Symptom Problem Solution
The oven does
not cook evenly
The temperature
probe is not
calibrated
If you measure a difference lower or equal of 5 °C, between the real tem-
perature of the cooking chamber and the temperature set, with a cali-
brated temperature probe placed close to the one of the
oven, you can
apply an OFFSET. See the section “BAKERLUX™ Service and User
Menu” to see how to apply the offset. Therefore, if Tset - Tchamber =
+3.1 °C (for instance Tset = 180 °C and Tchamber = 176,9 °C) you should
set -31 in the probe offset to compensate. Thus 0.1 °C equals to 1 in scale
of values.
The oven does
not cook evenly
The temperature
probe is damaged
or the power board
is defected
Measure the resistance of the probe circuit with the multimeter set to
ohm. Do you have 110 Ω at 25 °C (77 °F)?
• If not, replace the damaged temperature probe
• If yes, replace the power board
The cooking
chambers has
spots and
smears on
stain-less steel
and glasses
The cooking
cabinet has
spots of rust on
the stainless
steel
The oven does
not produce
steam
The oven
does not
produce steam
The oven does not
pump in water
Is the tap water open?
• If not, open the tap water
• If yes, do you have power supply to the steam solenoid measured
with the multimeter set to V AC?
- If not, replace the power board
- If yes, is the steam pipe clogged?
• If yes, clean the pipe and check the water quality
• If not, replace the steam solenoid
The control
panel is blank
The oven is in
stand-by mode
When the oven is not running, every 15 minutes it goes into stand-by
mode: the control panel is blank while the LED bar is turned on. To
wake-up the oven touch the control panel screen except on the
physical button.
If for any reason the display does not turn on, press
the power button to reboot the oven manually
The inflow water
hardness is too
high according to
UNOX standart
If the inflow water quality is not in compliance with the technical data
reported in the manual, install the proper water treatment system
The chloride
content
in the inflow
water is too high
according to
UNOX standart
If the inflow water quality is not in compliance with the technical data
reported in the manual, install a UNOX.Pure-RO. Polish the steel
surface with a polish paste
The inflow water
pressure is not
enough
Measure the inflow water pressure with a pressure gauge. Do you
have a value within the range 1.5 < p < 6 bar?
• If not, the water pressure is not in compliance with the UNOX
specification
• If yes, measure the pressure downstream at the output of the
pressure reducer with a pressure gauge. Do you have a pressure
equal to 2,3 bar?
- If not, replace the pressure reducer
- If yes, go on with the troubleshooting
