16. Drain Valve Malfunction (Coin)
NO
2A
1A
YES
With the machine running, the basket moving and the water
valves on, the machine does not hold water (i.e., the
machine does not fill).
Note: Before proceeding to the next step, take voltage
readings across input connector J9-3-1* and J9-3-3 and also
across J9-3-3 and the DN wire. This is a test to check if the
ACN (neutral) circuit is intact all of the way to the drain
valve. This will also check the function of the voltmeter.
If 120 Volts** are present on both readings, continue to the
next troubleshooting step. If 120 Volts** are not present,
contact Alliance Laundry Systems’ Customer Service
Department for assistance in locating the broken circuit.
Is there voltage
(120 Volts** AC)
across the drain
valve wires
(DV and DN)?
Remove the drain hose and inspect the drain valve,
checking for blockage, a damaged seal and that the
drain valve closes when 120 Volts** AC are present.
Remove all blockages.
Replace the drain valve if the seal is damaged or
if the drain valve does not close when 120 Volts**
AC are present.
*Note: All voltage readings should be taken from J9-3-1 as a neutral point.
**Note: All voltage readings are approximate.
Is there voltage (120 Volts** AC)
across J-3 pin 1 and input
connector J9-3-1*?
Check the connection between J3-1 and the
drain valve.
Replace or repair the wires and/or wire ends
as needed.
6A
4A
3A
YES
Is there voltage
(120 Volts** AC)
across 12a
on the timer and
input connector J9-3-1*?
NO
5A
Check the connection between 12a on the
timer and J3-1-1.
Replace or repair the wires and/or wire ends
as needed.
Assuming that the basket turns, that the water valves
turn on and that the machine does not hold water
(i.e., fill up), replace the timer or contact Alliance
Laundry Systems’ Customer Service Department to
verify that all checks have been done correctly.
