Inform customer
shock
which the machine is connected to correct for
using multimeter.
proper earthing
Check voltage between
Phase & Neutral
Phase & Earth
both should be equal.
Check continuity between
Neutral & Earth
If found to be short Earthing is
defective
2
Fuse
Blown
Using multimeter check continuity
between both the ends.
Replace the fuse
3
Power cord
Discontinuity
Check
for
proper
continuity
between plug side and machine
side also check for short circuit
between wires
Replace
power
cord
4
capacitor
Not functioning
WARNING
DISCHARGE
BEFORE
HANDLING
Check the capacitor with the
multimeter in continuity mode.
The meter should first read ohms
and gradually the needle should
swing back to infinity Ohms. It
indicates a good capacitor and
any thing other than this is
defective.
Replace
the
capacitor
5
Wash Motor
Does not run
Check the winding resistance
using a multimeter between wires
BLACK & BLUE 37.6 Ohms
approx. BLACK & YELLOW 42.6
Ohms. If the resistances are not
as per the given value it could be
short or open
Replace the wash
motor
6 Spin Motor
Does not run
Check the winding resistance
using a multimeter between wires
BLACK & BROWN 69 Ohms
approx. BLACK & WHITE 77.5
Ohms. If the resistances are not
as per the given value it could be
short or open
Replace the Spin
motor
