Hot Water is not Hot 86°± ‐1.5°C (187°± 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
WL350 Water Treatment System
is programmable to make Cold / Ambient water – refer to
Disabling Sleep Mode instructions included further below in this Troubleshooting Section.
The
WL350 Water Treatment System
does NOT have Extra Hot capability and the maximum hot
temperature is 87

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.
