In detail: do-it-yourself eberspacher control unit repair from a real master for the site my.housecope.com.
Our company produces repair of any control units Eberspacher heaters, including the Hydronic and Airtronic ranges. We have been providing this service for more than nine years and we have accumulated a colossal and probably uncontested experience in diagnosing and repairing the Ebershpecher control board. For Eberspacher repair and diagnostics, we use professional equipment and original parts. Each unit must undergo a test run at the stand for diagnosing and reading errors, and two cycles of work with a controlled pause after the completion of the repair.
Special conditions for repairs may apply to the control unit for the Hydronic II heaters. We consider it inappropriate to repair these units, then repairs can only be carried out at the insistence of the client, with a limited warranty and extending only to the check when installing the control board on the heater.
The warranty for repairs of other control units is 3 months.
The creation of this topic pursues one, but very important idea - to try to repair control units on your own, because the difference in the cost of a new unit (15 thousand rubles) and p / parts (10 - 1000 rubles) is incommensurable, so it makes sense to do it. I suggest everyone who is interested to post the redrawn schemes (in whole or in part) in the topic. And the experience of repair, if possible, then maybe we will overcome this problem. Specifically, I am currently interested in the Hydronic B5 WS control unit
p. s. Please do not repeat the materials about the opening of the sealant, etc., discussed earlier.

Hey! Today I disassembled the electric motor again, found the reason for the wedging, in general I found out 2 points: Firstly: it turns out that the armature and its contacts move along the shaft, I did not take this into account when I stuffed the bearings. Although this is neat, due to the beating, the anchor moved and began to wedge with contacts in the counting unit. Put it in place - everything is stall like a needle. And secondly, everyone will probably be interested:
... replacing ordinary magnets in the case - changes the polarity and direction of rotation.
This knowledge did not cost me a bedroom impeller. Well, I could not even think that the pidantic Germans made grooves everywhere, there was no way you could assemble it in another way, but the usual two halves of the magnets were not even marked with paint.
And therefore the question is about the brains. I have an assumption that perhaps there was a problem of sudden stop and the brain had nothing to do with it. But maybe due to the wedging of the motor, the ground contact on the board burned out. Once I heard an advice - to check this, move the contact of the mass of the electric motor to the place for the contact of the mass of the electric pump. I do not have a D5wz electric pump (it costs separately) But BU with the compact model are the same, as I understand it. And probably there is a leg of the mass under the pump? What is the question, number 13?
This is an oval connector. Or 11 pins?

Hello, please tell me to what temperature the ecu are you heating up to get the board?
... guys. clearly not stupid. leading. myself. like assholes.
If it's not difficult, you can not use such wide-angle lenses, it is stressful to watch.
Roman Zhukov will try to think of something. There is only gopro for now
Hello, where are you? I have a heater Eberspächer Germany B5WS 12V (with an external pump) without a remote control with a button, it is out of order and I don’t know where it can be repaired, can I send it to you by mail to fix it?
Hello vector, please send, St. Petersburg. ± 79119266587
Tell me where you get the graphite brushes for the supercharger, otherwise you are tired of sharpening
EasyCheck or at starters or in email for example
Serg Prostyakov until they met you, it was no fucking thing to do. Everything has changed, where to buy :)?
EasyCheck don't give a fuck to you, these brushes are 150p worth
I got carried away with the bulkheads of these furnaces, the volume of work is normal 🙂 we sharpen graphite brushes with pens, it takes 5 minutes, it is easily washed off the hands, I do not see the need to look for ready-made options, and it’s not so easy to find them, I tried.
copper-graphite brushes eat up the collector, brushes from 220V electric tools have resistance, which affects the rotational speed of the blower. So you have to look, sharpen, hassle, especially not very much with large volumes of work

The toad choked me to buy a duyka for a very long time, until I found out about Planar. I have worked for six years now, it is cool here not only in winter. Rearranged it from the previous car. I have never looked into it. Occasionally it refuses to start (it lights up from the second poke) and makes a terrible noise. I want to change this summer for a new, 44th, they are quieter.
Before, there was an opinion that German duiks were unkillable, but it turns out, no. And after all, the difference in price with Samara hoo! Maybe sometimes it is worth supporting a domestic manufacturer?

The Eberspacher HYDRONIC control unit is an electronic printed circuit board enclosed in an aluminum housing filled with a compound.The printed circuit board contains electronic components responsible for the operation of the heater as a whole, and each component is responsible for a specific function in particular, so the most common mistakes on the Eberspacher HYDRONIC 1 are:
30 - The fan motor speed for the intake air is out of range
31 - Air intake fan motor - interruption
32 - Air intake fan motor: short circuit, overload or accidental ground
The reasons for this error may be:
Changed geometry of the blower impeller from overheating or time, the impeller is made of plastic.
Sour bearings of the blower due to constant temperature fluctuations, condensation forms in the housing even in summer.
Development of the rotor shaft of the blower motor
Development of blower motor bearings
Well, the short circuit indicated in the error codes (extremely rare)
Other errors in which it is necessary to repair the Eberspacher HYDRONIC control unit
As well as errors that do not fit with the diagnostic readings for peripheral devices
Non-diagnostic control unit
Not always services equipped with diagnostics can correctly recognize the error code on the control unit, so, having wedged and lubricated the fan motor, removing the errors, the owner leaves satisfied with the result of the work, but after a while he returns to the service, all with the same error 30,31,32, at the same time from the crown of 9 volts, the fan motor works perfectly.
The reason for this is the cunning electronic components that tried to start it at the moment of the fan motor wedging up, burning inside, they begin to fool the microcontroller - the processor, issuing various error codes and blocking the operation of the heater - heater.
Treatment - Repair of the Eberspacher HYDRONIC control unit is 5,000 rubles (1 year repair warranty)
