NOTE: The WARNING and IMPORTANT instructions appearing in this manual are not meant to cover all
possible conditions and situations that may occur. It must be understood that common sense, caution, and
carefulness are factors which cannot be built into these washers. These factors MUST BE supplied by the
person(s) installing, maintaining, or operating the washer.
Always contact the distributor, service agent, or the manufacturer about any problems or conditions you do not
understand.
Failure to install, maintain, and/or operate this machine according to the manufacturer's
instructions may result in conditions which can produce bodily injury and/or property
damage.
To determine control version, apply power to machine.
Control will display version of control (i.e., 1.15).
Language on Display (Version 1.15 and
later ONLY)
To set a different language on the WE-8 display:
1. Turn key from RUN to PROGRAM.
2. Press “Auxiliary”, “2” and “9” to enter set-up
mode.
3. English will display. Press “Advance” until
desired language displays (French, Italian,
Spanish and German).
4. Press “Enter” keypad.
5. Press “Enter” to advance through set-up mode.
6. Wait until information is saved.
7. Turn key from PROGRAM to RUN.
8. Display will read language chosen for all cycles.
Setup of the Chemical Hold Feature
(Version 1.11 and later ONLY)
At power up, verify that model is at least
version 1.11. Refer to version of Control Section.
Earlier versions do not have this chemical hold
feature.
Insert key into key switch and turn to Program.
NOTE: If chemical hold is off, then supplies 4
through 9 are controlled exactly like supplies 1
through 3. A switch closure/opening between pins 1
and 4 of the COIN header on the output board will
have no effect.
Program Storing Mode
The WE-8 control is capable of 99 total cycles. One
cycle contains 1 or more steps.
One step is a function of the wash program
(example: heat).
Choose between the following functions:
Fill:To fill the machine with water.
Wash: Wash action of the machine.
Supply:To add detergent to the wash (liquid or
powder).
Cooldown: Cool to programmed temperature
Heat: To heat the water.
Soak: The wash will be soaked for a
programmed time and a programmed
temperature.
Aux: A relay contact will close for a
programmed time.
Spin: To spin the machine for a programmed
time and RPM.
Drain:To drain the water from the machine.
Push the Auxiliary key, the 2 key, and the 9 key
in succession to enter System Program Mode.
Push the Start key 10 times to arrive at the
Chemical hold choice.
Push the Add Cycle/Advance key to toggle the
Chemical hold feature either Yes (on) or No (off).
Push the Start key twice to save changes and exit
System Program Mode.
Turn key switch to Run.
NOTE: If chemical hold is on, then a switch
closure/opening between pins 1 and 4 of the COIN
header on the output board will control supplies 4
through 9. A closure will turn the programmed
supply/ies on and count down the time for the
supply to be on. An opening will turn the
programmed supply/ies off and halt the time for
the supply to be on.
temperature of water coming in to the machine during
a fill step. This does not apply to “Aux Fill” step. The
control will mix the hot and cold water inlet to the
temperature programmed in the fill function. To fill in
the temperature, select the water inlet type and the
water level. Press the “Heat” button and the control
will ask the temperature. In this way the water inlet
type selected is of no use because the control will mix
between the cold and hot water inlet to reach the
temperature.
Example: Fill to low level and 95°F (step time limit:
5 minutes 30 seconds).
Enter desired temperature for load to
cool down to. Three digits must be used
for temperature. If Fahrenheit, the valid
temperature range is 80° – 200°F. If
Celcius, valid temperature range is
25° – 90°C (example: 95°F).

This function drains the water.
If you have 2 drains, select which drain has to be
opened.
NOTE: With the WE-8 control, it is NOT necessary
to program a drain step before spin. The spin step
incorporates the balancing routine and draining
before beginning high speed spin (as a sub part of
the spin step). A programmed drain step will be
skipped if spin step is programmed immediately
after it.
The step is deleted. Press the “Advance” button to end
cycle 51 and press “Enter” 2 times to save the settings.

flows in the motor this function stops the
increase in frequency until the overload
current reduces to prevent the inverter
from resulting in overcurrent shut-off.
When the overload current has reduces
