Saeco Exprelia - Filling the water circuit and the message restart the machine

Hello!

I have a problem with my coffee machine. When switching on, a message is displayed that the water circuit is being filled and you can hear it pumping water, but the process does not end because the message: "Please restart the device. Problem E05" pops up.
I will only add that a month ago I also had a similar situation, but I rinsed the block well and the problem disappeared. Yesterday, an icon appeared on the display that I need to descale, but I don't think that's the reason, especially since I descale every month.

It seems to me that it is the pump's fault, because after a few attempts to turn it on (after 30 seconds, as it is written in the manual), it finally made me coffee, but immediately a message appeared to empty the water tray. After pouring out the water, the machine started to fill the block with water and after a while the message with the problem E05 again.

Thank you in advance for your response.
Luke

hello, I have the same problem, did you manage to diagnose what is the cause?

Hello, has anyone dealt with this problem? I have the same problem as described above. Please help.
Regards

Hello ! Coffeemaker "does not see" the flow of water. Most likely there is a blocked steam boiler. For starters, it is a good idea to pour in a good dose of descaler and try to rinse the device. If it doesn't help, then just demolition and search for where it got stuck.

Hello.
In my case, when the E05 error appeared in Saeco Exprelia, the reason was the heater clogged with limescale from the water.
After the fact, I know that it would be enough to remove only the back cover to get to the heater. In a working heater, it was possible to insert the probe in the form of a hex key, about 10cm long, deep into the heater's supply hole with water from the pump. It was also possible to blow the heater and rinse it with water, but in a clogged one it was out of the question. In the service manual, to the aforementioned heater connector, a tube with the number 26 is attached, as marked in table 6/9.
Having a choice to buy a new heater for PLN 110 + shipping or try to repair and possibly buy a new heater, I took a 3mm drill and started drilling delicately. When I saw a stone deposited from water on the drill, I drilled bolder until the drill "fell".
After folding, the water circuit became blocked and the heater is still functional and the message / error E05 does not appear. The repair cost about PLN 5, because I put new clamps on the water pipes. I bought them at an auto parts store.
I would like to add that the first signs before the E05 error appeared were problems with milk foaming.
I attach photos of the heater that I was repairing.

For people trying to disassemble the Saeco Exprelia type HD8856 / 09, I will suggest that first you need to unscrew the back cover, which is well described in the service manual (I found only the English version), then you need to disassemble the upper part of the housing, which the manual did not mention. I am attaching photos showing where the latches blocking the disassembly of the top were located, even though I unscrewed the screws holding the top casing (4 pcs.). Undoing the four latches holding the top was an acrobatics for me.
After removing the top, two screws were exposed, located in the front upper part of the coffee machine on the left and right side.
I greet the designers of the device, because they THOUGHT what to do so that it would not be easy for us to get inside. These screws, covered with the upper case, could be left on top, leaving the holes for unscrewing them, and inserting the plugs.
Disassembly would then be much easier. Moreover, even the service manual did not mention these two screws.

E5 is no reading from the flow meter. The reasons are three: 1) - the system is clogged with limescale (everyone says that descaling the question is only what I know aces, what they buy any cheaper and then surprised with the clogged descaler, the descaler is not equal to the fact that the kettle does not mean that it is good for coffee machines) 2) - not doing cleaning the brewing group with a suitable tablet (this message is not displayed, you must activate it yourself) if this cleaning is not done, the upper sieve of the brewing group is clogged with fat contained in the coffee, it remains to open the sieve, scrub and start the cycle with the tablet. 3) - defective flow meter.

I would like to add that I descale using Saeco products always within no more than 4 days from the message. The entire system was not stony. I looked into the pipes and valves and only this heater was clean. After this adventure, I wonder if I should start using vinegar for descaling. Maybe it will do better.

Usually, a pin is made in a thermoblock due to the small diameter of the pipe through which the water flows, the silicone pipes have larger diameters and are slippery inside, which makes it difficult to deposit stone. By pouring the vinegar, you will make the coffee maker even bigger. A good descaler is supposed to dissolve the limescale, and not to dissolve some of it as vinegar, and to split some of it, if the pump pumps the debris into the thermoblock, it is wiped away. When the plug inside the heater is made, you will not unclog it with any drill or wire. I always recommend that my customers pour in the entire 250ml bottle. Saeco descaling agent, add 250 ml of warm water to the water tank and descale this proportionally.

Thanks for the advice.

Bands purchased in an automotive store (twisted) are not the best solution, look for clamps like they are originally fitted. Size 9.5mm.

I bought twisted. Can they pass because they tighten unevenly? During the tests, the operation after the repair did not pass. They firmly fastened the wires on the connection tubes. Or is there a risk that it has burst due to thermal stresses?

You can buy the bands at pressure hydraulics stores or at the north.pl store.

How to remove the zip ties without using special pliers?
Is it possible to buy water pipes with red braid somewhere?

Hello
The reason for frequent filling of the water circuit and lack of preliminary rinsing is the air in the water pump ....... the sensor sees air in the circuit and disconnects it with a safety valve,

SOLUTION deaerating the pump in a very simple and quick way, just lift and lower the water container, do it quite quickly, at least 10 times and the pump will vent itself using this valve

In case of other problems, please visit PRIV

I have the same problem. Your way is effective. However, I have to do it every time the machine wants to start cleaning. Have you found the target solution?

Hello buddy
If you still have this problem, remove the brew group and clean the brush, guides from the inside, and then lubricate it, then manually try to move the mechanism all the way and back. The water nozzle probably does not come to an end and therefore releases water through the safety valve

Regards

I will join the topic because the E05 error was popping up.
It turned out that it was dripping on the flow meter with the ring above the vent valve (aswo documentation no. 30 p / n 20006558). I drain the water with a handkerchief, the error does not pop up, but drips. I do not fully understand the principle of operation and the moment of switching on this system and why it is dripping ...
I checked the hoses, patency and nozzles as if everything was ok (makes coffee, froths milk, makes steam) and still drips.
At what point is this valve supposed to work?

It is not a valve. He's counting the flow of water, let's say in liters. Hence the name flow meter. This could be a good clue as it has wet contacts, it can plant mistakes. For me, no errors pop up, only has a problem with the initial cleaning.

I did not mean the flow meter, only in this model there is a valve just above the flow meter and water flows from one of the seals. The seals of the replaced cracks cannot be seen and the water is dripping.

I have such a problem, apart from the above mentioned one, which has not been solved yet, because I didn't get down to it.
During descaling, the machine cannot see the drip tray when it needs to be emptied. By trial and error, the machine is finally started. Oddly enough, when I put in the grounds container alone (I put it on a rug), without the drip water container, no problem. No problem during normal operation either. Only during the descaling process.

I also have the same problem, indeed the cloth helped, but what's the problem?

I know what the problem in the coffee grounds container is the magnet that activates the sensor and the sensor does not detect it. There is no container filling sensor, only the sensor that detects the removal and insertion of the container, I solved this problem by sticking a small neodymium magnet to the existing one and it works. The problem is either with the magnet or with a sensor that doesn't detect it.

descaling.

Hello everyone, I also get the same error from time to time. Then I turn on the descaling cycle, but it lasts maybe 2 minutes, it does not even drain the entire descaler from the container, then orders it to be poured out and starts rinsing. And here's my question, where is the problem? And I also mention that the coffee has been nasty lately . Any advice or some good service that will bring the equipment to its former glory.
Best regards, Marek

This month I had three such models with identical symptoms.
In all of them there was a damaged solenoid drain valve which caused a leakage centrally to the flow meter.

How long should the descaling cycle be?

From what I remember it's quite a long time, Long rinses. The whole thing is 20-25 minutes for sure.

For me, it takes about 2 minutes to descale the strip when the descaling cycle fills up completely at the very beginning, at the end it will pass the descaling solution a few times and tell you to rinse it

What is the cost of such a repair?

Hello ,
I have a similar problem with filling the water circuit, and while brewing the coffee machine opens the door and stops working, I tried to hold the door firmly and I managed to brew, but some water leaks from the block into the coffee grounds container and outside of it.
Help what's going on, if anyone has met with something like that, I will be grateful for your help and any suggestions.
Regards

The brewer is probably the cause. It should be disassembled, washed, cleaned, lubricated with appropriate lubricants, and the seals on the brewing unit should be replaced (it should look like new). It usually helps.
