Troubleshooting Brotje Energy Top 24CTE Boiler - Persistent Error E01 After Power Plug Disassembly

Hello,

Boiler: Brotje Energy Top 24CTE.
Symptoms: Error E01. I did a bug reset as described in the manual probably 50 times and nothing.
This morning I heard the boiler go on for a while, something hummed and it turned off. The whole thing lasted about 2-3 seconds.

The problem appeared after I disassembled the boiler's power plug (I had to pull the cable behind the cabinet), then reassembled it and plugged it into the socket.
After turning it on, everything seemed okay - the display did not indicate anything, but after turning on the hot water, the boiler would not turn on and this error appeared.

Then I had to leave the house and came back after about 1h. The display still showed an error. I looked through the manual and found a record of L / N polarity. After checking the plug, I found that the L / N is altered with respect to the poles in the socket (it actually flashed through my mind when I first twisted the plug, but found it wouldn't matter). I corrected the poles.

I had a phone call yesterday with the fitter of this boiler and he pointed out this polarity to him after I mentioned the plug to him (except that I already found it in the manual earlier) and told me to try to reset, because E01 should be able to reset.

The change in the plug did not help. There is an E01 error all the time. Reset also does nothing.
The problem I have is that it is a holiday and weekend, and I have neither hot water nor heating at home :-)

I would be grateful for any suggestions.

Hi

I do not know if it will help, but I found information that the fault can be removed with a reset only when the letter R is displayed under the fault symbol (eg E01). Moreover, the boiler can be armed only in five consecutive attempts, after which the boiler locks. To have five tries again, turn the selector knob to the OFF position for at least a few seconds. When you try to reset, turn to R for at least 2 seconds.

Here you have the link to the manual: http://pliki.bimsplus.com.pl/Broetje/download/IM/IM_ENERGY_TOP_PL.pdf

you're interested in pages 6 and 7.

As if nothing worked, I would turn the boiler off for half an hour and try again. Regards

Thanks.
That's exactly what I did - five arming attempts, then 5-6 seconds OFF, and again 5 attempts.
There is R at the bottom of the display, according to the instructions, the error can be cleared by reset.

This is what it looks like:

E01 blinks of course.

I'll try to turn it off for half an hour. We will see what will happen.

EDIT: I disconnected the power for 45 minutes. After turning it on, I did 10 resets. Without result.

My friend and when you turn the knob, there is some reaction on the display? Because if not, then you have a broken knob at 100% this is often the case with these models

Swap the phase and neutral conductors. He is polarity sensitive.

There was just no reaction. I thought that this error was so serious that the boiler did not respond to the position of the knob - no matter if OFF, summer or winter, the display always showed E01 :)

And it turned out to be a dial.


After replacement, everything works as it should. The short-term polarity reversal in the plug, which I mentioned in the first post, had no negative consequences.

I'm glad I could help

As I wrote in the post above, the source of the problem was the knob.

Interestingly, I was always rather gentle with him. I heard they were quite brittle, but I didn't know they were so
