Error Code Symptom - Panasonic NP-6F2MUQNZ-NZ Service Manual

5.12.3. Error code symptom

5.12.3.1. E1 Water filling exceed pre-set time
If the inlet valve has been opened for 4 minutes but the water quantity hasn't reached the desired value (measure by pluses), E1
would occur.
When E1 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes and all the other components will be stopped
immediately. At the same time, the buzzer will alarm for 30 seconds and error 1 will be shown.
5.12.3.2. E3 Heating exceed pre-set time
If the heating element has been working for 60 minutes but the water temperature detected by NTC hasn't reached desired value.
E3 would occur.
When E3 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes. and all the other components will be
stopped immediately. At the same time, the buzzer will alarm for 30 seconds and the error 3 will be shown.
5.12.3.3. E4 Overflow
At any time, if overflow micro-switch act and keep for longer than 2 seconds, the E4 would occur. When E4 occurs, the drain pump
will run until flowmeter keep motionless for 2 minutes and all the other components will be stopped immediately.
At the same time, the buzzer will alarm for 30 seconds and error 4 will be shown.
Note: Priority level of E4 is the highest. E4 operation is valid after other error operations have done. When E4 operation has done,
all the others are invalid.
5.12.3.4. E6 Open-circuit failure of thermistor
In test program, once open-circuit failure of thermistor is detected by controller, the E6 would occur. When E6 occurs, the drain
pump will run until flowmeter keep motionless for 2 minutes. and all the other components will be stopped immediately.
At the same time, the buzzer will alarm for 30 seconds and error 6 will be shown.
5.12.3.5. E7 Short-circuit failure of thermistor
In test program, once short-circuit failure of thermistor is detected by controller, the E7 would occur. When E7 occurs, the drain
pump will run until flowmeter keep motionless for 2 minutes and all the other components will be stopped immediately. At the same
time, the buzzer will alarm for 30 seconds and error 7 will be shown.
5.12.3.6. E8 Diverter valve fault
For models equipped with diverter(alternative washing function)
In the process of test program in which diverter valve should be act, if machine doesn't detect the feeding signal of diverter valve for
15 seconds or doesn't detect the diverter valve being positioned accurately in 60 seconds, the E8 would occur.
In the process of washing program in which diverter valve should be act, if machine doesn't detect the feeding signal of diverter
valve for 15 seconds or doesn't detect the diverter valve being positioned accurately in 60 seconds, the diverter valve would stop
and the E8 would be set off after ending washing program.
When E8 occurs, the drain pump will run until flowmeter keep motionless for 2 minutes and all the other components will be stopped
immediately. At the same time, the buzzer will alarm for 30 seconds and the error code will be shown.
