and Warranties

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 WL4 Firewall is 45 PSI. Check the filters are not partially blocked, that the 

solenoid vales 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 the power to the WL4 Firewall off for 1 minute 

and then back on to reset the carbonation pump. The pump will time out if it runs 

for more than 5 minutes continuously.

8.

 Bad or plastic taste: If the WL4 Firewall is new it may need flushing for a longer 

period.

  Water leaks: Most leaks will be detected by either the internal WL4 Firewall leak 

detection system that will trigger an alarm, or it will trip the Waterlogic block located 

on the installation kit. Should you see water leaking from the WL4 Firewall, isolate 

the supply and start normal fault finding procedures.

 No power: Check the building electrical supply to the WL4 Firewall is on and that 

the power cord is plugged in. Ensure the red power switch at the rear of the WL4 

Firewall is on. Test the WL4 Firewall fuse. Check that the top cover isolation switch 

is being activated by the top cover being locked in place correctly. If all these points 

are OK then start normal fault finding procedures.

 All Icons flashing and audible alarm: An over heat fault has been detected please 

switch the WL4 Firewall off immediately and start fault finding procedures.
