faster, brew cleaner and stand up better than normal generic filters.
Remember, Bunn makes their OWN filters for good reason.
They made the first, best paper filters for drip coffee pots, and all others are just generic dioxin gas producing paper.

There is a lever in the back of the carafe area that pivots and controls a spring loaged valve on the bottom of the removeable filter basket. This lever breaks easily. Pull the filter basket out and you can see the lever hanging down into the carafe "bay". (assuming it's not broken off entirely).

When you pull the pot out during brewing, the lever swings forward and allows the valve on the bottom of the filter basket to close. This shuts off the flow of coffee to avoid drips. The plastic lever is held in place underneath the valve by two round tab "ears". One of these ears can break off, causing the level to hang at an angle. This means the filter valve never completely opens, even if the pot is pushed in all the way. During brewing, the filter basket can't drain into the pot fast enough and overflows.

I fixed mine by going ahead and removing the damaged lever and then wedging the valve open. The spring loaded valve has a little drip "Spout" which hangs underneath the filter basket that directs the coffee into the pot. You can push in on the back of the drip spout and wedge something into the two slots at the back to hold the valve open. This let the coffee flow freely during brewing.

Coffee overflowing onto the counter is a common complaint found in response to many automatic drip coffee makers. The following are potential solutions that can be used to rule out "operator error" vs. a defect or malfunction:

1. Do not "pack" or otherwise overfill the cone/basket with grinds.
2. Ensure you are using the correct grind for an automatic drip coffee maker, neither too fine nor too course. (See instruction manual.)
3. Do not overfill with water. Use the carafe to pour water into the reservoir. This is because a "cup" in coffee terms is defined as 6 oz, not 8 oz. Note: Some coffee makers define as little as 5 oz as a cup.
4. Make sure the filter cone/basket clicks into place and that the carafe is centered and pushed all the way in.
5. Try a permanent filter rather than a paper filter or vice versa.
6. Only use the correct permanent or paper filter (see manual).
7. Verify that the Pause 'n Serve button isn't sticking. If it is activated too long the brew will escape over the top of the cone/basket. This may be more apt to happen if the alignment of the carafe and the basket is incorrect.
8. Clean your machine with vinegar or as instructed by your user manual at least three times per year, more if your water supply is hard. A properly cleaned machine is less likely to suffer a burned out heating element, to take too long to brew, to produce "off" tasting coffee, or to clog and overrun the filter basket as the water runs through the grinds.
9. Ensure that the coffee machine is sitting level on the counter.

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.

Iam useing the right filter.
