Fault Finding; Advisory Icons - WaterLogic WL3 Firewall Technical Manual

FAULT FINDING

All fault finding procedures must be carried by a technician trained by Waterlogic
International or their nominated distributor. Please take great care and suitable
health and safety measures when fault finding on live electrical parts.

ADVISORy ICONS

fault. Check the water supply is turned on; if the fault persists please call your
authorised service agent.
FILTRATION LED
Filtration is Active.
PURIFICATION LED
This led shows the UV lamp is operating correctly. Should this icon be continuously

1. No flow of water: Ensure that there is a water supply to the WL3 Firewall from
the building and that the installation isolation valve is turned on. If the installation kit
has an anti-leak device included in it (as Waterlogic Installation kit) then make sure
it has not tripped.
2. No flow of water: Check that the water filters are not blocked and that they are
in date and are screwed home securely into the filter head. Waterlogic recommend
filters are changed at 6 months.
3. The hot water is not hot and cold water is not cold: Make sure the green heater
compressor switch is turned on.
4. There is hot water flow but cold water is not flowing: This may be due to the
cold water tank being frozen. If so disconnect power supply for one hour to allow
the tank to defrost, and then flush the cold water system. Check the temperature
settings are correct. If the cold tank is not frozen then check the solenoid valve is
operating correctly and being turned on and off when you push the cold button.
5. There is cold water flow but hot water is not flowing: This may be due to
calcium build up in the hot tank or the hot water outlet. De-scale the hot tank. Check
the hot water solenoid valve functions correctly and turns on and off when you hold
the hot and extra hot buttons together for 3 seconds.
6. Low flow of cold water or hot water or both: Check the building water pressure
to the WL3 Firewall is 45 PSI. Check the filters are not partially blocked, that the
solenoid valves function correctly, hot tank calcium build up need to be de-scaled,
cold tank ice build up needs to be defrosted.
7. No sparkling water: Ensure the CO2 bottle is full and turned on and set at 45
PSI. Turning the gas pressure above 45 PSI can stop the production of sparkling
water. Check the pump Icon. If flashing turn off the power to the WL3 Firewall for 1
minute and then back on to reset the carbonation pump. The pump will time out if it
runs for more than 8 minutes continuously.
8. Bad or plastic taste: If the WL3 Firewall is new it may need flushing for a longer
period.
9. Water leaks: Most leaks will trip the Waterlogic block located on the installation
kit. Should you see water leaking from the WL3, isolate the supply and start normal
fault finding procedures.
10. No power: Check the building electrical supply to the WL3 Firewall is on and
that the power cord is plugged in. Ensure the red power switch at the rear of the
WL3 Firewall is on. Test the WL3 Firewall fuse. If all these points are OK then start
normal fault finding procedures.
11. All Icons flashing and audible alarm: An over heat fault has been detected
please switch the WL3 Firewall off immediately and start fault finding procedures.
