TROUBLESHOOTING THE WL850HV
1. No Cold Water Flowing: There are a number of reasons that could be causing this
problem. 1) Check if the water in the building is turned off! 2) Check if the isolating
valve has been turned off! 3) Check if the filter blocked with sediments or passed
its change date! 4) Check if the solenoid valves are operating! 5) Check if the cold
tank has frozen. 6) Check if the red LED warning light is flashing!
2. Water Flows but is Not Cold: 1) Check that the compressor switch at the rear
of the machine is turned on. 2) Have you just taken more than 3 jugs of water?
The machine takes about 30 min to recover temperature after heave use. 3) Is the
machine sited in an area with an ambient room temperature in excess of 30°C. 4)
Does the machine have a 5cm air gap around it? 5) Test the machine cooling system
for loose of refrigeration gas. If the compressor is continually running hot and mot
making cold water, then this could mean it need gas. Check the compressor to
ensure it is running. Make sure the thermostat is adjusted correctly.
3. Water has a Plastic or Funny Taste: 1) If the machine is new it may need to be
flushed. 2) Has the machine been unused over a long weekend? Then flush 5 litres of
water before using. 3) Fit a new filter if it has passed its changing date. 4) Contact you
local dealer if adverse local water conditions are causing taste problems.
4. Restricted or Slow flow of cold or sparkling water: 1) Check that the water
supply is above 1.5 bar or 21 PSI, as the machine will not function correctly below
this! 2) Check that the gas bottle is not empty. 3) Check that the filter is not blocked
or past its changing date. 4) Check that the faucet is not blocked.
5. Vend buttons sticking:
1) this fault is caused by dirt or cleaning material filling
the gap around the button. Do not use cream or abrasive surface cleaner.
6. Red LED Warning Light flashing: 1) the pump has been running too long and
has timed out. Please check the water supply to the pump. Te reset the pump turn
the power on and off to the machine.
7. Machine no Power: 1) check that the machine switches are on the back of the
machine. 2) Isolate the power supply and check the machine fuse. 3) Check that the
power cord is plugged into the back of the machine and is pushed home. 4) Check
that the power cord is plugged into the wall socket and is switched on. 5) Check that
there is no problem with the building electrical supply.
8. No Hot Water: 1) Make sure the heater switch is on at the rear of the machine. 2)
Does the hot tank need to be de-scaled? 3) Check the power supply to the heating
element. 4) Disconnect the power and check the resistance of the heating element.
5) Is the water supply to the machine turned on? 6) Are the solenoid valves operating
correctly? 7) Is the filter blocked or past its change by date?
9. Factory sets the cold water at 5°C. Waterlogic strongly advice that you do not
adjust the water to a colder temperature. Care should be taken if the thermostat is
adjusted colder as this could increase the risk of the cold tank freezing. It is advised
that any adjustment to the thermostat to male the water colder be done in small
turns of the thermostat of a few degrees at a time. Allow the compressor to cycle on
and off, check that the temperature is as required before any further adjustment. In
the event that the cold tank should freeze then please turn the compressor switch
mounted at the rear of the machine to the off position. Allow the machine to stand
for one hour. Flush 1 litre of water through the machine, adjust the thermostat back
to the factory position set point as marked and turn the compressor switch back on.
