SAFETY
1.1
General hazards
m
Don’t use the dishwasher until it is completely installed. When
opening the door on an uninstalled dishwasher, carefully open
the door while supporting the rear of the unit. Failure to follow this
warning can cause the dishwasher to tip over and result in
serious injury.
In some conditions, hydrogen gas can form in a hot water system
that has not been used for weeks. Hydrogen gas is explosive.
Before filling a dishwasher from a system that has been off for
weeks, run the water from a nearby faucet in a well ventilated
area until there is no sound or evidence of gas.
Temperatures required for soldering and sweating will damage
the dishwasher’s base and water inlet valve. If plumbing lines are
to be soldered or sweated, keep the heat source at least 6 inches
(152.4 mm) away from the dishwasher’s base and water inlet
valve.
Removing any cover or pulling the dishwasher from the cabinet
can expose hot water connections, electrical power and sharp
edges or points. Handle with care. Always wear gloves and safety
glasses.
1.2
Electrical shock / fire hazards
c h
Don’t allow electrical and water supply lines to touch. Don’t work
on an energized circuit. Doing so could result in serious injury or
death. Only qualified electricians should perform electrical work.
Don’t attempt any work on the dishwasher electric supply circuit
until you are certain the circuit is de-energized.
Make sure electrical work is properly installed. There should be
no loose electrical connections. Ensure all electrical connections
are properly made.
702_58300000130262_ara_en_b
The customer has the responsibility of ensuring that the
dishwasher electrical installation is in compliance with all national
and local electrical codes and ordinances. The dishwasher is
designed for an electrical supply of 120VAC, 60 Hz, connected to
a dishwasher-dedicated, properly grounded electrical circuit with
a fuse or breaker rated for 15 amps. Electrical supply conductors
shall be a minimum #14 AWG copper only wire rated at 75°C
(167°F) or higher.
This appliance must be connected to a grounded metal,
permanent wiring system, or an equipment-grounding conductor
must be run with the circuit conductors and connected to the
equipment-grounding terminal or lead on the appliance. Don’t use
extension cords.
1.3
Plumbing / scalding hazards
m
Don’t perform any work on a charged hot water line. Serious
injury could result. Only qualified plumbers should perform
plumbing work. Don’t attempt any work on the dishwasher hot
water supply plumbing until you are certain the hot water supply
is shut off.
Don’t over tighten the 90° elbow. Doing so may damage the
water inlet valve and cause a water leak. Temperatures required
for soldering and sweating will damage the dishwasher’s water
inlet valve. If plumbing lines are to be soldered or sweated, keep
the heat source at least 6 inches (152.4 mm) away from the
dishwasher’s water inlet valve.
Check local plumbing codes for approved plumbing procedures
and accessories. All plumbing should be done in accordance with
national and local codes.
These instructions depict an installation method for stainless steel
braided hose or PEX hot water supply lines. If using copper
tubing or other material for water supply, defer to a licensed
plumber for proper installation.

INSTALLATION
2.1
Pre-Install checklist
□ Unpack unit. Retain packing material until installation is
successful.
Remove packing material from inside the
dishwasher.
□ Inspect parts to ensure you have all the necessary materials.
□ Flush household hot water supply for at least two minutes.
□ Measure the enclosure area. The opening must be at least
34" (87 cm) high and 23-5/8" (60-61 cm) wide.
□ The opening must be close enough to the sink for water line
and drain hose plumbing access.
□ Unit must be installed close enough to the sink so that drain
hose length does not exceed 92" (234 cm) and a high loop is
raised at least 20" (51 cm) above the floor.
□ Wooden openings must be sanded smooth and metal
openings must be covered by a protective gasket.
□ Is your water heater set at 120°F (49°C) and does water
pressure measure 15-145 psi (1-10 bar)?
□ If installing in a corner, the dishwasher door must clear
cabinet hardware.
□ Determine mounting method based on dishwasher model and
countertop type, whether top or side mount.
2.2
Alignment
Carefully place dishwasher on its back to pre-adjust all three feet
-- turn feet clockwise to raise or counter-clockwise to lower.
Maximum height with feet fully extended is 34.5”.
Place
dishwasher upright, then level side to side and front to back.
When done, insert leg leveler locking screw in back foot.
2.3
Electrical connection
Install according to national and local codes.
Carefully place dishwasher on its back to make electrical
connections to the terminal block. Turn power off at the fuse box.
Extend power cord approximately 21” from the left side of the
opening, and 30” from the back wall, making sure the cord
doesn’t contact any moving parts.
Strip outer casing of electrical wire to expose 2.5" - 3" (65 - 76
mm) of inner wires, then strip 1/2" (13 mm) casing from each
wire. If plugging the dishwasher into an outlet, contact customer
service to order approved power cord accessory kit
(SGZPC001UC). Insert cord through a strain relief (not included)
and install to strain relief plate. Attach wires to terminal block
(black – L (hot), white – N (neutral) & green – G (ground).
Unscrew terminal screws, but don’t loosen or remove them as
they may become damaged. Attach wires snugly, but don’t
overtighten.
Regardless of countertop surface, mounting brackets are
attached on the side of dishwashers. They are screwed into
screw bosses on the side dishwasher frame, then into the
cabinetry.

Unlike with traditional dishwashers, do NOT disconnect drain
pumps when using sales demo programs. Dishwasher controls
run safety checks – if drain pumps or heat pumps are
disconnected, dishwashers will NOT run.
No disconnections are needed – just add one (1) gallon of water
(with bacteria stat) to dishwasher tanks. Heat pumps will run and
lights will light when program buttons are pushed. Drain pumps
do not run. It’s not necessary to plug drain hoses, but it’s a good
practice to prevent any possible water leakage.

COMPONENTS
4.1
Tank with base and sump
4.1.1
Tank, base and sump assembly
The tank, base and sump are welded together and aren’t
available as a service part. If plastic cable holders, part holders
and screw holes are damaged or stripped, the entire dishwasher
must be replaced.
Center rear

Right rear
adjusting foot
4.2
Center rear foot set screw hole
Heated circulation pump (heat pump)
There’s no flow-through heater, flow switch or Hi-Limit cutout –
the circulation pump has a flow-through heated cylinder. The 120
VAC, 1200W heater cylinder provides more heating surface area
and heats water slightly more quickly than traditional flow-through
heating elements (~ 2ºF/minute). The circulation pump (portion)
has a 3-pole BLDC motor controlled by the power (control)
module. The dishwasher won’t run if the heat pump is
disconnected or disabled.
Pump suspension strap
4.1.2
Rear leveling foot
The rear leveling foot can’t be adjusted from the front – the rear
foot is the same as front feet and is adjusted the same way. The
base has provision for two rear feet in the rear corners, but the
center foot factory mounting should be used.
Factory feet positions have provisions for set screws (in
installation parts bag). Outside rear positions don’t have set
screw positions and shouldn’t be used.

4.5
Water inlet / condensation system
Unlike prior dishwashers, Ascenta dishwashers use a common
water inlet and condensation system. Instead of feeding water
into the bottom of the tank, dishwashers fill into the left side of the
tank. Instead of condensation exiting from the right side of the
tank, it exits the left side of the tank through the water inlet.
There are three hoses connected to the water inlet system, the
water inlet hose (from the water inlet valve), condensation
(breather) hose and internal drain hose. The internal drain hose
has a factory made high loop (~ 15” above the floor) and
connects to the external customer drain hose.
Ascenta dishwashers use a time-fill.
702_58300000130262_ara_en_b

The spring has loops at both ends and connects to a long slot in
the base. Springs are color coded for specific tensions.
4.7
Water inlet valve
Ascenta dishwashers use standard horizontal coil water inlet
valve with (Rast 5) connector. The valve nestles in the left side of
the base on base tabs and is held into place with two screws.
Door spring
The door spring mechanism is simple, requiring no pulleys or
cords. A long narrow spring connects between the base and
hinge lever (using a plastic connector) to provide proper tension.

4.8
Door latch
4.10
The door latch is mounted on top of the tank and doesn’t contain
a microswitch. It uses a Hall-effect sensor in the door to sense
when the door is open or closed. The Hall-effect sensor is held
by two T-10 Torx screws. The door latch is held by one T-20
Torx screw and two tank tabs.
Door
latch
Drain hose
Ascenta dishwashers use a two-hose (internal / external) drain
hose system.
A customer (external) drain hose (during
installation) is connected to the internal drain hose, with the 90º
elbow pointing toward the customer drain. The external drain
hose connects directly to the customer drain system without an
adapter.

hose connects to the sump and the other hoses connect to the
water inlet / condensation system.
Inlet hose
Ascenta dishwashers have two control modules, a display
module (with display, lights & buttons) in the fascia (control) panel
and a power module in the base on the right side. The power
module controls the BLDC drain pump and heat pump.

Digital and LED fault code displays
6.1.4
Digital error codes only show on SHE5AM dishwashers with
digital displays. SHE4AM / SHX3AM dishwashers show the
same LED display for many error codes, so it’s not possible to
determine which specific error code occurred.
For example, LED display
shows for any power module
failure causing digital error codes E:01, E:02, E:03 and E:05.

Customer fault codes (SHE5AM digital display only)
SHE5AM dishwashers have fault codes seen by customers.
Viewing the fault code (Display Failure Memory) chart, the last
two columns (under “Customer Failure display”) show fault codes
seen by customers in the digital display. The first two columns
(under “Customer Service Failure display”) show fault codes seen
in the fault code program. Fault code displays are identical – the
only difference being some service fault codes (e.g. E:08, E:16)
can’t be seen by customers.

Clearing fault codes
To clear fault codes, run the customer service test program.

Troubleshooting
6.3.3
6.3.1
Protection of heater if there’s no water
There is a single 3-pin connector, connecting to the 3-pole BLDC
pump motor.
Two NTC’s protect the heater. Both NTC’s are checked by the
control – if they overheat, the control shuts down the dishwasher
(E:08 fault code). The dishwasher shuts down if only one NTC
returns a signal (E:12 fault code) or if they show different values
(E:11 fault code).
6.3.2
Drain pump
Resistances as follows:
1 – 2: 89.6 Ω (@ 68 ºF)
2 – 3: 89.6 Ω (@ 68 ºF)
3 – 1: 89.6 Ω (@ 68 ºF)
Heat pump terminal measurements
There are two connectors, 7-pin and 3-pin.
6.3.2.1 7-pin connector (heater / NTC’s / pump ground)
The 7-pin connector connects to the heat pump heater, NTC’s
and ground.
