Timely and accurate fault troubleshooting reduces laundromat downtime and revenue loss. Coin-operated laundry equipment has high-frequency common faults in payment, water system, power system, and drying system. Standardized troubleshooting processes enable operators to quickly solve problems and restore normal operation.
Payment System Common Faults
Coin jamming and identification failure are caused by foreign objects, deformed coins, and dust accumulation. Regular cleaning and sorting can effectively prevent and solve such problems.
QR code recognition failure is related to screen dirt, network fluctuation, and module aging. Clean the screen and check network signal to restore normal use.
Card reading failure is mostly due to card reader dust and sensor wear. Regular maintenance and component replacement ensure sensitivity.
Water System Faults and Solutions
No water intake or slow water intake is caused by blocked filters, aging water valves, and insufficient water pressure. Clean filters and inspect waterway components.
Poor drainage and water retention result from blocked drain pipes and damaged drain pumps. Clear blockages and replace faulty accessories.
Water leakage faults occur in aging sealing rings and loose pipeline joints. Replace seals and fasten interfaces.
Washing and Dehydration Abnormal Faults
Abnormal vibration and loud noise are caused by unbalanced load, loose shock absorbers, and bearing wear. Adjust load balance and maintain shock absorption system.
Failure to spin dry is related to unbalanced protection start and drainage blockage. Troubleshoot drainage and redistribute loads.
Weak cleaning effect is caused by unreasonable load, aging motor, and insufficient water level. Adjust operating parameters and inspect power system.
Dryer System Common Faults
No heating or slow drying is caused by blocked lint ducts and damaged heating elements. Clean air ducts and replace heating parts.
Excessive dryer noise and fan failure are due to fan aging and foreign object jamming. Clean and replace fan components.
High internal humidity and long drying time result from poor ventilation. Optimize on-site ventilation conditions.
Circuit and Control Faults
Unable to start and sudden shutdown are caused by circuit overload, poor contact, and overheating protection. Check power supply and heat dissipation conditions.
Program disorder and parameter confusion are related to system crash and signal interference. Restore factory settings and stabilize power supply.
Fault Prevention Daily Mechanism
Standardize user operation guidelines to reduce faults caused by misoperation.
Implement regular component inspection to realize early warning and advance maintenance.
