Fault Code E7 - Detergent Diverter Valve
1. Check the harness connections on the detergent
diverter valve and at the controller (P204 refer p56)
for signs of any water damage, corrosion or arcing.
Replace if damaged.
2. Ensure the harness is securely connected at the
controller and component.
3. Check the detergent diverter valve in diagnostic
“HO” mode ( refer p30 & 31) , if after 10 seconds a
long low tone is played and repeats every second,
then the detergent diverter solenoid is faulty and
needs to be replaced.
4. Check the resistance of the coil on harness P204, on
pin pair 3 & 4, the reading should 65 +/- 10 Ohm.
5. Once solenoid is replaced, repeat step 3 to ensure
new solenoid is OK.
6. If fault still occurs, replace the controller.
Fault Code E7 - Sub Code 02 - Under Current
1. Check the harness connection at both the controller and solenoid.
2. Check the detergent diverter valve in diagnostic “HO” mode ( refer p30 & 31). If after 10 seconds a
long low tone is played and repeats every second, then the detergent diverter solenoid is faulty
and needs to be replaced.
3. Check the resistance of the coil on harness P204, on pin pair 3 & 4, the reading should 65 +/- 10
Ohm. Replace if open circuit.
4. If the fault still occurs, replace the controller.
Fault Code E7 - Sub Code 03 - Over Current
1. Check the harness connections at both the controller and solenoid.
2. Check the detergent diverter valve in diagnostic “HO” mode ( refer p30 & 31). If after 10 seconds a
long low tone is played and repeats every second, then the detergent diverter solenoid is faulty and
needs to be replaced.
3. Check the resistance of the coil on harness P204, on pin pair 3 & 4, the reading should 65 +/- 10
Ohm. Replace if short circuit.
4. If the fault still occurs, replace the controller.
