How to restore flow to a slow machine

We have a EN380m which has slowed to the point where the coffee comes out a drips rather than a constant flow. we have descaled the machine twice even though the descale light never came on, any ideas other than buy a new one?

SOURCE: I have a Delongli EC330S and has reduced it coffee

I have the same problem with the EC330S model.
I can restore the flow by removing the parts where the water comes out. First a metal plate with small holes held by one central screw. Then there is a piece of metal in the middle with a slot in it which can also be screwed out to release a spring with a little plastic domed piece on the end. It seems to be this plastic part which sticks when the flow is reduced.
However I am also looking for solutions because checking these parts only fixes the problem temporarily.

SOURCE: Delonghi coffee machine making an aweful noise,

Hi. Husband asks: When you first turn the machine on at the power point, does it make a motor sound and then stop, or is the awful noise apparent at that time.

If the awful noise starts as soon as you turn it on, then most likely there is a motor problem which will need to be seen by a Service Center.

Keeps dripping after coffee is finished

There could be a small clog in the line where it slows the flow & then remaining water continues to slowly drip after brewing is done. Try running vinegar through it.

I have an older model cuisinart 12 cup coffee maker. This am the water will only slow drip through the filter. There is lots of gurgling but not much coffee. Can u help me figure out what's wrong?

Calcium buildup. Follow your coffee maker's manual cleaning procedures to dissolve the hardness buildup.

If you can't find your manual, try mixing 1-2 cup of white vinegar in an 8-oz to 12-oz pot of water and pour it into the water receptor. Run the coffee maker until about 1/2 the water has passed through the machine then turn it off and let it stand for awhile (say an hour). Then turn it back on and let it finish. This should dissolve the hardness buildup in the machine and restore the flow. If not repeat. If you use a paper filter during the process, you should capture all sorts of hardness particles.

After it's flowing good again, run with one or two pots of water to rinse.

Why is there coffee on the burner, after coffee brews?

The flow control valve on the strainer basket (where the coffee pours into the pot) is a less-than-stellar device. While adequate to prevent a flow of coffee when you pull out the pot, it will still retain a few drops which slowly drip onto the warming plate while you are pouring a cup. It may even allow a slow, continuous drip, especially if coffee grounds find their way past the filter.

Keep a damp cloth or paper towel near the coffeemaker while it is on. Just before returning the pot to the plate, give it a quick wipe.

Water does not go through the cup

The drip spout may be clogged. Easy fix, just poke through it with something like an ice pick or even a paper clip. Also, you may be using too much coffee grinds which could slow down or stop completely the flow of water.

My Bunn has a slow drip. Model GRX-B. Have cleaned the disc sprayer and pushed the spring up in the hole. What else can I do? It used to drip a lot faster.

How old is the machine? If you have cleaned it and delimed the machine and it still is dripping slow, the machine may need to be replaced. Please call service at 800-352-2866 with the model and date code.

I have a Delongli EC330S and has reduced it coffee flow to a very slow drip, pump sounds ok, can't see any pipe blockages,I need help

I think I have solved this problem quite simply by buying a new pack of Expresso coffee, it seems that I must have ground the coffee beans I had too finely if that is possible, But it does seem to be working ok now

Can I adjust the water flow for finely ground coffee?

You probably have coffee ground for a drip coffee pot, not an automatic drip coffee maker. With a drip coffee pot, you put the coffee in and add the hot water on top of that. You might want to try a coffee press. They are fantastic for the finer grinds of coffee. Some Mexican coffees are ground almost as fine as flour and a press works great. You can get a press for about $12 & up.

Very slow output to fill cup

You will need to Descale the Machines. Most likely calcium bulidup inside machine.
