No pumping sound, fault could be on:
Pump check by apply AC voltage directly
Power PCBA check by driving a known good pump
Connection check wire continuity
a)
b)
c)
2.
1.
No buzzer sound, fault should be on Power PCBA
Other LEDs do not light up as specied, fault should be on one of PCBAs or interconnection4.
1. Zero-crossing detection circuit error, fault should be on PCBA
1. LEDs do not light up as specied, fault should be on one of PCBAs or
interconnection
1. Iron temperature sensing circuit error, fault could be on:
Thermistor check the resistance, should be around 200+ kΩ)
Power PCBA check by test another board
Connection check wire continuity, especially hose cord
a)
b)
c)
Thermistor check the resistance, should be around 200+ kΩ)
Power PCBA check by test another board
Connection check wire continuity
a)
b)
c)
Iron heater power does not show in the power meter, fault could be due to:1.
Iron is too hot cool down and try again
Iron fuse or heating element Open Circuit check resistance between Iron Live and Neutral signal
Power PCBA check by test another board
a)
b)
c)
1. Boiler heater power does not show in the power meter, fault could be due to:
Boiler is too hot cool down and try again
Boiler fuse or heating element Open Circuit check resistance between Boiler Live and Neutral signal
Power PCBA check by test another board
a)
b)
c)
1. Boiler temperature sensing circuit error, fault could be due to:
1. E-valve does not open when steam trigger is pressed:
If iron LED still keeps blinking, trigger press is not detected, fault could be on:
-
If iron LED becomes steady on when press steam trigger, and system shows completed Self-Check mode
successfully after release the trigger check E-valve related parts and Power PCBA
-
1. Water probe error, fault could be due to:
There is water inside boiler pour out water and test again
Probe reaches end of life replace probe and test again
Connection check wire continuity
Power PCBA check by test another board
a)
Trigger mechanism or hose cord connection disconnect connector 9016 from Power PCBA
and measure continuity between the black wire (pin1) and iron Neutral, it should be short circuit
when trigger is pressed, and open circuit when trigger is released.
a)
b)
Power PCBA check by test another boardb)
c)
d)
Iron LED and hose cord wiring disconnect connector 9016 from Power PCBA and measure across
pin 3 at female side and iron Neutral to check diode characteristics
Power PCBA check by test another board
a)
b)
Iron LED does not light up as specied, fault could be on:3.
