Possible Causes and Suggested Solutions
Turn the oven off at the circuit breaker and wait five minutes.
Turn breaker back on. The oven should reset itself and will be
operable.
Check circuit breaker or fuse box to your house. Make sure
there is proper electrical power to the oven. Be sure oven
temperature has been selected.
The water tank is empty or operations are locked due to the
descaling process. Fill the water tank and continue the des-
caling process.
The appliance has not cooled sufficiently. Allow the appliance
to cool and switch the operating mode on again.
The power supply has been disconnected or the appliance
has been switched off during the descaling process. Once
the appliance is switched on again, rinse it twice.
The oven thermostat needs adjustment. See "Oven Tempera-
ture Offset" under "Adjust Basic Settings".
Replace or reinsert the light bulb if loose or burned out.
Touching the bulb with fingers may cause the bulb to burn
out.
Check for obstruction in oven door. Check to see if hinge is
bent.
There may be soil build-up around the lens cover. Wipe lens
cover area with a clean dry towel prior to attempting to
remove the lens cover.
Allow the oven to cool before running self-clean. Always wipe
out loose soils or heavy spillovers before running self-clean. If
oven is badly soiled, set oven for the maximum self-clean
time.
Make sure there is electrical power to oven.
This is a fault code. Follow the instructions in the display. If
the code remains or there are no instructions in the display,
press INFO to display more information (if applicable) and to
turn off the beep. If the code is still displayed, write down the
fault code number, turn off the oven, and call Service.
This is normal with a new oven and will disappear after a few
uses. Operating the self-clean cycle also "burns-off" the smell
more quickly.
Be sure that pad is clean. Touch the center of the touchpad.
Use the flat part of your finger.
On some models, the convection fan runs while the oven is
preheating for the bake mode. This is normal.
It is normal to see or feel steam or warm air escaping from
the oven vent. Do not block the vent.
This is normal. The cooling fan will continue to run, even after
the oven has been turned off, until the oven has cooled suffi-
ciently.
The soft-close door hinges contain a damping fluid that is
affected by temperature. If the oven is in a cold environment,
the door will close slower than it will in a warmer environment.
A warmer than normal environment, such as when cooking,
may cause the door to close slightly faster.
The set water hardness range is too low. Check the set water
hardness range and adjust if necessary. Carry out descaling.
