FAULT FINDING

All fault finding procedures must be carried out 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.

1. No flow of water: 

Ensure that there is a water supply to the Cube 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 every 6 months. Check that the internal leak detection tray has 

not filled with water.

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 select the cold option.

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 

select the hot option.

6. Low flow of cold water or hot water or both: 

Check the building water pressure 

to the Cube 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 buildup needs to be defrosted.

7. Bad or plastic taste:

 If the Cube is new it may need flushing for a longer period.

8. Water leaks:

 Most leaks will be detected by either the internal Cube 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 Cube, isolate the supply and 

start normal fault finding procedures.

9. No power: 

Check the building electrical supply to the Cube is on and that the 

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

on. Test the Cube’s 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.

10. All Icons flashing and audible alarm:

 An over heat fault has been detected 

please switch the Cube off immediately and start fault finding procedures.
