1. INTRODUCTION
1.1 - PURPOSE OF THIS MANUAL
The purpose of this Manual is to provide a general outline of the methods of accessing the
various versions of ACCESS ovens.
2 - ELECTRIC / ELECTRONIC OVENS
2.1 - DISMANTLING BUILT-IN OVENS
IMPORTANT: Always disconnect the appliance from the power socket before accessing
internal parts.
Access to certain components is possible by pulling the oven partially out of the compartment.
With the oven partially pulled out, the service engineer can access the components of the
front panel and the electronic control unit; for access to the other components located in the
rear section, it is necessary to remove the built-in oven completely from its compartment.
To remove the oven:
1. Remove the 4 screws, located at the front of the front panel, which secure the appliance to
the compartment (see Fig. 1 and 2)
Fig. 1 Fig. 2
2. Remove the oven
(Fig. 3).
Fig. 3
SOI 04.04 FV 6/50 599 35 96-40
2.2. DISCONNECTING FROM THE POWER SUPPLY
IMPORTANT: Before accessing any of the components inside the oven, it is essential to
disconnect the oven from the power supply by removing the plug from the power socket or by
turning the main switch on the domestic circuit (if featured) to "OFF".
2.3 - REMOVING THE CONTROL PANEL
In order to remove the control panel, first remove the rubber knob caps and, where featured,
the knobs.
1. Open the oven door.
2. Slide off the rubber knob caps (and the control knobs).
3. Remove the two screws from the lower section of the front panel (see Fig. 4 and 5).
4. Slide the control panel upwards and release from the upper retaining tabs.

In order to remove the convection heating element, first remove the rear panel. Then:
1. From the rear section of the oven, detach the connector wires and carefully mark their
positions (see fig. 6, pos. 6).
Remove the two screws (located inside the oven) (see fig. 10, pos).
Proceed as follows to remove the convection fan:
1 - Remove the central screw while holding the fan blades in position.
IMPORTANT: The screw is threaded in the opposite direction, i.e. must be turned counter-
clockwise to tighten)
2.4.6 - REMOVING THE LAMP-HOLDER
Remove the rear panel, then proceed as follows to remove the lamp-holder:
1 - Using a screwdriver with a 3mm tip, detach the connector wires.
