Troubleshooting - WaterLogic WL100 Operating, Installation And Service Manual

Hot Water is not Hot 85°C ± ‐15°C (185° ± 5° F)
The Hot Temperature set point is 85°C (185°F) and is controlled by a thermostat on the side of the
Hot Tank.
There is a resettable overload or high limit safety above the thermostat on the side of the Hot Tank
that will trip to prevent damage to the unit if the tank is dry heated (turned on without water in it).
The WL100 Water Treatment System is programmable to make Cold / Ambient water – refer to
Disabling Sleep Mode instructions included further below in this Troubleshooting Section.
The WL100 Water Treatment System does NOT have Extra Hot capability and the maximum hot
temperature is 87°C (189°F).
It typically takes 10 minutes for the 500W to heat the 1.6 Liter (0.4 Gallon) of room temperature
(ambient) water to the 85°C (185°F) set point.
Possible Reason
No power to heater elements
Is unit in sleep mode?
Hot Tank Overload Tripped
Overload is a safety feature to
ensure the tank does not
overheat.
