How to Identify and Fix Common Vacuum Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced Vacuum Technicians :

Take a suction cup and firmly press it against a wall. The volume inside the cup decreases as air flows out of the cup, creating a vacuum. This reduces the inside pressure and causes the cup to stick to the wall.
A vacuum coffee maker operates as a siphon, where heating and cooling the lower vessel changes the vapor pressure of water in the lower, first pushing the water up into the upper vessel, then allowing the water to fall back down into the lower vessel.
We recommend a 1:16 ratio of coffee to water. With this brew method, we advise using 9 grams of coffee for every 6 ounces of water. Grind coffee on a medium grind.
Clean the Needles

If after descaling, your problem with the Keurig not brewing a full cup is still happening, it may be the needles that are the problem. Believe it or not, debris, like foil from the K-Cup, can get lodged in the needles that pierce the cup, disrupting flow.

The most likely reason for a Keurig not pumping water is water scaling, debris that builds up and interferes with the Keurig water pump. There are a number of ways to resolve this problem. The simplest is to take out the Keurig water reservoir, empty it out, and refill it about a third of the way.
When it does cool down, the pressure will then drop to less than atmospheric pressure, so you`ll have a partial vacuum. Probably the easiest way to create a vacuum at home is with a suction cup. If you press a suction cup flat against a wall and pull back, the inside of the cup will contain a vacuum.
The change of pressure and force of gravity then vacuums the coffee downwards through the filter to the bottom flask. This method produces a superior taste that avoids boiling the coffee, which is why syphon coffee makers are widely celebrated for brewing some of the best, purest coffee.
Putting your coffee beans in a vacuum-sealed bag helps you keep them fresh for a year. The one-way valve is a must because it lets CO2 out and stops air from getting inside the plastic bag, which could make your coffee beans stale.
Vacuum packing ensures that coffee is protected from the effects of oxygen, moisture and other environmental factors.
The standard ratio for brewing coffee is 1-2 tablespoons of ground coffee per 6 ounces of water – 1 tablespoon for lighter coffee and 2 for stronger coffee. That 6-ounce measure is equivalent to one “cup” in a standard coffeemaker, but keep in mind that the standard mug size is closer to 12 ounces or larger.
A level coffee scoop holds approximately 2 tablespoons of coffee. So, for a strong cup of coffee, you want one scoop per cup. For a weaker cup, you might go with 1 scoop per 2 cups of coffee or 1.5 scoops for 2 cups.
If your Keurig suddenly stops brewing full cups of coffee, you may have a clog. This is a common problem that is fixable after washing all the removable parts with dish soap and hot water. Most clogs caused by coffee grounds are easy to break up with nothing more than a paperclip and a plastic straw.
What to do if your Keurig® brewer says to add water but it is full. Make sure that the water reservoir is seated properly in the base. Remove, empty, and thoroughly clean the reservoir. Then fill with fresh water and place it back in the base.
In many cases, the Keurig watery coffee problem is due to a clogged needle, mineral or coffee bean oil buildups, or improper usage with reusable filters. Cleaning and descaling your Keurig is a great start to fixing your watery coffee.
Ultimately, a perfect vacuum isn`t possible because quantum theory dictates that energy fluctuations known as `virtual particles` are constantly popping in and out of existence, even in `empty` space. Read more: How can something explode in the vacuum of space?
noun. an enclosed space from which part of the air or another gas has been removed.
Gravity and friction are the two main forces that make vacuum suction work. While gravity pulls molecules in the air toward the earth, creating an atmospheric pressure, the suction cup and vacuum pump cause a pressure difference, attaching both surfaces.
It seems bizarre, but it is possible to make vacuum with compressed air. Vacuum eductors, sometimes called ejectors, or venturi use a flow of compress through a specialized nozzle to create vacuum without a mechanical vacuum pump. The process in its simplest form uses no moving parts, so it is very reliable.
To preserve your beans` fresh roasted flavor as long as possible, store them in an opaque, air-tight container at room temperature. Coffee beans can be beautiful, but avoid clear canisters which will allow light to compromise the taste of your coffee. Keep your beans in a dark and cool location.
Vacuum Siphon Coffee is smooth, full-bodied, crisp, clean and rich in flavor coffee thanks to the sophisticated coffee making method. Types of coffee brewing: Taste of coffee differs with coffee brewing methods.
The French Press method, invented in 1929, is widely considered as the best and easiest method for brewing superior and consistent coffee. It extracts, arguably, more superior flavours than any other method.
The answer is no, coffee does not actually go bad, and a “bad” cup of coffee won`t make you sick. But, if coffee grounds or beans get wet, then yes, they can`t be reused and need to be tossed. Coffee is a dry, packaged food and like most dry goods, there is no firm expiration date to keep in mind.
In short, roasted coffee beans can last for up to a year in a vacuum-sealed bag or air-tight container. Making a cup of coffee is fairly easy, but making the perfect cup requires some extra care.
Storing your vacuum sealed coffee beans in the freezer will keep moisture away from the coffee, decrease air movement, limit temperature fluctuations, avoid the dreaded exposure to light, and keep your coffee from losing its vacuum seal.

Our Bissell Cleanview II 3576M does a great job except that the filter cup below the dirt cup gets full very fast and the dirt cup barely has anything in it. To clean the whole house, I have to empty the dirt cup and clean the filter several times. It didn’t use to work this way. It seems like something is missing, a gasket or seal maybe? I don’t think dirt, hair and debris should be going straight to the lower cup and bypassing the upper. I looked at the user guide but can’t see why it’s happen

I have a kitchenaid artisan coffee machine which is 15 months old just out of warranty. when you start to make an esspresso coffee the machine runs but no water is being pumped through the coffee to the cup you can hear the machine working but no coffee.
Thanks Lloyd
ANSWER : Hello lloyd….. There are a few possible causes of this problem. The first is using coffee which is too fine a grind. The second is a machine which needs to be thoroughly cleaned. Most can fix those two areas themselves. The other causes have to do with the amount of pressure the machine is producing. If, for instance the boiler safety valve opens too soon, the pump will not get to the necessary pressure of 7 to 9 bars.
.That said, begin by cleaning it thoroughly as per the manual. IF you do not have a manual, here is the link to all kitchenaid manuals
.Thanks for choosing Fixya!

    The Funnel can be removed from the K-Cup Holder by pulling on it .until it snaps off. The Funnel is dishwasher safe. To replace it just .snap it back onto the K-Cup Holder.
  4. .

  5. Clean the exit needle.
    The exit needle is located on the inside bottom of the K-Cup Holder.. If coffee grounds or cocoa mix gets clogged in the exit needle, it can .be cleaned using a paper clip or similar tool. Remove the Funnel from .the K-Cup Holder, insert the paper clip into the tube and move it around. to loosen the clog and remove any debris.

Went to turn it on after not using for several weeks and it states not ready to brew like usual but after about four minutes it just turns off. Wont let us brew a cup or access the menu even to choose size of cup or anything. It sounds like it’s sucking up water to make cup and pokes hole in the coffee but nothing more than that. It is almost brand new
ANSWER : You have posted the fault in the wrong column with no instruction of the make/model.
.Assuming it to be new , Is it passed the warranty period before we take a look ,?
.Just lave it on for sometime and see if there is any change. perhaps the controller is thinking different with some errors , so lets try that it will stabilise with the stteady power inside.
.check this out and comment.

Please tell me how to get it apart – after 2 years it is really filthy!!

Thank you,

ANSWER : Remove all the screws, pry clips off that hold on the extensions, than fan will pull apart. The clips must be pried off. They will not break. Then remove screws holding in the fans and remove them as well. Fairly simple process.
