Troubleshooting Procedures
!
WARNING
To avoid risk of electrical shock, personal injury or death; disconnect power to washer before servicing, unless
testing requires power.
5. Advance to the
Board Output Test
and press
extra rinse
to
unlock the door
. An unlock
signal will be sent to the solenoid every
second for 10 seconds.
If the door does not lock, use a voltmeter, look
for 120VAC, 60 millisecond pulse to the locking
solenoid.
If signal is present
, then the door lock
solenoid is bad and the door lock mechanism
must be replaced. To stop the signal, press
extra rinse
again.
If signal is not present,
check electrical
connections at switch or at control board.
Check for proper outputs from the control
board at Conn P8(3) and Neutral leg of power
cord. If voltage is present, fix electrical
connections or change wire harness. If no
voltage is found, go to P8(4) and Neutral on
power cord to verify 120VAC coming into the
board. If voltage is not present check the door
actuator switch. (make sure door is closed.) If
voltage is present, change machine control
board.
No Fill Test
1.
Close the door and start a spin cycle to drain all
water from the washer to reset the pressure
switch.
2.
Press
off
and open door to verify all water is
removed from the washer. If water still present,
go to
Will Not Drain
diagnostics.
3.
If water is drained out, close the door and go to
Service Mode
, press
delicates
and
heavy
soils
keys for 3 seconds. If it is likely to need
access to the water valve for voltage checks,
consider raising the top cover now and close
the door so that the following steps will not need
to be repeated.
4.
While in
Service Mode
, press the
hand wash
key places the washer into the
Board Input
Test
.
5.
Check the lower water level by pressing the
hand wash
key.
6.
"
_1
" indicates the washer is full. If full, check
the lower water level input at the machine
control board by reading DC voltage between
P4(4) and P4(8). If voltage is present at the
machine control board, check voltage at
pressure switch between BU and BR . If
voltage present at pressure switch, replace
pressure switch.
If voltage is not present at pressure switch,
check or replace harness. If no voltage is
present at the Machine control board, replace
the machine control board.
7.
"
_0
" indicates the washer is empty: If empty,
press the
wrinkle free
key to check the high
water level.
8. "
--
1
" indicates full. If full, check the high water
level input at the machine control board by
reading 120 VAC voltage between P1(4) and
Neutral P6(2). If120
VAC is not present at the machine control
board, check continuity at pressure switch
across GY and YL. If no continuity, replace
pressure switch. If continuity, check door
switch and harness to pressure switch and
harness from pressure switch to Machine
control board. If 120 VAC is present at the
Machine control board, replace the machine
control board.
9.
"
--
0
" indicates empty. If empty, exit
Board Input
Test
mode by pressing the start/pause key.
Then enter
Board Output Test
mode by
pressing the
rinse
key.
10. Turn the cold water valve on by pressing the
wrinkle free
key. Check for cold water flow at
the dispenser. If no cold water flow, check the
cold water valve for 120 VAC between BU and
WH. If 120 VAC is present at the cold valve,
replace the water valve. If 120 VAC is not
present at the cold valve, check for 120 VAC at
the machine control board between P1(3) and
Neutral. If 120 VAC is present at the machine
control board, check or replace the harness. If
120 VAC is not present at the machine control
board, replace the machine control board. If
cold water flows, turn the cold valve off by
pressing the wrinkle free button.
11.Turn the hot on by pressing the
cotton sturdy
key. Check for hot water flow at the dispenser.
If no hot water flow, check the hot water valve
for 120 VAC between OR and WH. If 120 VAC
is present at the hot valve, replace the water
valve. If 120 VAC is not present at the hot valve,
check for 120 VAC at the machine control board
between P1(2) and Neutral. If 120 VAC is
present at the machine control board, check or
replace the harness. If 120 VAC is not present
at the machine control board, replace the
machine control board.
