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

Hi there! I'm sorry to hear that your Tchibo coffee maker is not brewing the large size coffee properly. Here are a few suggestions that might help:

1. Check the water level in the water tank. If the water level is too low, the machine may not be able to brew the large size coffee.
2. Make sure that the coffee filter is properly inserted into the filter holder. If the filter is not inserted properly, the machine may not be able to brew the large size coffee.
3. Clean the coffee maker. The coffee maker may be clogged, which can prevent it from brewing the large size coffee properly. You can clean the coffee maker with a mild detergent and water.
4. Descale the coffee maker. If the coffee maker is not descaled regularly, it can build up calcium deposits, which can prevent it from brewing the large size coffee properly. You can descale the coffee maker with a descaling solution.

If you have checked all of these things and the large size coffee is still not brewing properly, then you may need to contact Tchibo customer support for further assistance.
Here are some additional tips that might help:

• Use fresh, cold water. Stale or warm water can affect the taste of the coffee.
• Use a good quality coffee. Cheap coffee beans can make the coffee taste bitter.
• Grind the coffee beans to a medium-coarse grind. A too fine grind can make the coffee taste bitter, while a too coarse grind can make the coffee taste weak.
• Clean the coffee maker regularly. A dirty coffee maker can make the coffee taste bitter.

I hope these suggestions help!

If there is a thin water line in your coffee maker, then it can get clogged or could have mineral build up. Keurig coffee maker, you are going to want to descale it every 6 months. Calcium can build up.You need to run a large cup of white vinegar through coffee maker lines. When you run vinegar through there, the coffee will taste nasty, so I would run water in there several times, after the vinegar finishes. Run through until does not taste nasty anymore. Yeah, I do this with my coffee pot 3 times a year. You judge how often you should.
Good luck.

First set the clock on the brewer with the unit plugged in. Press and hold the Hour and Minute buttons until the current time is set. Next press the Delay Brew button while using the Hour and Minute buttons to reach the time you want the coffee to begin brewing.

Set up the coffee maker with ground coffee or beans and sufficient water in the reservoir then follow the directions below.

For brewing with fresh ground beans, press and hold the Delay Brew button until it flashes then press Select once. The Grind and Brew light should come on and the Delay Brew light should become steady.

For ground coffee, press and hold the Delay Brew button and then press Select twice. The Brew Only light and the Delay Brew light should both be on and steady.

Most coffee brewing sites say to use 2 tablespoons of ground coffee for 6 ounces of water. Since the grind can vary, they also say to use 10 grams of coffee per 6 ounces of water. Going by weight ensures the proper ratio.

If you're making coffee for yourself, of course, the proper ratio is whatever gives you the taste you most enjoy. Start with the 10g-to-6 ounces ratio and adjust as desired. Not all roasts and beans brew exactly alike.

Don't forget to keep your coffee maker clean, and use filtered water. This can have a great effect on the coffee's taste.

Run a solution of 1/2 cup white vinegar and 1 cup water through the coffee maker and clean it out.
Then brew a good cup of coffee.

Unless the brew level comes up short while brewing.

Doesn't sound like a descaler issue. I am having problems with mine and noticed that water is flowing back into the reservoir when it is pouring into the coffee cup. I think there is a valve that is not closing properly.

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.

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.


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.

Yep, it's the one inherent flaw in the single serve machines - someone else decides what 'the perfect cup of coffee' tastes like.  Quite presumptuous, actually.  
Solution I found to be acceptable:  Buy only the extra bold flavors (there's about 5 or 6 varieties) and brew using the small cup size button.  Yes, you only fill your mug about 3/4 of the way, but at least you get a decent cup of coffee.  
The ONLY flavor I found to be strong enough when brewing with the large cup control button is DOUBLE BLACK DIAMOND...the rest is crap.
