Increasing water flow rate

How do I adjust the machine to increase the water flow rate to the coffee basket?

    My problem is similar. I have a La San Marco 2 group head manual. My water flows at about 250ml in 7 seconds. Far too fast meaning that I am compensating to get my 60ml in 25 second shot by grinding very fine. The water pressure is set at 9 bars. How to I lower the water flow rate?

Back-flush the machine regularly and check your water hookup and make sure you to not have a small diameter water line. Other than that it is controlled by the water pump I believe. If the solenoid (the silver thing attached to the pump) used to start the pump is old it could slow down the pump start cycle.

Nuova simonelli appia2 , steam fine hot water fine but when I make a coffee , it be a cold coffee ?

if you remove the drain tray, there is another plastic cover with screws. remove that too. inside on the right side you will see a black box with a yellow round cap. peel the cap off then you can see a screw. there is also a label that describe the direction of rotation. adjust it there. this is to adjust the pressure of steam. as your machine is increasing steam pressure, it also increases the water temp.

Water will get hot but not flow to the mixing basket

Most likely your system needs to be de-limed. All water has a certain amount of dissolved minerals in it and when heated those minerals will precipitate out into a white, crusty material. Often this material will clog up the works of your coffee maker.
In order to remove the deposits, you have to increase the acidity of the liquid within the coffee maker. The easiest way to do this is to drain the water and then fill the maker with about 18 ounces of white vinegar that you can buy from your local supermarket.
It may take some time before the lime deposits dissolve and you may even have to use a wire probe to carefully remove any blockage of any of the holes that the water has to flow-through to get through the system.
After you've got the lime removed and the unit is working properly, run some clean water through the system and clean any external parts to make sure you don't get vinegar flavored coffee.

Filter basket overflows after cleaning Bunn VPR Coffee Maker

Some people also try adding fresh grounds to brewed grounds, resulting in an overflow. A restricter valve can be used, but a better solution is to simply pour in half the water at a time. This is what people who buy non Bunn filters do to stop overfills.

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.

Saeco Primea Touch Plus flow problem

In the bean hopoer there is a little screw. Remove this screw and the cover and you will see an adjustment alan key. You need to push down and rotate the adjuster counter clockwise to make it finer and clockwise to make it bigger. Make sure you only rotate the grinder a little at a time, 1/4 turns at a time recommended. Make 2 cups then readjust if necessary.

No coffee coming out of the machine!

First step, increase the grinder size. Note: only change grinder setting while the grinder is spinning. If that does not work, look into cleaning your brew group screens. The machine should have came with a key to remove the screen. If your machine as a preground option try making a preground coffee without inserting coffee to see if only water will come out. If water comes out then you know its your grinder. Usually too small of grinder sizes will stop water flow.
