Questions

Uneven baking

Solutions

Check the breakers on the front panel.
Check the breaker of the building.
If the oven has already functioned, check if the
doors are tightly closed.
Check the overload relays located in the control
compartment. If anyone of these is disengaged,
call for a qualified technician.
Make sure that the grills do not obstruct the
airflow. Do not use foil on grills.
The oven temperature is too high.
For best result, cooking temperature should be
around 3500 F to 3750 F.
To put in or take out bread pans, open the door
2"(5 cm) and wait 5 secondes before opening
the door completely.
Check the oven temperature by using an oven
thermometer and make sure that it is even to the
thermostat setting.
Check if the baking time is longer than usual
and if the oven is baking much more on the
bottom. If it is the case, one element may be
burned.
If the oven is baking too much on the sides, it is
possible that the fan is not cycling properly.
(Check if the motor turns 2.5 minutes in a
direction, stops 30 seconds and starts for 2.5
minutes in the opposite direction).
The doors should not be opened unnecessarily to
conserve the heat.
Find out leak of heat and correct it.

A9

The steam works in the oven but the light
inside the steam button does not lite.
If steam device does not work properly.

Replace the light bulb inside the push button.

The oven must have been heating for at least
half an hour before you use steam system. If
not, water will appear at the bottom of the oven.
Check if the water supply valve (of the
building) is open.
Check if the water needle valve (of the oven) is
open one-eighth of a turn. Just close it and open
it one-eighth of a turn, maximum.
Check the solenoid valve.
Check the preset steam timer in the back
control box.
Be sure to inject steam while the fan is running.
The steam button light should lite during the
steam injection.

Oven maintenance and cleaning

MAINTENANCE OF THE OVEN

• It is recommended to use a water filter and to clean or replace it regularly to avoid

accumulation of minerals inside the unit.
