Hot Water is not Hot 85°C ± ‐15°C (185° ± 5° F)
The Hot Temperature set point is 85°C (185
°

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

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
