Rotary Knob; Water Level Control Electrodes; Capillary Thermostat; Terminals - Electrolux VARIO STEAM S33-E Operating & Installation Instructions Manual

ROTARY KNOB

Rotary knobs are fitted at the selection switch for cooking
temperature and pressure as well as at the switch for
setting the cooking time.
Removal
Prise the cap of the operating knob off with a knife. Take
away the nut in the center of the knob. Pull the knob off its
spindle.
Installation
Turn the spindle counter-clockwise as far as the stop. Put
the knob on and turn the arrow to the scale graduation on
the far left. Tighten the nut in the center of the knob and
replace the cap.
WATER LEVEL CONTROL ELECTRODES (NE)
(B1/B2)
Faults in the water control system in the water container
may be due to malfunctioning electrodes. The electrodes
must be descaled periodically and checked for corrosion
damage. The two level electrodes are identical, but are
installed to different depths. The electrodes are located at
the very front at the top of the cooking compartment.
Removal
Remove the cover in accordance with §5. Unscrew the
electrical connection. Take off the union nut. Pull the
electrode upwards and out.
Installation
Clean the pipe holder well. Further procedure as
described under "Removal" but in the reverse order.
CAPILLARY TUBE THERMOSTAT (TW) (B4)
The thermostat regulates the maximum water temperature
(80°C) in the water container while the appliance is
heating up. It is located above the cooking compartment in
the front part. The sensor is pushed into a tube that dips
into the water container.
If the water container temperature indicates a larger
deviation (more than 80 ± 10°C) after preheating, the
thermostat must be replaced.
Removal
Remove the cover in accordance with §5. Twist the
thermostat to a position that will allow the attachment
screws on the two plastic tabs to be removed with a
screwdriver. When the tabs are removed, the thermostat
switch is free. Take out the split pin that is installed at 90°
to the capillary tube sensor jacket pipe and fixes a rod-
shaped holder for the sensor. Pull out the holder and
sensor upwards. The jacket pipe is attached with a union
nut and a seal to a spigot of the cooking compartment.
Installation
If the jacket tube is being removed, make sure during
installation that the seal is in perfect condition. The sensor
is inserted dry into the tube as far as the bottom.

TERMINALS (X)
Removal and installation
The
compartment and is accessible from above after the cover
has been removed. Normal terminals are only engaged
with the strip and can be flipped off with a screwdriver.
The conductor terminal is also attached by a central screw
that has to be released during disassembly.
CONTROL FUSE (F1-2)
Removal and installation
The fuse (2 may also be fitted) for the control pcb is
located on the terminal strip. Remove the cover in
accordance with §5. Open the cover of the fuse terminal
by lifting it at one side. Take out the fuse sideways or
insert a new one. The fuse is loose in the holder. Reclose
the terminal cover.
CONTACTORS (K1-2)
Removal: Remove the cover in accordance with §5.
Terminal strip and contactors are fitted to a common
bracket. Pull the cable connections off the contactor. Flip it
out of its spring catch in the middle of the foot with a
screwdriver and take it out on one side at an angle.
Installation: The contactor is simply locked onto the rail
with a spring attachment. Connect the cables. Continue to
install in the reverse order to the disassembly instructions.
RELAY (K3)
The purpose of the relay is to transmit the signal from the
door switch and to prevent the heating from working when
the lock has not been closed.
Removal
Remove the cover in accordance with §5. The relay is
located on the terminal strip next to the contactors.
Remove the upper active part from the socket. If the
socket also has to be removed: disconnect the electrical
cables, flip it out of its spring catch in the middle of the foot
with a screwdriver and take it out on one side at an angle.
INTERFERENCE FILTER (Z1)
The filter is located behind the control pcb on the
horizontal sheetmetal and serves to prevent interference
in the mains supply from affecting the electronics in the
appliance.
