Is the excelle washing accelerator broken?

Hello, dear! It doesn't matter if the power is off. The key point is, 1, if the throttle is continuously powered to wipe, it does not need to be initialized after washing, and cold car washing and hot car washing can be done; 2. If it is disassembled and cleaned without power supply, it must be initialized after completion. I hope my answer can help you, please set it as the best answer, thank you!
