No Pumping sound, fault could be on:
a. Pump →
Check by apply AC voltage directly
b. Power PCBA →
Check by driving a known good pump
c. Connection →
Check wire continuity
No Buzzer Sound, fault could be on Power PCBA
Iron LED does not light up as specified, fault could be on:
a. Iron LED and hose cord wiring →
measure across pin 3 at female side and iron Neutral to check diode characteristics.
b. Power PCBA →
Verify by using a new board
Other LEDs does not light up as specified, fault could be on one of PCBAs or
interconnection
Check the resistance, should be around 200+kΩ
Power PCBA →
Verify by using a new board
Check wire continuity
Iron heater power does not show in the power meter, fault could be due to:
a. Iron is too hot →
Cool down and try again
b. Iron fuse or heating element Open Circuit →
Neutral Signal
Check the Resistance, should be around 200+KΩ
Power PCBA →
Verify by using a new board
Check Wire Continuity
Cool down and retry
Neutral Signal
Verify by using a new board
Disconnect connector 9016 from power PCBA and
Check Resistance between Iron Live and
Check resistance between Boiler Live and
