TROUBLESHOOTING - Hot Water is not Hot (185
°
+/- 5
°
F)
NOTE: The WL400 does NOT have Sleep or Power Saving Mode and the hot water should be a
minimum of 185
°
F under normal operating conditions.
The Hot temperature set point is 185
°
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 WL400 does NOT have Extra Hot capability and the maximum hot temperature is 193
°
F.
It typically takes 10 minutes for the 500W to heat the 1.6 Liter of room temperature (ambient) water
to the 185
°
F set point.
Possible Reason Solution
Is unit in sleep mode?
If no water has been dispensed for 3 or more hours, unit goes into
sleep mode. Dispense hot water, wait 5 minutes, check
temperature.
If unit still does not heat proceed to “No power to heater
elements” below.
If unit does heat but you would like to disable sleep mode
instructions are included in this manual.
No power to heater elements
Check that the Green Heater / Compressor switch is
on.
I = ON
Loose or improperly
connected wire(s) to the
heating element / hot tank.
Visually inspect wire leads gong to the hot tank; confirm proper
connections to the heating elements.
Hot tank life is 3-5 years, depending on usage.
*Typically dealers swap out the hot tank at site, take back to the
shop to repair.
Overload Tripped
Overload is a safety feature to
ensure the tank does not
overheat.
Overload will “click” when pushed. The overload is automatically
reset when pressed.
*See Overload Reset Instructions Included in Manual
Thermostat or overload
“open” on Hot Tank
Turn Power off. Check OHM’s resistance across terminals on each
Thermostat and Overload separately.
Good components will indicate a closed circuit or zero OHM’s on
the meter.
Replace components as necessary.
Heating Coil not Working
Turn Power off; Drain hot tank; Use multi-meter to check heater
element for approximately 26 OHM’s resistance.
Hot tank must be empty if you are checking for continuity.
Replace Hot Tank as necessary.
