Troubleshooting

Electrical Control

d. Indoor EEPROM malfunction(E7)

If the EEPROM chip

is welded on PCB,

replace the PCB

directly. Otherwise,

check whether the

EEPROM chip

plugged in PCB well?

Yes

Insert the EEPROM well

Replace the indoor PCB.

Shut off the power supply and

turn it on 5 seconds later. Is it

still displaying the error code?

e. Full-water malfunction(E8)

If the water-level switch

is inserted well?

Insert the water-level switch well

If the water-level switch

is broken?

Yes

Replace the water-level switch

If the water pump is

normal?

Replace the water pump

Yes
