Resolving De Dietrich Lumea MPX 20/24 Ignition Fault (Error 133) after Gas Valve Shut-off

Question

Colleagues, I have a problem with the stove. The wife turned off the gas valve under the stove in the morning, probably turned on the water several times during the day, error 133 appeared on the screen (ignition fault - visible in the picture, the screen flashes). After unscrewing the valve,...

But what are you resetting? Nothing? No reaction, is there a reset followed by more attempts to start and again an error?

lukg86 · Answer

There is no reaction. That is, when you press power off, the stove turns off (but the screen continues to flash). Same error screen when turned on.
When pressing the combination of two keys, there is no reaction, the two screens visible in the pictures are constantly changing.
Maybe I'm doing something wrong though? I think I'm sticking to the manual though.
Should there be any reset confirmation?

zales.vip · Answer

The combination will not give you anything because the boiler is in a locked state. Reset as instructed. By holding down the power button for at least 2 sec.
After a properly performed reset, the boiler will start up again and start working.

lukg86 · Answer

That's what I do, pressing the power button does nothing, I held it for more than 10 seconds. To be sure, on and off the stove.
The screen just goes on and off without stopping the backlight blinking.

In case I can't read the instructions, I'm posting a link to a video showing the situation:

There was a service technician just now, reset attempts also failed, complete lack of cooperation from the boiler. Diagnosis - damaged motherboard (560 PLN plus 150 service costs).
Something else inside pokmerał, blew, disconnected the wires and reconnected and - surprisingly - the stove started ...
I'm supposed to watch, he deleted 150.

What he did? He cleaned the electrodes and that's it.

Hello
I'm bumping this topic because I have the same problem. After turning off the gas, error E133 appeared. I have a wired room thermostat connected to the furnace. After connecting the thermostat, the buttons on the stove did not work from the beginning and the installer said that I set everything in the thermostat. Unfortunately, therefore, the reset button on the stove does not work (I press it for 2 seconds - it does not work, nor does it last longer).
I used the reset function on the thermostat, which reset the settings on the thermostat and not the stove ...
Is there any other way to reset the furnace?

zales.vip · Answer

Try turning on the auto calibration function by holding the i/p and heater+ buttons together for 6 seconds.
If the external regulator "blocked" your buttons (it shouldn't) - disconnect it for a while. For the duration of auto calibration and reset. It is under the plate flap on the M2 strip. Just disconnect the boiler first.

He trained you nicely. I had the same case a few ms ago, today it happened again ..... The installer only passed gas to vent the furnace. Just enough. And it works.

Hello everyone!

I'm getting on topic too. I have the same error and I can't reset the boiler either. Exactly no reaction of the boiler as in the previously linked youtube video. Has anyone figured out how to do it without a service technician?
Thanks in advance.

wnojtek · Answer

And was the reset performed according to the instructions, i.e. for 2 seconds or rather for 20 as in the video?

dbst · Answer

It seemed to me that according to the instructions, i.e. for 2 seconds. However, after your suggestion, I did it with special attention to timing. And we did it! A reset has taken place and the boiler has started working. Thank you for your help!

zales.vip · Answer

What kind of regulator do you have? ?

dbst · Answer

I don't have any yet.

We hold reset = 2s and in principle it works.

Problem 133 occurs when the gas pressure drops after closing the gas valve upstream of the regulator. After opening the valve, the reducer in front of the gas meter is still blocked and resetting the stove does nothing. There is simply no gas going to the stove. Just unlock the reducer. The small wire should be lifted up until you hear a hiss. The wire falls freely and then you can reset the stove. Regards m

colleagues, I have a problem with piece de ditrich mpx 24 compact, it shows error 133, restart attempts do nothing. apparently there is a wire at the reducer that can be bled??? Where to find it????

marcin7sobiech · Answer

If you have a gas meter in a box by the fence, there is a reducer next to this meter.
This reducer automatically closes the safety valve if the gas pressure in the pipe between the meter and the furnace drops.
Lack of gas upstream of the stove causes the stove to display error 133.
Try the following:
1. Open the gas valve in front of the gas meter (Probably in the metal box in front of the shack).
2. Make sure that the installation is tight and if so...
3. Lift up the small lever on the reducer.
4. When you hear a hiss, the gas will enter the pipe and the safety valve will be opened.
5. Reset the stove.
Good luck
