DELONGHI Coffee Maker: Clogged Strainers Solutions - Cleaning Brushes, Citric Acid, Valves

Listen, I don't know what to do anymore.
Everything points to the fact that my sieves are so clogged that there is no coffee coming out at all, the water pressure is for sure because only pure water is released with the sieves removed, the valves, as I do not know. I scrubbed these strainers with brushes, soaked in citric acid and nothing.
What other options are left for me ????

1 / Buy new strainers on the site.
2 / Check with a different type of coffee
Ev. service as it may be too low vapor pressure. What you can not check "by eye".

Hmmm, but the water does not run even when only the strainers without coffee are inserted.
Let's see, I will try 1 strainer first with the purchase

Well, 95% - bad news - damaged pump. I think it will be difficult without the service ... but because this is bad news, maybe someone else will have an idea ..
Good luck

What exactly is this coffee machine?
The strainer (with holes) is clogged or the Crema filter?
How old is the coffee machine?
What is the hardness of the water?
What coffee do you use for this machine?

The coffee machine is a Delonghi 300, the screens where you put the coffee are clogged, as I looked at them under the magnifying glass, each hole is surrounded by a small black border.
The coffee machine is about 3-4 years old.
As I wrote, the water flies without a problem when there is no strainer
I use coffees intended for the coffee machine
I do not know the hardness of the water

So it's the EC 300, the strainers, it's a Crema filter ( Link ).
Did you disassemble and clean it regularly?
A total of 3-4 years, it's probably a filter to be replaced. The pump will be rather operational.

Well, I don't know where the filter is, is it the strainer that is kept underneath in the coffee machine by a small screw ???
Yesterday I unscrewed this screw, took out the strainer, cleaned it and screwed it on again.

The filter is the one you pour your coffee there (unless you have a different one). There were these filters for 1 or 2 cups.

Well, but in this filter there is probably nothing to get clogged because there are 2 large holes and a recess into which these strainers are packed in such a metal housing.
Something in this filter needs to be cleaned ????

The best part is that I have the instructions, but no drawings.
This is a quote from a manual I found on the web:
"cover.
o Remove the gasket.
o Rinse all components thoroughly
clean the metal filter wiping with warm water
brush (fig. 23).
Check that the holes in the metal filter are not
clogged. If so, clean them with
pins (see fig. 24).
o Reinstall the filter and the gasket on the plastic
the dial as shown in Figure 25.
Be careful when inserting the plastic plug
on the blade into the seal hole indicated by the arrow on the
Figure 25.
o Put the received set into the steel adapter
onto the filter (fig. 26), making sure that the pin remains
correctly inserted into the base (see arrow
in fig. 26).
o Finally screw on the cover by sliding it
clockwise (Fig. 27).
The warranty will be void if the above
cleaning will not be performed regularly
carried out.
CLEANING THE BOILER OUTLET
The boiler outlet should be cleaned at approximately every 300 coffees
as follows:
1. Make sure the coffee machine is not hot and
the plug is removed from the socket.
2.Use a screwdriver to loosen the fixing screw
espresso boiler outlet filter (fig. 28).
3.Clean the boiler thoroughly with a damp cloth.
4.Clean the boiler outlet thoroughly using warm water and
rub with a brush.
Check that the holes in the metal filter are not
clogged. If so, clean them with
the pins (fig. 24).
5.Rinse the boiler outlet under running water, always
wipe.
6. Reattach the boiler outlet.
The warranty will be void if the above
cleaning will not be performed regularly
carried out.
DESCALING
It is recommended to descale the machine
after about 200 coffees or a maximum of
two months of use.
It is recommended to use special products for
descaling espresso coffee machines that are
available on the market.
If these products are unavailable, you can take
following steps:
1. Pour about 0.5 liters of water into the water tank.
2. Dissolve 2 tablespoons (about 30 g) of acid in it
lemon (available at pharmacies).
3. Press the On / Off button and
wait until the OK indicator light comes on.
4. Make sure the filter adapter is not
attached and place the receptacle under the outlet
devices.
5. Press the brew button, allow
half of the solution contained in w drained out
container (turn the knob from time to time
steam and drain a small amount of solution), a
then press the brew button again.
6. Switch off the device.
7. Let the solution run for approximately 15 minutes
minutes and then switch the machine on.
8. Press the brew button until complete
emptying the tank.
9. To remove residual solution and sediment
calcium deposits, rinse the reservoir well,
fill it with fresh water (do not dissolve it
citric acid) and put in its place.
10. Press the brew button and let the solution
it flowed all the way out of the reservoir.
11.Contain the flow of water and again
repeat steps 9 and 10. "

I don't know what to do

Wrong.
Link this is a grip / stock.
Link it is a filter.
The photos may be slightly different as this is just to explain what what is.

The filter consists of three basic elements (as shown earlier). At the bottom, you unscrew the black cap and push the center of the filter out of the metal housing.

Normally, every dozen or so coffees should be unscrewed and washed the filter elements. But now, it only remains to replace it with a new one.

I add drawings - how to clean:

Oh, thx now at least i know what's what.
So it remains to buy a new strainer or the entire filter and how much does it cost ???

You can still try to open it and clean it. If it doesn't help, it's new. Price around PLN 35 total ( Link ).

The best thing is that when released by the strainers itself, it flies without any problems, but the flow of water is blocked by the black element on which the strainer lies and sticks tightly to it.
What could that mean ???
I checked it many times, it is sure that the filter is properly assembled and cleaned

This item includes a pressure valve. It is probably damaged.

How to check it ???
What should be seen, here is a photo please
I just don't know if they will be visible
It is intentionally brightened

Look, I fixed it !!!
There is a spring in this black one and it holds something that was twisted and I corrected it and it works !!!

Well then congratulations! Good to know! Always a few zlotys in your pocket!

Heh thanks, but I tried to figure out what happened.
I wanted to give up and buy new ones, but I went by elimination.
The coffee machine is cleaned like never before

Hey, I had a problem with a clogged strainer
I knew that it was a strainer, and not another fault, because the second strainer, which was included in the set, could make coffee.
I put the strainer into boiling water with citric acid. I held for a few minutes and it works as before.

I, in turn, treated the strainer as above after clogging with all the specifics and nothing helped. Finally, it helped to make the strainer red hot over the gas, hold it for a few minutes for the muck to burn out and then throw it into cold water. Works like new. Kisses
