Common malfunctions and causes of fully automatic washing machines
| Common Issue | Possible Causes | Inspection / Remedy |
| Machine does not start | Power not connected, door not locked, water‑inlet valve closed, control board failure, door‑lock sensor malfunction | Verify plug, check door‑lock indicator, inspect inlet valve and water‑level sensor; replace control board or door‑lock sensor if needed |
| Insufficient or no water intake | Clogged inlet hose, dirty filter screen, defective inlet valve, low water pressure | Clean inlet hose and filter, test valve’s electromagnetic coil; replace inlet valve if necessary |
| Poor or no drainage | Blocked drain pump, kinked or damaged drain hose, faulty drain valve | Clean pump filter, ensure drain hose is unobstructed; replace drain valve or pump when required |
| Inadequate spin / drum does not rotate | Over‑loaded load, machine unbalanced, loose or broken belt, motor failure, incorrect control‑board command | Redistribute laundry, level the machine, check belt tension; if motor makes no sound, test motor capacitor or replace motor |
| Excessive noise or vibration | Faulty balance sensor, worn drum or shock springs, unsecured base | Inspect shock springs, add anti‑vibration pads, tighten base feet |
| Unsatisfactory washing performance | Incorrect detergent amount, inappropriate program selection, low inlet temperature, internal residue buildup | Use suitable detergent, select program matching fabric type; periodically run dedicated cleaning cycles for drum and filter |
| Error codes displayed (e.g., E1, E3, UE) | Sensor failure, software glitch in control board, wiring short | Refer to the user manual for code meanings; reset or replace the relevant sensor/control board as needed |
| Odor development | Prolonged closed door, residual detergent or mold, incomplete drainage | Use washing‑machine‑specific deodorizer, keep door ajar for ventilation, clean pump and filter regularly |
| Automatic shutdown or program interruption | Water‑level sensor misreading, over‑heat protection, control‑board fault | Check for obstructions in water‑level sensor, ensure ventilation openings are clear; replace control board if necessary |
Preventive Maintenance Recommendations
1.Regular Cleaning : Every three months, run a dedicated cleaning cycle with a specialized cleaner to remove residue from the drum, filter, and drain pump, preventing blockages.
2.Proper Loading : Observe the rated capacity and avoid single‑side loading to reduce imbalance and spin issues.
3.Maintain Level Position : Use a spirit level to adjust the four feet, ensuring the machine is stable and minimizing vibration.
4.Appropriate Detergent Use : Choose low‑foam, high‑efficiency detergents suitable for the machine type (drum or impeller) to avoid sensor interference.
5.Power Protection : Employ a voltage stabilizer or UPS to shield the control board and motor from voltage fluctuations.
