Question 1

How to recognize the symbol for the automatic cleaning function on the DE DIETRICH DOP4543H oven?

Accepted Answer

On the DE DIETRICH oven model DOP4543H, the symbol for the automatic pyrolytic cleaning function is a padlock that appears on the display of the control panel.

This padlock symbol specifically appears when the pyrolytic cleaning cycle is activated and indicates that the oven door is locked. This locking is an essential safety measure during the entire pyrolysis cycle, which reaches extremely high temperatures to incinerate food residues.

You can also see this same padlock symbol by activating the “KEY LOCK” function on the control panel, accessible from the main menu. To unlock the keys and unlock the door, press the return keys simultaneously until the padlock symbol disappears from the display.

To start the pyrolysis on your oven, select the “CLEANING” function from the main menu, choose the appropriate cycle (PYRO AUTO for standard cleaning, or Pyro Express for quick cleaning), then set the desired end time. When the cycle starts, the padlock symbol will appear to indicate that the door is automatically locking. At the end of the cycle, let the oven cool down, then wipe away the white residues (ash) with a damp cloth.

Question 2

How to activate the pyrolysis cleaning function on the DE DIETRICH DOP4543H oven?

Accepted Answer

The DE DIETRICH DOP4543H oven features a pyrolysis self-cleaning function that eliminates all dirt (splashes, spills) by heating the oven cavity to very high temperatures. This function has three cycles with preset and non-modifiable durations: Pyro Auto (1h30 to 2h15), Pyro Express (less than one hour), and Pyro 2H (2 hours for deep cleaning).

Before starting: Be sure to remove all accessories and racks from the oven, as well as any containers. Remove significant spills and excess grease on the door with a damp sponge. This step is very important to avoid damaging accessories that are incompatible with pyrolysis (sliding rails, chrome grids).

To start a standard pyrolysis cycle: Access the cleaning menu on the oven's control panel. Select the self-cleaning cycle that suits you (for example, Pyro Auto), then confirm. Set the desired end time for pyrolysis using the knob, then confirm again. The countdown begins immediately, and the door locks automatically. A padlock symbol appears on the screen to confirm that the door is locked.

Option at the end of cooking: If you choose Pyro Express at the end of cooking, select “End of cooking” in the menu. After a few seconds, the oven goes into standby mode and the start of pyrolysis is delayed to finish at the scheduled time. This option takes advantage of the accumulated heat to provide a faster cleaning (59 minutes if the oven is hot enough, otherwise 1h30).

During and after pyrolysis: Do not attempt to open the door during the entire cycle — it is locked for safety reasons. The surfaces of the oven become much hotter than during normal use. After the cycle ends, a cooling phase occurs during which the oven remains unavailable. Once the oven is completely cooled, simply use a damp cloth to wipe away the white ash, and your oven will be clean.

Important recommendations: Do not use a steam cleaning device. Do not use abrasive cleaning products or hard metal scrapers on the glass door. Keep children away during pyrolysis due to excessive heat. Turn off the oven after pyrolysis by pressing the appropriate button.
