TROUBLESHOOTING
Hot Water is not Hot (185
°
+/- 5
°
F)
NOTE:
The
WL270
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
°
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
WL270
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
No power to heater elements
Check that the Red Heater and Compressor
switch is on.
Turn Red Heater and Compressor Switch 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.
