6Synthetic wash
Long main wash, 3 rinses and short spin.
7Short spin

Gentle action and high water level.
9Pumping out

WM 90
PUSH BUTTONS
Main switch
Interupts the line (L1) and neutral connections.
No Spin
Omits the intermediate and the terminall spin. In programs 1-3 is
the water pumped out after the last rinse. In program 5, 6 and 8
the machine stops with the last rinse water in the cylinder.
Door opening
The door can be opened when the power is turned on, the water is
pumped out, and the timer is in one of the two positions, which are
marked with a dot.
Economy
Extends the main wash by 22 minutes.
Half load button
Omits the intermediate spin and two rinses in program 1-3. In
program 5 and 6 reduces one rinse.
800-button
Reduces spin speed to 800 rpm. With the button up, spin speed is
1000rpm.
Rinse level
In position you get high rinse level. In position you get
normal rinse level.

ELECTRICAL FUNCTIONS
Level controlled pumping out
Pumping out is made to the return level for the normal level, plus
additional 30 seconds, max. 1,5 minutes
Advantages:
*By installations with reduced drain flow, the pumping out is
prolonged to prevent the machine to go on washing with "old"
water" left in the machine.
* By normal drain flow there will be no noise by pumping of mixture
water-air.
Temperature block
In the wool program, the temperature Stop step has been maximized to 24
minutes. This means that if the temperature by mistake is set on, say 90°C,
the temperature still will not be higher than good 40°C (can vary a little
depending on the temperature of incoming water, the size of the load etc.).
In Whites wash/Cotton programs and in the synthetic programs the time for
the temperature stop is maximized to 80 min. This prevents among other
things the water to cook by broken thermostat (if the capillary tube is
broken) or that the machine goes on "for ever" by broken heater.
Out-of-balance-control by spin
The spin sequence consists of a short spin-up to 500 rpm, a so called
"peak", distribution and a longer spin. A tacho generator, placed on the
motor, measures the speed difference between the ”up-hill and down-hill”
before the spin. The greater the diffenrence, the greater the un-balance. If
the unbalance is too large, the spin is interrupted and the machine
distributes the washing and tries again.
By the peak maximal 9 start attempts are made,where the unbalance must
be below 0,8 kg for spin-up. If this is failed, additional max. 6 start attempts
are made with max 1,2 kg unbalance permitted.lf the unbalance is still too
high, machine will pass the spin step.
If the machine has made the ”peak”, the washing is distributed again,
start attempts to spin are made. Hereby max. 9 start attempts are made
with max. 0,7 kg permitted unbalance to reach 1000 rpm. After that further 6
start attempts are made on unbalance level 0,7 and 1,2 kg: If the unbalance
is less than 0,7 kg, the spin is made by 1000 rpm, if it is 0,7-1,2, the spin is
by 800 rpm.
If the unbalance is still too high, the machine passes the spin step.

ELECTRICAL COMPONENTS
1Timer
The timer has an electro-mechanical unit and an separate electronic unit.
The electronic unit controls the motor, the timer motor and some of the
program features.
The mechanical unit among others controls inlet valves, outlet pump and
heater.
2Thermostat
The temperature can be set stepless 0-90° C.
3Motor
The motor is an universal motor The rotation speed is stepless controlled
by a tacho generator on the motor which measures the rotation speed.
Maximal speed is 1000 rotations.
4Outlet pump
The outlet pump is combined with a integral button trap, which can be
cleaned by the customer.
5Inletvalve
The outlet pump is combined with a integral button trap, which can be
cleaned by the customer
6Heater element
1800 W heater element. Machines Singel-phase 16 A or 3-phase 10 A
do also have an 1200 W heater element Machines with heater contactor
have elements with fuse.
7Level switch
There are two level switches with two levels each :
• Normal level for wash. The return level ofthe normal ofthe normal level
is used to control the length of the pumping out and decides if the
machine shall spin or not, and cut out the heat.
• Normal level for rinse
• High level for Super rinse, wool programme and cool-down
• Overfllling level, breaks the current to the inlet valves and starts the
outlet pump.

ELECTRICAL COMPONENTS
8Contactor ( onlx 3-phase machines)
The heater contactor is controlled by the level switch, and interrupts the line
connections to the heaters.
9Door lock
The door lock is electric and the power must be turned on. The timer must also be
in one of the four positions for opening, on the scale. No water in the cylinder and
the cylinder must have stoped. Pressing the pushbutton operates a solenoid
which releases the door catch. The door can be opened in an emergency. By
inserting a screwdriver about 1 cm into the hole to the left of the glassdoor and
pressing upwards. A microswitch fitted beside the door-opening solenoid
interrupts the power supply to the machine when the door is open.
10 RFI suppression
RFI suppressions are fitted in accordance with international
requirements.
11 Wiring
The internal wiring in the machine is 1,5 mm2for heater connections, 1,0 mm2
or 18 AWG for earth connections and 0,5 mm2or 0,75 mm2for others.
12 Supply cord
The supply cord must be an RKK 3x1,5 mm2or 5x1,5 mm2cable
Wiring diagram and timer diagram are provided with the machine.
Power supgly alternatives
Poweralternative are:
1 phase, 230 V 10 A
1 phase, 230 V 16 A
3 phase, 400 V 10 A
The necary changes are made directly on the terminal block. See the
instructions.
