The Northern Hemisphere has entered a hot and rainy season. Temperatures are rising while air humidity is increasing significantly. Laundry plants enter an annual peak operating season. Large amounts of sweat stains and grease adhere to summer garments and linens. Laundry volume doubles during this period. Washers continuously operate throughout the day. Under a high-temperature and high-humidity environment, equipment failures are more likely to occur, such as mildew inside the drum, detergent scale buildup and pipe blockage, door seal aging, water leakage, and electrical component failure caused by moisture. Equipment failures may interrupt order fulfillment and reduce linen cleaning performance. They may also significantly increase maintenance costs and reduce equipment service life.
As a global professional manufacturer of commercial and industrial washers, Kingstar has specialized in the laundry equipment industry for many years. Based on summer operating challenges faced by laundry plants, Kingstar has developed a comprehensive summer washer maintenance guide. It is committed to helping with moisture prevention, scale buildup removal, and routine inspection. Therefore, customers can achieve stable production during peak season.
Core Failure Causes
- High-load operation
In summer, the indoor temperature often exceeds 35℃. Motors and variable frequency drives (VFDs) of washers continuously operate for a long time. Under poor heat dissipation conditions, component temperature remains high. This easily triggers overheating protection. In severe cases, it may result in motor winding aging and burnout.
- Mildew and corrosion risks
In rainy areas, the air humidity remains at excessive levels. Residual water easily accumulates in the washer drum, door sealing ring, detergent drawer, and drain pipeline. Detergent scale with moisture creates an environment that develops black mold and bad odors. Corrosion and water leakage appear on common steel machines, which affects laundry safety.
- Heavy-soil stain buildup
Summer linens have more sweat stains, body oils, and dust. These stains adhere to the drum, drain pump, and inner walls of pipelines for a long time. This causes poor drainage and increased pump load. It also accelerates the wear of bearings and seals.
Summer Maintenance Guide
SUS304 stainless steel is used for all inner drums, outer tubs, and water-contact components of Kingstar commercial and industrial washers. It prevents corrosion issues at the source. The rolled-edge gap of the loading door opening is 4-6 mm. Combined with a convex glass door, this reduces linen getting stuck and foreign objects entering pipelines. Kingstar equipment adapts to high-frequency heavy-soil washing applications in summer. Daily maintenance operations are as follows.
- Daily ventilation
After laundry operations, do not close the machine door and push in the detergent drawer. Keep the door open while removing the detergent drawer to evaporate residual moisture. Kingstar’s widened convex glass door offers a larger ventilation area. This helps quickly remove moisture to prevent mildew growth, black spots, and bad odors inside the gasket area and inner drums.
- Regular high-temperature self-cleaning
It is suggested to do a deep cleaning for the entire machine every 1-2 months. Remove the linen from the drum. Add a specialized descaling cleaner. High-temperature flush pipelines, drums, and drain pumps, which breaks down hardened detergent scale and grease stains. Kingstar equipment has a removable automatic detergent drawer. Disassemble it weekly and soak it in water for cleaning to prevent detergent clumping and outlet blockage.
- Daily sealing gasket cleaning & weekly drainage system cleaning
Silicone gasket folds easily develop water and dirt accumulation. After daily operation, wipe away residual water in the gap, hair, and other foreign objects with a dry cloth. Check the sealing gasket for cracking and aging. Disassemble and clean drain filters and pumps weekly. Kingstar large-diameter drain outlet makes it more convenient to clean hair and loose threads. This effectively prevents pipeline blockage as well as error alarms and shutdowns.
- Routine water inlet hose inspection
High temperature accelerates silicone hose cracking and aging. Kingstar washers use pressure- and heat-resistant braided hose. They have a longer service life than common hose materials. Check the hose monthly for any bulging, water seepage, and loose connections. Hoses used for 5 years should be replaced to prevent water accumulation and order disruption caused by hose damage during peak season.
Moisture Prevention Points
Keep the windows open for ventilation in laundry rooms. In humid areas, fans and dehumidification equipment can be installed to reduce indoor temperature and humidity.
If the equipment is shut down for a long time, disconnect the main power supply. Remove residual water in the drum. Keep the machine door open during the process. Place desiccants in the laundry room, which prevents circuits and metal components.
Check power cords and control panel connectors weekly for any moisture damage and overheating. Kingstar equipment has a self-diagnosis system. Automatic pop-up alerts appear in case of abnormal situations. With manual inspection, they provide dual protection for electrical safety.
Common Misconceptions
- Misconception 1
A properly operating machine does not mean it requires no maintenance. Scum buildup and mildew inside drums and pipelines are invisible to the naked eye. Drainage failures and odors may suddenly occur over time.
- Misconception 2
There are many orders during peak season. Equipment continuously operates without interruption. It is suggested to shut down for 30 minutes for cooling after high-load operation for 4-6 hours. This helps reduce heat-related motor wear.
- Misconception 3
Only clean the inner drums, but overlook hidden areas like drain pumps, pipeline, and detergent drawer. In a humid environment, foreign object accumulation easily clogs water channels of the entire machine.
Q&A
Q1: In humid summers, will Kingstar washers with 304 stainless steel bodies rust?
A1: Water-contact components of the entire machine use SUS304 stainless steel, which is corrosion-resistant. But it is necessary to ensure daily ventilation and dryness. This can prevent long-term water accumulation from soaking sealing gaskets. It can also prevent component aging and water leakage.
Q2: How often is it proper to do a high-temperature cleaning for washers in summer?
A2: Laundry plants and hotel linen processing centers should perform cleaning once a month. Kingstar equipment’s high-temperature self-cleaning programs can quickly remove detergent scale buildup and mildew.
Q3: With peak order volumes, how can laundry plants shut down a Kingstar washer for heat dissipation?
A3: Shut down a washer 30 minutes after 4-6 hours of operation. At the same time, clean door seals and drain filters. This can cool motors as well as protect the machine, which does not affect the whole operation.
