b. Remove the connecting screws around the bottom pan and the screws to
thecirculation motor support, the drain motor and the pressure switch bracing bar.
ٛ
c. Check the capacitor and, if necessary, replace a new one.
ٛ
d. Check the circulation pump for defects. In case of defective pump, replace it
inthe following manner:
ٛ
(1) Remove the inlet hose clamp and the circulation pump;
ٛ
(2) Replace a new circulation pump;
ٛ
(3)Put on a new inlet hose clamp and connect the tubes and wires;
ٛ
(4) Tighten the clamp.
e. Check the drain pump for defects. In case of defective pump, replace it in the
following manner:(1)Remove the inlet hose clamp and the drain pump;
ٛ
(2) Replace a new drain pump;
ٛ
(3) Put on a new inlet hose clamp and connect the tubes and wires;
ٛ
(4) Tighten the clamp.
ٛ
f. Check the connecting tubes and replaced the damaged ones.
Removal of Drainage Troubles
ٛ
a. Check the drain hose for twist, air bubble or blockage and make necessary
correction.
ٛ
b. Check whether the motor is burnt. If so, replace the drain pump as specified
above.
XIV. Overheat Thermostat
This thermostat is designed to prevent overheating of the heating element.
Thetemperature limitation is set at 90 . Below this limitation, the circuit is closed.
Oncethe temperature rises above this limitation, the circuit is cut, protecting the
heatingelement from being burnt.Removal and replacement:Remove the outer
casing.Remove the thermostat connecting wire and check with an ohmmeter whether
thethermostat circuit is closed in normal temperature and opened when temperaturerises
above 90 . If the result if positive, the thermostat is normal. Otherwise, it failsand shall be
replaced.From the lower left side, you can see the thermostat at the end of the
sump.Remove the nuts on the thermostat mounting plate.Remove the mounting plate
and the thermostat.Replace a new thermostat and add some heat conducting silicone
grease to its end.Wrench tight the nuts on the thermostat mounting plate and connect
the thermostatconnecting wires.Replace the outer casing.
XV. Water Temperature Thermostat
This thermostat is designed to inspect the water temperature and control theheating
element. The temperature control point is set at 45 (different temperaturesare available
and can be observed from the thermostat). The circuit is openedbelow this temperature
and closed above it.Removal and replacement:Remove the outer casing and bottom
pan.Remove the connecting wires behind the sump and check with an ohmmeterwhether
the thermostat circuit is opened in normal temperature and closed whentemperature
rises above 67 . If the result if positive, the thermostat is normal.Otherwise, it fails and
shall be replaced.Remove the screws and the mounting plate.
Replace a new thermostat and the mounting plate. The mounting plate shall press tight
