Error Code Test program

E4
Overflow
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 (
if the model with the pressure switch (83/63),drain pump would run till the pressure switch reset
and continue draining for 60 seconds.
) 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.
E6
Open-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 (
if the model with the pressure switch (83/63),drain pump would run till the pressure switch reset and
continue draining for 60 seconds.
) 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.
E7
Short-circuit failure of thermistor
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 (
if the model with the pressure switch (83/63),drain pump would run till the pressure switch reset
and continue draining for 60 seconds.
) 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.
