RESISTANCES OF DRAIN MOTOR WINDING AND ALL CONNECTIONS
IN THE DRAIN CIRCUIT. FIX / REPLACE OPEN CONNECTION / PART.
DEBRIS STUCK IN DRAIN MOTOR IMPELLER. 1. UNPLUG DISHWASHER OR DISCONNECT POWER.
2. REMOVE DRAIN MOTOR AND DISLODGE DEBRIS FROM IMPELLER.
OPEN FUSE ON CONTROL TO DRAIN MOTOR. REFER TO FUSE SERVICE AND RESISTANCE CHECK ON PAGE 6-4 IN
“TESTING” SECTION.
DRAIN MOTOR DRIVE CIRCUIT ON THE
CONTROL.
UNPLUG DISHWASHER OR DISCONNECT POWER AND REPLACE
CONTROL.
3-DRAIN
STUCK ON
DRAIN MOTOR DRIVE CIRCUIT ON THE
CONTROL.
1. UNPLUG DISHWASHER OR DISCONNECT POWER.
2. INSPECT DRAIN MOTOR AND CONNECTIONS FOR OVERHEATING/
SHORTING. IF EVIDENCE OF OVERHEATING/SHORTING EXISTS,
REPLACE.
9-DIVERTER 1-CAN’T
FIND
POSITION
CORRODED OR LOOSE CONNECTION IN
DIVERTER SENSOR / MOTOR CIRCUIT, OR OPEN/
SHORTED SENSOR/MOTOR.
1. CHECK OPERATION IN SERVICE DIAGNOSTICS CYCLE. LISTEN FOR
CAM CLICKING AS IT ROTATES OR INSPECT SHAFT WITH MIRROR
TO SEE IF ROTATING DURING DIVERTER INTERVAL. IF ROTATING,
THEN LIKELY THE SENSOR CIRCUIT.
2. UNPLUG DISHWASHER OR DISCONNECT POWER AND CHECK
CONNECTIONS IN DIVERTER SENSOR AND MOTOR CIRCUIT WITH
METER. FIX / REPLACE CONNECTIONS / PARTS.
3. INSPECT DIVERTER SENSOR FOR EVIDENCE OF WATER OR
CONTAMINANTS; IF YES, REPLACE.
MECHANICAL BINDING OF DIVERTER SHAFT /
DISC.
CHECK OPERATION OF DIVERTER MOTOR DURING DIAGNOSTICS.
INSPECT DIVERTER SHAFT WITH MIRROR IF MOTOR APPEARS TO
BE ON (HUMS, VIBRATES) BUT YOU SEE LIMITED ROTATION, THEN
REPLACE DIVERTER AND SEAL.
OPEN FUSE ON CONTROL TO DIVERTER MOTOR. REFER TO FUSE SERVICE AND RESISTANCE CHECK ON PAGE 6-4 IN
“TESTING” SECTION.
DIVERTER MOTOR DRIVE CIRCUIT ON THE
CONTROL.
UNPLUG DISHWASHER OR DISCONNECT POWER AND REPLACE
CONTROL.
2-STUCK ON DIVERTER DRIVE CIRCUIT ON THE CONTROL. 1. UNPLUG DISHWASHER OR DISCONNECT POWER AND REPLACE

OPERATION/FAULT DETECTION (NOTE 10). IF FAILURE STILL
EXISTS THEN:
- UNPLUG DISHWASHER OR DISCONNECT POWER. CHECK WIRING
CONNECTION OR DAMAGE AT CONTROLLED LOWER SPRAY ARM
SENSOR.
- REFER TO FUSE SERVICE AND RESISTANCE CHECK ON PAGE 6-4 IN
“TESTING” SECTION. 1 (REPLACE CONTROL IF OPEN).
- CHECK FOR OPEN OR SHORTED LOWER SPRAY ARM MOTOR
WINDING RESISTANCE. REPLACE DIVERTER MODULE.
