Diagnostic Guide
Before servicing, check the following:
n
Make sure there is power at the wall outlet.
n
Has a household fuse blown or circuit breaker tripped? Was a
regular fuse used? Inform the customer that a time delay fuse
is required.
n
All tests/checks should be made with a VOM (volt-ohm-
milliammeter) or DVM (digital-voltmeter) having a sensitivity
of 20,000 Ω per volt DC or greater.
n
Check all connections before replacing components. Look for
broken or loose wires, failed terminals, or wires not pressed
into connections far enough.
n
A potential cause of a control not functioning is corrosion on
connections. Observe connections and check for continuity
with an ohmmeter.
n
Connectors: Look at top of connector. Check for broken or
loose wires. Check for wires not pressed into connector far
enough to engage metal barbs.
n
Resistance checks must be made with power cord unplugged
from outlet, and with wiring harness or connectors
disconnected.

DIAGNOSTIC GUIDE
Before servicing, check the following:
Make sure there is power at the wall outlet.
Has a household fuse blown or circuit breaker tripped?
Was a regular fuse used? Inform the customer that a time-
delay fuse is required.
All tests/checks should be made with a VOM (volt-ohm-
milliammeter) or DVM (digital-voltmeter) having a sensitivity
of 20,000
1
per volt DC or greater.
Check all connections before replacing components. Look
for broken or loose wires, failed terminals, or wires not
pressed into connections far enough.
A potential cause of a control not functioning is corrosion on
connections. Observe connections and check for continuity
with an ohmmeter.
Connectors: Look at top of connector. Check for broken or loose
wires. Check for wires not pressed into connector far enough to
engage metal barbs.
Resistance checks must be made with power cord unplugged
from outlet, and with wiring harness or connectors disconnected.
SERVICE DIAGNOSTICS
NOTE: THE ONLY WAY TO ENTER SERVICE DIAGNOSTICS IS
FROM THE OFF MODE.
The SWASH™ system should be able to enter service
diagnostics mode regardless of the state of door switch and
reservoir switch.
Right after powering up, you will have 30 seconds to press
any three different keys in any sequence three times within
10 seconds to place the SWASH™ system in service diagnostic
mode. If the key sequence is not completed within the 10
second time period, entrance to service diagnostic mode will
not occur. If entrance to service diagnostic mode is successful,
the following sequence of events will occur:
1. If the reservoir switch is ON, all 15 white LEDs will flash at
a rate of 1 Hz. The tester must verify that no LED is missing.
If the reservoir switch is OFF, all 15 White LEDs will be off.
2. The service technician will instruct the tester to “Press and
hold the <15> key”. If the tester verifies that the fan relay
turned ON, this step passed. Releasing the <15> key will
turn the relay OFF.
3. Next the service technician will instruct the tester to
“Press and hold the <10> key”. If the tester verifies that the
pump relay turned ON by detecting a wattage change of
approximately 60W, this step passed. Releasing the <10>
key will turn the relay OFF. Verify that the power consumption
decreased.
4. Next the service technician will instruct the tester to “Press
and hold the <X> key”. If the tester verifies that the heater
reads approximately 1300W, this step passed. Releasing the
<X> key will turn the relay OFF.
5. The blue LED will flash at a rate of 1 Hz if the thermistor is
operating correctly.
6. The blue LED will turn ON if the thermistor is OPEN or
SHORTED.
7. Open the door and the orange LED will turn OFF.
8. Shut the door and the orange LED will flash at 3 Hz.
9. Service diagnostics will end after two minutes or if power
is cycled.
