Daily Inspections
● If the machine has not been used for more than 2 hours, it is recommended to run Program 991 first to flush the internal pipelines of the machine.
● Timely clean impurities, lint, scale, and laundry agents remaining in the washing machine water.
● Regularly check and clean the filter of the inlet valve.
● Periodically inspect and remove lint remaining on the drain valve to prevent blockage.
● Periodically inspect and remove lint remaining on the heating tube to avoid prolonged heating time or damage to the heating tube.

Semi-Annual Maintenance
● Re-examine the installation details and inspect external water and electrical circuits.
● Run Program 991 and check for water leakage during water inlet and drainage.
● Verify the accuracy of the weighing system.
● Perform an idle run of Program 6N or 4N to ensure all indicators are normal.

Annual Maintenance
● Inspect and calibrate various parameters: water level calibration, rotation speed calibration, temperature calibration, weight calibration, etc.

Descaling
● If the machine operates in an area with hard water, follow these descaling steps:

1.Place 0.5kg of citric acid into the detergent drawer.
2.Start Program 7N or 9N.
3.Run Program 7N or 9N again for flushing.

Cleaning Residual Detergent
● Detergent may accumulate on the outer surface of the inner drum, the outer drum, or in the detergent pipelines. Run Program 7N or 9N in idle mode (without adding detergent). If foam appears during operation, it indicates residue. Repeat Program 7N or 9N until no obvious foam is visible.
