discarded, remove the door to the washing
compartment.
8. Do not reach into the washer if the wash drum is
moving.
9. Do not install or store the washer where it will be
exposed to water and/or weather.
10. Do not tamper with the controls.
11. Do not repair or replace any part of the washer, or
attempt any servicing unless specifically
recommended in the user-maintenance
instructions or in published user-repair
instructions that the user understands and has the
skills to carry out.
12. To reduce the risk of an electric shock or fire, DO
NOT use an extension cord or an adapter to
connect the washer to the electrical power source.
13. Use washer only for its intended purpose,
washing textiles.
14. ALWAYS disconnect the washer from electrical
supply before attempting any service. Disconnect
the power cord by grasping the plug, not the cord.

Introduction
The “B” electronic control is composed of the
electronic control unit and the control fuse board with
wiring harness. Only an authorized person should look
inside the machine. First TURN OFF POWER, open
lid and remove any cover present. Make sure door lock
circuit has fully discharged. The door unlock capacitor
can retain high electrical charge, even when the
machine’s electrical inputs are disconnected, until it
has discharged. Some machines are equipped with an
“amber” indicator light facing upward in the control
compartment. If this is on, wait until it goes off
(indicating when high voltage in the door lock circuit
has discharged).
Electronic Control Unit
This portion of the control contains the “intelligence” –
the micro-controller and the miscellaneous components
on the printed circuit (PC) board. The board has a
metal cover, which MUST be in place at all times
during machine operation. Operation of the machine
without this cover installed will void the warranty.
The control unit monitors and responds to input, gives
information about the status of the washer and
monitors and responds to inputs from the user
interface (keypad). The control provides signals to the
control output unit, which in turn operates the
components that control the machine functions. This is
located behind the machine control panel.
This portion of the control contains the power supply
for the control unit, and also the switching devices
which power the components in the machine, all of
which are on the output PC board. The switching
devices are controlled by the control unit, and are solid
state.
Harnessing
Wiring harnesses are modular – harnesses common to
various configurations are similar, while those specific
to a certain configuration can be added. There are
harnesses for inputs to the control unit, for outputs
from the control power/output unit to the machine
components, and for the main incoming power to the
control power/output unit.
The nameplate is located at the rear of the machine and
inside door. Always provide the machine’s serial
number and model number when ordering parts or
when seeking technical assistance.

galvanic corrosion when salty or acidic solutions
are present.
●Do not allow salty or acidic solutions to
evaporate and dry on stainless steel. Wipe clean
of any residues.
●Do not leave sanitizers or sterilizing solutions on
stainless steel equipment for prolonged periods
of time.
●When an external chemical supply is used, ensure
no siphoning of chemicals occurs when the
washer-extractor is not in use. Highly
concentrated chemicals can cause severe damage
to stainless steel and other components with the
machine. Damage of this kind is not covered by
the manufacturer’s warranty. Locate the pump
below the washer-extractor’s injection point to
prevent siphoning of chemicals into the machine.
●If the stainless steel appears to be rusting, the
source of the rust may actually be a foreign piece
of iron or steel part not made of stainless steel,
such as a nail or screw contacting the stainless
steel surface. Tip: Paint all carbon steel parts with
a heavy protective coating. Stainless steel
fasteners should be used whenever possible.
