4.2 Catalyser

IMPORTANT The 150 W catalyser is situated up on the ceiling of the baking muffle for (optimised air purification). As the grease vapours require adequate oxygen for complete incineration, air is drawn in by the cooling fan.

Heat the cat. honeycomb for approx. 1 hour to eliminate any new odours.

After an adequately long heating-up time, the smoke rises to the upperside of the baking muffle, penetrates the grille and is heated on contact with the heating element. The catalyser accelerates incineration. From 350 °C the heated ceramic honeycomb results in an optimum reaction which converts the smoke into an almost odourless and colourless mixture. The cooling fan blows this mixture through the ventilation grille under the door.

When the appliance has been switched OFF, the catalyser continues heating for approx. another 45 min. The K 14 relay is re-actuated over this time.

NOTE Catalyser from FD 8207 Catalyser up to FD 8206

Despite the electrically heated catalyser, there are still occasional complaints about odours.

Predominantly these complaints affect appliances up to FD 8206 When servicing the appliance, replace this catalyser with the new, more powerful catalyser (fig. on left). On account of the larger geometrical surface of the new cat. honeycomb, it was possible to further improve the air purification. Spare-part no. 489346

As the cat. heater and housing have not been changed, it is adequate to replace just the cat. honeycomb.

5 FUNCTIONS 5.1.1 Heating-up times

5.1 Rapid heating up (super quick circuit)

The super quick circuit is active for hot air operating mode only. In addition to the ring heating element the bottom heat heating element is connected. Bottom heat is active for as long as the temp. difference between required and actual temp. is greater than 50 K. General: The heating-up times are dependent on the mains voltage. In top/bottom heat mode the time is extended on account of the convection heat and the lower heating element power. When heating up in any operating mode, a temperature increase (overshoot) of approx. 25 K is required in order to compensate for the temperature loss when putting in food (open door, cold food).

5.3 Cooling fan on 5.4 Pyrolysis

Cooling fan is two-stage via winding tap. The pyrolysis feature heats vegetable and organic matter to approx. 485 °C. As a result of thermal decomposition, solid, liquid and gaseous substances are formed. The evaporating substances are conveyed out through the cooling fan via the catalyser. Only ash remains. When the appliance has cooled down, wipe out the ash with a damp cloth.

Oven mode: When the appliance is switched on (temperature sector min. at “Light” position), the cooling fan runs at setting 1 and is actuated at setting 2 depending on the housing temperature (NTC on power electronics module) or the oven temperature (PT1000). In normal mode setting two does not occur. Implementation:

Take all accessories out of the cooking compartment. Remove coarse dirt beforehand, manually clean the door seal, inside of door and glass pane.

5.5 Locking motor 5.6 Catalysis

Self-cleaning aid: The locking motor is activated at a muffle temperature > 316 °C as well as the pyrolysis operating mode (lock). While pyrolysis is running, the key symbol flashes on the display. In the end position the key is displayed statically. Oven unlocks again at 304 °C after pyrolysis has run (unlock).

In this operating mode the soiling on the catalytic inner plates (rear panel and side panels) are incinerated at temperatures of approx. 300 °C. The enamel feels rough, similar to a fine sand paper. For test purposes the locking motor may be activated even at room

temperature by jumpering the reset contact on the electronics module (next to ST15) as well as in the Service programme Pos.06.04. Any intermediate position is possible. At the end of the Service program the motor moves to the end position.

Large-surface and thick soiling caused by sugar and acid leave stains on the brightly coated plates, however their function is not affected. It is not possible to cover the entire baking muffle with these plates. Therefore, before selecting the 300 °C cleaning aid, manually clean the floor, ceiling, door and pane prior to catalysis. The grease filter as well as the accessories must be taken out of the cooking compartment.

If areas have burnt-in dirt, it is difficult to clean these. In this case only a standard oven cleaner (e.g. K2R) will help, however the cleaner must not come into contact with the anodised parts. Cleaner must be wiped off immediately to prevent discoloration. Entry: Rotate the selector and temperature switch one setting to the left. Set cleaning time via Plus/Minus button. (Setting range 1–3 hours in minute steps). Increase suggested time 1:30 hours to recommended 3 hours. Acknowledge with “S” button.

7.3 Time differs Rectifying the fault: ► ► ►

►

Remove the appliance. If the clock is extremely slow or fast on account of large mains frequency fluctuations, Parameter “P04” (parameter table) for time detection can be switched in the Service programme test step 08 from combined mains frequency detection/quartz operation to just quartz operation. The electronics module does not have a technical defect.

Remove the rear panel. Push bottom heat heating element forwards until it touches a stop. Insulate the heating element connections with sleeves.

7.4 Furniture damage 7.6 Baking sheets jamming

Veneers or plastic coatings on installed furniture must be processed with heat-resistant adhesive. If the requirements are not met, the veneer will become detached.

7.6.1 Catalysis appliances

When inserting the catalytic side plates, ensure that the guide grilles (at the front) are fitted under the catalytic side panels.

The oven conforms to the currently valid European standard EN 60335. A temperature increase of max. 65 K at room temperature is permitted. This means that at a room temperature of 20 °C to 25 °C the furniture may have a temperature of 85 °C to 90 °C.

7.5 Appliance is heating although OFF

Cause of fault: Up to FD 7712 the bottom heat heating element could slip backwards and touch the rear panel of the appliance with the N-connection. When the appliance has been switched OFF, the catalyser continues heating for approx. 45 min. The K 14 relay is still actuated over this time and supplies the BH with voltage due to the resulting earth fault. An installed residual-current-operated circuit-breaker would trip. Fault description: Does not apply to US or CH versions.

7.9 Three “- - -” dashes on the display 7.6.2 Pyrolysis appliances

For functional reasons the enamelled baking sheets run along the side panels which are also enamelled. This results in slight wear, but not enamel damage.

7.9.1 Low voltage

Fault description: The baking sheets are bent on the right and left. Material must not project at the front or back, if required rework with emery paper.

Three dashes are displayed and an alarm sounds. Cause of fault:

Mains voltage < 195 VAC

7.7 Baking sheet twisted Rectifying the fault: Check mains voltage and connections under load. The cold food (frozen food) must not be placed on the preheated

baking sheet but on the grill shelf. Insert the grill pan into the shelf position underneath to catch the liquid.

7.9.2 Power failure

Fault description:

7.8 Display of varying brightness Three dashes are displayed and an alarm sounds. Cause of fault:

If the mains voltage fails while the appliance is on, oven operation does not automatically continue when the mains voltage is restored.

Rectifying the fault: The appliance must be switched off and on again with the temperature switch. Note:

Fault description: If power failures > 2 hours, the time is no longer buffered. When the mains voltage is restored, the time must be reset. Suggested time on the display h/min 08:00, the same time when the appliance is switched on for the first time.

The light segments lose brightness and become illegible, especially those segments which are always or frequently on, e.g. time display. Cause of fault: The display is subject to an ageing process. Rectifying the fault: Replace the display, see point 6.2.

7.9.3 Vacation safety device:

Three dashes are displayed and an alarm sounds. Each heating process is terminated after 12 hours, provided no operation has occurred during that time. Deactivation: Switch OFF appliance. This function is off in timer mode. 7.9.4 Display significantly darker

Fault description: Display is significantly darker than in normal mode even though the mains voltage is in working order. Appliance does not heat up Cause of fault: Temperature on the display is > 120 °C Ribbon cable to the display has contact problems. Display NTC sensor defective or bad soldered joint. Rectifying the fault: Resolder sensor, if required replace display or cable. Procedure: See point 6.2
