ity. If there is no continuity, replace the cord reel patition unit.
Fuse
(Plug for UK only) Check plug fuse continuity. If there is no continuity, replace the cord reel patition unit.
Fuse of P.C.B. Ass’y
(250V, 13A) Check fuse continuity. If there is no continuity, replace P.C.B. Ass’y.
Motor continuity Check the conduction between the
terminals of the motor. If there is no continuity, replace the motor.
ON/OFF Switch Check continuity across switch
connections If there is no continuity, replace P.C.B. Ass’y.
Triac (Inside of P.C.B.) Check if there is any problem in the
triac.
(Please refer to how to check the
triac.)
If it has any problem, replace the
P.C.B. Ass’y.
P.C.B. Ass’y Check the internal parts for any-
thing unusual. (burn-out, melt-
down, etc.)
If anything unusual is found,
replace the P.C.B. Ass’y with new
one.
Motor runs but there is no suction Hose or Suction inlet Check if there is any blockage in
the hose or suction inlet. If there is any blockage, remove it.
Dust bag / Secondary filter Check if dust bag is full or Second-
ary filter is choked up. If dust bag is full, replace with a new one. If Secondary filter is
choked up, remove and clean it out
or replace.
Noise or vibration Motor fan Check dust accumulated in motor
fan (it could happen if the vacuum
cleaner has been used without cen-
tral filter).
If there is accumulated dust in the
motor fan, replace the motor and
check filter condition. (never try to
dismantle the motor fan)
Motor does not change power
(runs always at full speed) Power control Adjust the power control and check whether or not the resistance var-
ies. (Gray←→Blue)
If the resistance does not vary, then
replace the P.C.B. Ass'y.
P.C.B. Ass’y Examine the triac in the P.C.B.
Ass'y and check whether or not T1
and T2 are short-circuited.
If they are short-circuited, then
replace the P.C.B. Ass'y.
Motor runs irregularly P.C.B. Ass’y Check possible bad contact of
