If you encounter an issue where the motor is not working, we recommend following these steps. First, ensure that the power is turned on. Next, use a pressure regulator to check the water inlet pressure. We advise keeping the inlet pressure below 0.8 MPa, which is equivalent to 116 PSI. After checking and adjusting the water inlet pressure, please try turning on the power button again to see if the motor starts working. If the problem persists, please don't hesitate to contact us for further assistance. We are committed to resolving any issues you may encounter and ensuring your satisfaction with our product.
