Common problems, possible causes and solutions. The machine shakes too much during washing. The machine is not stable. Check the ground and feet to ensure that the machine is properly placed. The washing machine is not level. Adjust the level of the machine according to the installation guide. The sample is too tight. Noise The dehydration process will have a lot of noise, but it is a normal phenomenon. The load sensing system will work for a few minutes before the washing starts. Water leakage. Connection problem. Is the connection of the water inlet and the water outlet normal? Is it normal that the washing machine can’t work or can’t inject water to supply water? Check whether the water valve connection is normal, cold, and hot water connections should be turned on. Power supply connection, ground wire connection, do not use the extension cord. Please do not add other samples after the start of the washing procedure to avoid unbalanced operation of the inner tank. Dehydration failure. Increase the dehydration rate appropriately. The sample is too tight or unbalanced. Adjust the sample to avoid too much sample, too tightly wrapped detergent Reduce the amount of detergent more appropriately to remove excess foam.

ISO 20345 and ASTM F2413 are the two most recognized safety footwear standards used worldwide to evaluate protective footwear performance. Although both standards define minimum requirements for impact resistance and compression protection, differences in test energy levels, compression loads, marking systems, and hazard classifications can affect certification results. This article explains the key differences between ISO 20345 and ASTM F2413, helping footwear manufacturers, exporters, and quality control teams select the correct testing standard and improve compliance with international safety requirements.
Slip resistance is one of the most critical performance indicators for modern footwear, especially safety shoes used in industrial and high-risk working environments. Slip and fall accidents frequently occur on wet or smooth surfaces, posing serious risks to workers and consumers. To prevent such accidents and improve product safety, footwear manufacturers widely use professional testing equipment such as Shoe Slip Resistance Tester and Footwear Slip Testing Machine. These devices simulate real walking conditions to measure the coefficient of friction between the shoe sole and various surfaces. This article explores the working principle, features, applications, and industry significance of shoe slip safety tester, explaining why accurate slip resistance testing is essential for footwear safety, product development, quality control, and compliance with international standards.
