5.
Display indicates “No Water Supply”
Possible Reason
Solution
The Flow Counter is
Enabled
A No Water Supply Fault will occur when the Flow Counter is enabled
because there is no longer a flow counter device in the unit and will be
looking for a signal it cannot find. To check this, enter into programming
mode and scroll down to Filters Life and Enter.
Filters Life should be displayed in Days or Months and not in Liters or
Gallons. Always ensure the Filters Timer is on and set to the Default of
None then save and exit (select button 4 = Extra Hot) to store this setting.
Enabling the Filters Timer disables the Flow Counter. Always check the
programming first to see if the Filters Life is shown in Days or Months
instead of Gallons or Liters to validate the selection. Filters Timer should
always be enabled and set and saved to NONE. Filters Life should always
be displayed in time (Days or Months) instead of flow (Gallons or Liters).
The Sparkling Injection
Pump Runs Too Long
A “No Water Supply Fault” will occur if the Sparkling Water Injection
Pump runs for 10 minutes. This is a safety feature to prevent the Pump
from being damaged. When operating properly, it should take about 1‐
1/2 minutes for the Pump to inject enough water to completely fill the 1
liter Sparkling Chamber. This can occur when there is not adequate
supply of water to fill the Sparkling Chamber, or the pump cannot
overcome the CO
2
pressure in the Sparkling Chamber, or there is not a
proper ground signal from the level sensor in the Sparkling Chamber to
shut off the pump once it is filled.
The water supply is not adequate. Ensure proper water supply to the
cold circuit. Remember that the
WL500 Water Treatment System
contains two Carbon Filters inside the Front Access Panel. The first
Filters head has a valve that will shut off water supply when the
Filters is removed. The water supply has been shut off or is not
adequate. Always ensure there is 40‐60 psi and 1.5 Liters/Min (0.4
gal/min) water supply.
I.
The internal Filters is removed and the Safety Valve in the first
Filters head is stopping water supply.
II.
The Filters have become fouled and plugged, thereby starving
the pump of make‐up water. Change the Filters.
III.
There is not adequate water supply to the unit
IV.
The drip tray is full and/or a Solenoid Valve is not opening to
allow water to pass.
The CO
2
gas pressure is above 45 psi, and the Booster Pump has
dead‐headed and cannot fill the Sparkling Chamber.
