Hot Water Problems
1. Hot Water is not Hot 85°C +/‐ 15°C (185°F +/‐ 5°F)
Also includes related instructions for Resetting the Hot Tank Overload or High
Limit Safety
Hot Water is not Hot 85 +/‐ 15°C (185° +/‐ 5° F)
NOTE: The WL250 Water Treatment System does NOT have Sleep or Power Saving Mode and
the hot water should be a of 85 +/‐ 15°C (185° +/‐ 5° F) under normal operating conditions.
The Hot temperature set point is 85°C +/‐ 15°C (185°F +/‐ 5° F) and is controlled by a thermostat
on the side of the tank.
There is a resettable overload or high limit safety above the thermostat on the side of the tank
that will trip to prevent damage to the unit if the tank is dry heated (turned on without water in
it).
The WL250 Water Treatment 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 of room temperature (ambient)
water to the 85°C (185°F) set point.
Possible Reason
No power to heater elements
Hot Tank Overload Tripped
Overload is a safety feature to
ensure the tank does not
overheat.
Thermostat or overload
"open" on Hot Tank
WL250 Manual
Check that the Red Heater and Compressor
switch is on.
Turn Red Heater and Compressor Switch on.
I = ON
Overload will "click" when pushed. The overload is
automatically reset when pressed.
See Resetting the Hot Tank Overload or High Limit Safety
Instructions that are included further below in this
Troubleshooting Section
Turn Power off. Check OHM's resistance across terminals on
each Thermostat and Overload separately.

Turn Power off; Drain hot tank; Use multi‐meter to check heater element for approximately 26 OHM’s resistance. Heating Coil Not Working Hot Tank must be empty if you are checking for continuity. Replace Hot Tank as necessary. Visually inspect wire leads gong to the hot tank; confirm proper connections to the heating elements. Loose or improperly connected wire(s) to the Hot tank life is 3‐5 years, depending on usage.

- Page 4 Reach up behind the Hot Tank and take hold of the Protective Metal Box covering the Thermostat and Overload on the Hot Tank. There are nuts that secure the metal box to the Hot Tank. However, the nuts are loose enough to allow you to remove the metal box. 5. If the nuts on the metal box are too tight, loosen the nuts securing the Hot Tank to the upper base of the unit and lower the hot tank so you can remove the metal box. For demonstrative purposes, photos below have lowered the Hot Tank from the unit. Press the reset button 6. Reattach the metal box by depressing the top flap of the 7.
