Troubleshooting
A. Lights are off
Check that the dispenser is NOT in its “SLEEP MODE”.
If the green dot light indicator (top right of the front
plate) is illuminated, the dispenser is simply “sleeping”.
Touch any button for a few seconds to start it and all
buttons will illuminate. If ALL lights are off (including
the two LED indicators at the top right of the touch
panel), check the main power cord connection: if
plugged in, check main power switch. If the dispenser is
connected to a power source, and if the main power
switch is on, press the power reset button once or
twice. The power reset button is located at the back of
the dispenser, just below the main power switch and is
indicated with the letters “PR” (i.e. Power Reset).
B. Both the green & red LED indicators are blinking,
while all four (4) touch buttons are off and no water can
be dispensed
The DWM-20A has entered “SAFETY MODE”. There
is no water in the supply tubing or the water pressure is
too low. Or somebody has operated the unit
dispensing more than 1.5 liters without pausing, or for
more than 30 seconds without pausing. If the issue is
no water, make sure water supply valve is open or, to
address low water pressure, replace filters or use
booster pump to increase water pressure. Once the
issue is solved, turn off the unit and after three seconds
turn it on again. If the issue is solved, the unit will
restart normally.
If it persists call 1 [phone] for help.
C. There is an audible beeping sound
A leak detector is activated. In that case, proceed as
per instructions (see page 43) and reset the leak
detector to work.
D. Sparkling & Alkaline touch buttons are blinking
Indicates that the refrigeration system must be filled up.
Touch and hold both buttons contemporarily for three
seconds until ALL the buttons are blinking. Wait until all
buttons stop blinking and are solid. Now the dispenser
should be able to operate. Make sure there is water in
your pipeline flowing to the dispenser. If not, check your
water line; perhaps you need to open the shutoff valve
located at the back of the dispenser or the main shutoff
valve at your location.
E. All four (4) touch button lights are blinking
Indicates that the refrigeration system is being filled
with water. You should be able to hear it. If not, check
the water line; perhaps you need to open the shutoff
valve located at the back of the dispenser or the main
water valve at your location. If there is water in your
pipeline this operation lasts five (5) to ten (10) minutes.
