Immergas EOLO Star 23 kW: Encountering Error 03 After Resolving Error 11, Fan Not Starting

Hello !
The fault occurred during the evening shower.
Error 11 came first.
I'll turn him on
And he is now error 03 (orange)
And I'm green because there is no such error in the manual (it's 01.02 then 04).
The chimney is clean, the fan is not jammed, the pressure switch tubes are clean (if you puff, it clicks normally).
Who has any idea what's next?

When the cw tap is unscrewed, the fan does not start (no voltage on the contacts), but I have already lost my mind whether it starts before or after the ignition



Thanks in advance for your help

Probably the motherboard

It can be fixed.

Start the pressure switch on the fan probably stuck

hello, maybe this will help someone...

same problem as colleague (error 11 on display)

scheming, undressing, peeking and what?

it turns out that the stove gets too little air for gas combustion (closed chamber).

it happened because I installed an anemostat behind the air intake and twisted it too much.

after increasing the air supply, the problem disappeared.

There is something about it. My air intake was almost completely icy. I had to clean up.

for me it turned out that error 11 was due to the fact that water (rain) got into the fan from the chimney

Water got into the fan and it wouldn't spin? was there an error 11 despite the fact that the fan was spinning?

after disassembly, it turned out that it did not even fire because even the burners were flooded, after drying I fired it and everything still works

WELCOME, I'm joining this thread because I have error 10 (blinking yellow) I tried to fill the installation with this small round black plug but it doesn't work, (the pressure does not rise) My stove is immergas eolo star 23Kw

Either the pressure sensor has failed or (at worst) the electronic board.

Hello everyone, I have a question for users of the eolo star boiler with a closed combustion chamber, what are your opinions about the boiler, what is your winter combustion?

Dude, I have a stove like that. In my case, it heats about 60 m2 - the temperature is constantly set at 22.5 degrees. I have a comprehensive contract (i.e. heating the apartment, hot water and a gas hob). My worst 2 months cost PLN 970, although they were very frosty. My annual cost is less than $4,000. I would like to point out, however, that I do not have a hall in the apartment yet and when leaving the apartment a lot of cold air attacks the apartment.

Hello friend, I have 75 meters to heat, I also have a gas stove and this stove. My bills for the whole year are PLN 2600. I heat on the day 21-22 at night 19 degrees. At the beginning I was in the tariff in 2.1 but that my consumption is above 1200 meters per year until I was transferred to the tariff in 3.6 where transmission fees etc. cost about PLN 120 for 2 months, and in the tariff in 2.1 there was a fee for 2 months about PLN 50. Apart from the fact that in the tariff in 3.6 gas is slightly cheaper than in the tariff in 2.1. for now. I also have a tybox 810 wireless sensor and so far I don't think I pay much.

The annual settlement came and the forecast for the next year - the projected cost is something around PLN 3,200. I need to build a hall quickly.

Ps buddy above and how do you set the water temperature? I have 46 degrees (and as I wrote earlier, the temperature in the house is 22.5 all the time) - my wife often opens the windows to ventilate the whole apartment (so this should also be taken into account - with the temperatures that are currently prevailing, after less than 30 minutes the temperature in the house drops to about 20 degrees, so the stove starts up on a regular basis later)

I have a water temperature of 50 degrees on the stove. If you have PLN 3200 per year, what is your gas consumption per year. Because something doesn't suit me here. You pay a fixed amount every 2 months throughout the year, right? Because I also had bills forecasted, but my consumption was quite high, i.e. over 1200m per year and they transferred me to the tariff in 3.6 and wages every 2 months as much as I use up as much wages.

Sorry buddy, I was wrong now we received the forecast for PLN 2,600 because we had an overpayment, so the first invoice to pay is March for the amount of PLN 520 (for 2 months).

1 question about the cost spoiled the thread a bit, and the subject is an error.
Does anyone else have this five?
I get error 03 from time to time. Twice in a row when c. water was flowing on the shower valve half open. Could it be the heat exchanger overheating?

Hello gentlemen,
On Sunday morning, error 03 was displayed and the stove stopped working.
According to the manual, fan error.
I disassembled the fan myself, cleaned it and oiled it with WD40, because it was heard that the bearing was slowly seizing up.
After all, the stove after connecting and turning on the fan after 10-15s showed error 03 and the fan ended. There was no ignition. The fan worked fast at first, then a little slower.
Chimney checked, air supply all unobstructed, etc.

SOLUTION:
The next day, the installer Immergas was called.
The first step is to check the fan voltage and diagnose: the device is not expelling.
Replaced with a new one (he had it with him).
Immediately after replacement and connecting to electricity, the stove starts with a hoof.
Everything as it should be.
It's just for those looking for help as I have solved the problem 03.
I will only add that the fan was already 8 years old.

I confirm. Replacing the bushings with bearings solved the problem for me. The windmill must be pumping otherwise 11 and 03 will pop up on a regular basis. The electronics in these boilers do not break down. 14 years old and walks like gold. Everything original except the bearings in the fan.

Hello, yesterday error 11 popped up on my stove - which is associated with the lack of hot water in the tap. I read on the forum information that probably the fan or pressure switch will burn. I dismantled the stove to check the exact model of the pressure switch. I put it together and checked if the fan turns on. Unfortunately, the fan did not move when the hot water was turned on. I checked it with a meter and there is no voltage going to it. There was also no voltage at the plug on the board to which the wires going to the fan are connected. The relay normally ticks as if it were switching on but the current does not release. Then only error 03 started to appear. I managed to borrow a board from the same furnace and only the furnace started working. I also noticed that at the plug from which the wires to the fan go, both are swollen. The other wires are OK.
So in my case the problem lies somewhere in the electronics on the board and not in replacing the fan.

By the way, I'm curious if maybe the relay is failing?

Buddy, move this pressure switch to the right of the pump, it did not touch me. After replacing the board, you could just move france.

Nike Star stove. For some time, errors 03 and 11 began to appear. I called a service technician, he inspected the furnace, cleaned everything, and the next day the errors appeared again. The service technician came again, this time he replaced the fan and the pressure switch (that`s what it`s called ). For a few days the stove worked without any problems, then after 4 days error 11 started appearing again. Additionally, when using water, hot water suddenly stops flowing for about 1.5 minutes. ice water flows, then warm water starts flowing again. Does anyone have an idea what else could be causing the error?

You probably have EOLO STAR and not NIKE STAR.
But to answer:
The reason may be:
1. Chimney - blockage of one of the chimney flues (oxygen or exhaust gases).
2. Breakage of the hose from the fan to the pressure switch.
3. Fault on the motherboard.
4. Of course, there is also the pressure switch itself - once it happened to me that the new one was defective.
5. Fan - if it is new, it may be installed incorrectly
6. Clogged choke in the fan

Hello,
I'm having a problem with error 11, Immergas EOLO STAR.
In my case it looks like an electronics problem, but I don't know how I can check it exactly.
I am an electrician, not an electronics technician, but with your help it might be possible to diagnose specifically what the problem is.
I have checked the patency of the hoses from the pressure switch and the fan itself (they look ok).
There is no voltage coming from the board to the fan.
Attached is a video of what happens when I turn the hot water off. .

Replace the relays. And preferably the capacitors at once.
All electrolytes.
Replace all components 1:1 with EXACTLY the same ones.
If you are not proficient in soldering, contact an electronics technician.
The Immergas circuit board is a little fragile and it is easy to chip the tracks.

Thank you for your quick response.
But that doesn't solve the problem of the cooker not working on Sundays ;-(
I am sending a picture of the board.
PS. You can hear the relay ticking after turning on the hot water.
I don't think I'm going to do it myself, even though I'm good at soldering, it's a time-consuming task to gather parts etc.
I'm pressed for time, so I can either buy new or reconditioned electronics. (How much does it cost to remanufacture such electronics?)

.
I would like to be sure that this is the fault of the board and not some other component of the cooker. That's why I asked for help in diagnosis.

The relay "ticks" but if you open it and look at the contacts you will understand.
