3 GENERAL
There are eight Benchmark Series 30” models in various
configurations included in the 2014 Bosch built-in wall oven product
line. All models feature Euro-convection (convection fan and ring
element) and TFT full-color displays with touch controls. The lineup
includes models with bottom-hinge doors, right or left side-swing
doors, and two field-assembled combination models, one with a 240V
Microwave Speed Oven and another with a Steam Convection Oven.
Stainless steel is the only finish offered on Benchmark models, which
have control panels and door skins made of grade 439 stainless steel
(magnetic).
The wall ovens are designed to be installed flush with cabinetry.
3.1 Recap of Functional/Technical Changes
Cooling fan: now operates with a variable speed protocol.
Hall effect sensor has been eliminated, and thermal limiter
(HTC) has been added.
Power supply: now located on the control module (relay
board) rather than as a separate component.
Control module: CM controls oven operation only. The user
interface software and operation is separate. The controls are
connected via Dbus.
User interface: TFT-based display with capacitive touch panel
managed by a separate touch control module (TCM).
Daughter board (double ovens only): populated with relays to
operate the lower oven.
Ventilation: air flows up through each door, then back out
over each door as air exits the appliance; some air is pulled
into the unit at the lower vent area under the appliance.
Lighting: Soft lighting is standard on all models. Double oven
lighting is not independent – lights operate concurrently.
Temperature control: now a two-point control for all modes
rather than a PID control for all modes.
Hinges: Models with bottom hinge soft-close doors and
models with side-hinge doors are available.
3.2 Models
The model number structure for the 2014 wall ovens appears below.

3.2.2 Combination Ovens (Sets)
The 2014 combination ovens (sets) are shipped together as individual
components, and are assembled at the customer’s home during
installation.
Although the combination ovens are sold using the combination
model SKU, the service documentation for the sets can be found
linked to the component models rather than the combination
model SKU.For example, the Benchmark series combination with
microwave speed oven is sold as HBLP751UC, but the service
documentation can be found in QuickFinder,linked to its components:
HBLP751UCC (wall oven) and HMC80251UC (microwave speed
oven). There is no service documentation linked to HBLP751UC, but
a cross-reference will appear in QuickFinder when HBLP8751UC is
entered (see Figure 3).
3.3 Data Plate
On bottom hinge models, the data plate reflecting model number and
FD number is located on the left side trim. On side hinge models, the
data plate is located on the side trim, opposite the door hinge.
NOTICE
Be prepared to provide the complete Model Number and FD
number printed on the data plate of the unit when contacting Bosch
Customer Support or Technical Support for assistance.

4.2.3 Setting Temperature Offsets
In some cases, it may be necessary to adjust the oven temperature if
the customer reports that food is consistently under- or over-cooked,
even though the oven is operating normally. Temperature Offsets can
be entered by the customer from the Settings menu to raise or lower
the cavity temperature during operation in Bake, Roast, Convection
Bake, Convection Roast, and Convection Multi-rack modes. The
allowable Offset range is from 0°F to +/- 35°F (or 0°C to +/-19°C).
After accessing the Settings menu, the soft keys beneath the display
are used for navigation and editing.
1. Press Settings to access the Settings menu (from stand-by mode
only)
2. Scroll through the list of menu items using the center soft key, until
8 Temperature Offset is highlighted.
3. Press the soft key labeled Enter to edit the current setting.
4. Press (-) or (+) then enter the numeric value of the offset.
5. Press the soft key labeled Enter to save the current setting.
(Valid offset values are saved when the display changes from edit
mode back to display mode.)
6. Press Oven Clear/Off to exit the Settings menu.
Example: A +25° offset will result in a cavity temperature of 350°
when the cooking temperature is set to 325° for any of the cooking
modes affected by the Offset. Similarly, a -25° offset will result in a
cavity temperature of 300° when the cooking temperature is set to
325°.
For double ovens, a temperature offset may be set for each oven.

The adjusted temperature cannot be less than the minimum allowable
temperature for the cooking mode, nor higher than the maximum for
the cooking mode. See Allowable Operating Range by Cooking Mode
section.
4.3 Self-clean
In a double oven, if Self-clean is running in one cavity, the second
cavity will be disabled until the cycle finishes.
4.4 Cooling Fan
The cooling fan is used to maintain allowable temperatures on internal
components and customer-accessible surfaces.
During Preheat, the fan speed will increase based on cavity
temperature until the final speed is reached at the conclusion of
Preheat. Throughout the Regulate phase of the cooking cycle, the fan
speed will remain constant.
During Self-clean, the cooling fan will run at high speed immediately
after the self-clean cycle begins, regardless of temperature. The fan
will remain at this speed for the entire self-clean cycle.
The cooling fan will run until the cavity temperature is cooler than
491°F (255°C). Once that temperature is reached, the fan will run for
an additional 15 minutes, even if the oven is off. If the cavity
temperature never exceeded 491°F (255°C) during operation, the fan
would not have run at all.
When any of the following errors occur, the cooling fan will operate at
100% until the error is cleared: E101/E201, E002/E302, E303,
E104/E204. See the Error Code Table for more information about
these error codes.

oven out of the cutout approximately ~16 inches, and remove the top
front housing cover completely.
5.4.2 Top Access: Combination Models
To reach the service panel on an HBLP751UCC or HSLP751UCC
oven, follow the steps below...
1. Remove the screws securing the right
and left side trim pieces to the
cabinetry.
2. Carefully slide the combination oven
out of the cutout ~8-9 inches.
3. Remove the locking screw from
the right and left service slides (see
Figure 7).
4. Carefully slide the microwave or
steam oven to the rear ~7 inches; the
service access panel will be
accessible.
If unrestricted access to the top plenum area of the traditional wall
oven, the speed microwave or steam convection oven will need to be
removed.
Note that the length of the conduit/feeder wires which connect the
microwave or steam oven to the oven beneath it are ~5’ long. If there
is a work table nearby, it may not be necessary to disconnect the
feeder wires from the terminal block located in the oven-mounted
junction box on the top of the oven housing.
 CAUTION
When servicing the standard wall oven component of an
HBLP751UC or HSLP751UC combination oven, only the top front
service access panel will be accessible without removing the
microwave oven or steam oven.
If additional access to the top area of the oven is required, the
microwave or steam oven component must be removed. To safely
remove and reinstall the microwave or speed oven, two people
are required.

6 SERVICE AND REPAIR
The HBLP451UC, HBLP651UC, HBLP751UCC and HSLP751UCC
doors are soft-close and have bottom hinges. The HBLP451LUC,
HBLP451RUC, HBLP651LUC and HBLP651RUC doors have side
hinges. The structure and servicing of each door type assembly and
its components are somewhat different. Refer to Section 6.1 for
bottom-hinge door service information and Section 6.2 for side-hinge
door service information.
On all double ovens, the Bosch logo is located on the upper oven
door skin.
6.1 Bottom-Hinge Doors
The serviceable parts of the soft-close door with bottom hinges
include the handle, endcaps, outer door glass/skin (service
assembly), hinges (service kit with one dampen hinge and one spring
hinge), 2-pane glass pack, porcelain-coated door liner, and the
various fasteners.
6.1.1 Removing and Reinstalling the Door
To remove the door…
1. Open door completely.
2. Flip right and left hinge levers back to open, as shown below; be
sure the levers are in the fully open position. (The RH and LH
hinges differ slightly, but operate in the same manner.)
CAUTION
Avoid injury when removing and replacing oven doors.
Be sure oven is cool enough for handling.
Position hinges properly (see Figure 5).
Grasp only by sides, not by the handle.
Do not force door open or closed.
Handle with care–the door weighs approximately 40 lb.
CAUTION
Sheet metal parts often have sharp edges. Avoid injury by
handling these parts with care.
Turn off the electrical power circuit to the oven at the main junction
box before servicing this unit.
For those checks requiring the use of electrical power, exercise
extreme care.
NOTICE
It may be necessary to use a tool, such as a screwdriver, to gently
pry the upper part of the lever away from the housing. Take care to
avoid scratching the porcelain.

6.1.2 Replacing the Hinges
The doors on Bosch Benchmark series ovens are soft-close, and
operate using one dampen hinge and one spring hinge. The hinges
are offered in service kits which include both the RH and LH hinges;
always replace hinges in pairs.
To access the hinges…
1. Remove the door as described in the Removing and Reinstalling
the Door section.
2. With the porcelain-coated door liner up, remove the two screws on
each side of the door liner.
3. Remove the screws along the bottom of the door assembly.
NOTICE
The dampen hinge has a cylinder inside which holds oil that acts as
the dampening fluid and causes the soft-close effect. The oil must be
in the bottom of the cylinder. If the door does not close softly, allow
the hinge time to recover in the vertical position (door closed) for 15-
30 minutes, then re-test door operation. See bulletin packed with
hinge kits for more information.
