• Check the pump and wire connections, then repair.
• Check the drain valve and wire connections, then repair.

Problem

Door lock or unlock error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Shut the door properly.
• If the problem continues, check the door lock and wire connection, then repair.

Problem

Water temperature sensor error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check the resistance of the temperature sensor in the heater and the wire connection, then repair.

Problem

Water inlet error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check whether the tap is turned on, whether water pressure is too low, or whether the water supply is cut off.

Problem

Heating system error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check the heater and wire connection.
• Heater resistance should be around 30 ohms (verify for your model).

Problem

Motor system error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check wire connections and the motor, then repair.

Problem

Water level in drum too high

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check and fix any blockage or kink in the water pressure switch hose.
• Check if the water inlet valve cannot stop when power is on; if so, replace the water inlet valve.

Problem

Water level sensor error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check if the wire connection to the water level sensor is loose and fix it.
• If the problem continues, replace the water level sensor.

Problem

Communication bus error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check the printed circuit board power lines and reactance lines; ensure they are fully inserted.
• If the printed circuit board is faulty, replace it.

Problem

Motor driving module communication error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check if wire connections between the control board and driven boards are loose and fix them.
• If connections are good, check and replace the control board or driven board.

Problem

Motor driving module communication error

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Check if wire connections between the control board and power boards are loose and fix them.
• If the problem continues, replace the control board and power boards.

Problem

Sub-switch continuously leaks for 10 seconds

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Open the drain pump to drain.
• Shut down the machine.

Problem

Unbalanced load during spinning

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• Ensure the washing machine is level.
• Remove the laundry to loosen it, then reload for spinning.

Problem

High voltage protection

Causes

The control system is reporting this fault. Use the checks below to narrow down wiring, sensors, supply, or mechanical issues.

Fix

• When the voltage returns to normal, the alarm clears automatically and the machine runs normally.
