Running the spin cycle more than once in a high-efficiency front-loading washing machine typically does not damage the motor. These machines are designed to handle multiple spin cycles without causing harm to the motor or other components. However, it is worth noting that running excessive spin cycles may put additional stress on the machine and could potentially contribute to increased wear and tear over time.
If you find it necessary to run multiple spin cycles, it may be an indication that the load you are washing is particularly heavy or unbalanced. In such cases, redistributing the load or removing some items may help achieve better results. It's also worth checking the machine's manual or consulting the manufacturer's guidelines for any specific recommendations or limitations regarding the number of consecutive spin cycles.
Remember, it's generally advisable to follow the manufacturer's instructions and guidelines to ensure the optimal performance and longevity of your washing machine.
