Philips Saeco Exprelia HD8854/09: Water Circuit Filling & Flushing Issues, Error E03/E05, Pump

Hello

I’m having a problem with my Philips Saeco Exprelia HD8854/09 coffee machine.
When I switch it on, it displays the message: ‘Filling the water circuit’, followed by: ‘Rinsing the circuit’.
Even though it repeats these steps several times, not a single drop comes out.
I’ve had a similar problem before, but back then it displayed error E03 (or E05 – I can’t remember now). The service centre said they’d replaced the pump and everything was fine for the next 2+ years. But over the last month the problem has returned; admittedly, it did make coffee this morning after a few attempts, but now, after a dozen or so attempts, I’ve given up.


Do you have any ideas as to what might have happened?

Best regards,
Andrzej

There can be many reasons ...
Starting from the flow meter itself ...
The entire water system should be checked for patency and correct pump pressure.
Without this you can go on forever ...

The last copy of this model with such a problem had a clogged door valve.
But as I mentioned above, it may well be the other side of the system ...

Naturally, I do not want to bode badly, but I know from experience that trying to make coffee by force does not always result in self repair.

I tried a few more treatments and at the moment I managed to make coffee.
We'll see how it will be tomorrow morning.
Tomorrow I will write what I did and with what results.

It is clogged somewhere, you can clearly hear that the pump is going down is a basic sign. The fact that error 05 doesn't crash is because the tachometer gives a signal to the electronics when the safety valve opens when the pressure is too high (you definitely have water in the drip tray) and the water flowing into the tray turns a little bit. The problem lies in the coffee circuit (because it blocks during this test). When the machine tries to do the rinsing, stop the cycle, remove the block, then on the back wall there is the brewer finger with two red seals between them is the crossbar. Use a flat screwdriver to lift it up (wrap your hand with a cloth so as not to burn) when the bar is lifted up, the valve should spray water under pressure, if recommended, look for blockage in the brewing block (upper sieve clogged - no cleaning with the tablet, valve clogged) nothing will fly without unscrewing and searching in the internal water supply system to the block will not do. Try to turn the knob on the coffee spout a few times while rinsing, one at a time.

Thanks for the advice. I will definitely try.
I will only add that I tried this "myku":
-when trying to fill the circuit (as in the attached video, the water is in the tank) and attempting to rinse the circuit, I stopped rinsing myself, then tried to pour water only through the "Hot Water" function and works without measuring the right amount of water.
- then I launched the "Cappucino" function and to my surprise it was prepared correctly, followed by a cleaning cycle of the jug and rinsing the circuit after the coffee machine was finished. And all without any problems.
So I am still thinking about the constant filling of the circuit. But maybe this will change as I follow your advice.

The "hot water and capuccino" circuit is two separate circuits, see with this valve, if the water does not fly after raising the bar, the coffee circuit is clogged, if it recommends, look for blockage on the brewing block side (block pipe wiped, or currant itself 0 Clogged sieve.

I checked exactly what you described. When the valve is released, hot water / steam escapes.
At the moment I know that the problem is rather the side of the valve you are talking about, or the "pipe:" that opens it.
I unscrewed the block myself, checked it, additionally cleaned it, but I did not notice any problematic point, everything was unobstructed.
Do you know how to check the elements mentioned above (which one is damaged) or where can I get these parts? Can you recommend someone at reasonable prices?

I will only add that after interrupting the rinsing cycle, I can still prepare any type of coffee.

Andrzej, has the problem been solved? I have the same situation and I'm at a glance what to do

Finally, the coffee machine came to the service a month ago and the pump and one of the valves were replaced. Unfortunately I don't remember which one.
Now works correctly.
The cost of the service, including parts, was PLN 520.

I had this situation, the valve above the flow meter leaked straight onto the flow meter. The contacts on the flow meter faded and gave no impulses that there was water flow and an error occurred. It was enough to clean the contacts and replace the seals with the collar.

For me, the breather valve in question does not pour, the flow exchanged, clean plug. The pump supplies the correct pressure. Replacing the valves as soon as I get this opportunity

I finally came to what causes problems with filling the circuit. The plastic body above the breather solenoid valve is the culprit, it is broken and needs to be replaced. After replacement, the problem goes away. I warn you that the seal alone gave nothing.

Hello For 3 days I was struggling with error 05. After deodorizing was turned on, it was buzzing (sometimes block filling error) and it did not release water and it went to phase 2 (which worked fine), cleaning the block also blocked it, only rinsing worked. I took out the boilers (they were free), cleaned the hoses, cleaned the block strainer and the ball pin from the top, cleaned and greased the valve behind the block (the beige one), disassembled the flow meter, cleaned the door adjustment valve, blown the vent valve above the flow meter and it still did not work. I was already wondering whether to throw it away, the service said that the repair with such symptoms can amount to over PLN 600. It would probably be better to add and buy a new one. I ordered a north pump for PLN 74. Something touched me and I unscrewed the solenoid valve under the deaerator, pressed it a few times and put it on, the coffee machine worked, all functions started (I decalcified and cleaned the block with a tablet). To sum up, it was enough to unscrew the solenoid valve and move it by pressing (it helped me), since I had already bought a pump (replacement) for a 48W ulka, I put it on (it walks quieter and gives water evenly). If someone had saeco hd8856 / 09 to throw away, please let me know at jaro83(_at_)gmail.com (it may be useful as a donor, some plastics are damaged).

Anyone having problems with rinsing cycle or filling the cycle, priming - in 98% of cases it is water pump. And there is no need to buy a new one, as just simple valve ball/seal replacement fixes the issue. Cost just a few euros. Like here: https://www.ebay.co.uk/itm/292493508587

Hello everyone.
I'm struggling with a similar problem and I'm just starting to find the cause, and in the process I'm replacing the gaskets and balls in the pumps, as the machine will be over 12 years old now.
I see a leak on the solenoid valve (highlighted in blue in the photo) - I have already ordered new gaskets.

.

In the hoses I discovered a deposit (marked in magenta in the photo), rather dark, it does not look like a scale, but either a coffee deposit (???) or some organic impurities (read: mould (?))....
Question for you: how to clean this throughout the circuit? Generally, there is a remedy for limescale, but for dirt like this I don't really know what to use, apart from manual cleaning.
On top of that, while I can see the cleaning effects in the transparent hoses, it comes with difficulty in the braided ones and the only idea I have is to replace the braided ones completely. I assume the same is true of the pumps and boilers and here I am completely out of ideas.

It may not be a big problem, but I prefer to ask now that I have access to all the guts and not downplay it.
Thanks in advance for any help!
