Reason
1. Sensor malfunctions;
2. Motor rotates in
direction;
3. No water intake / insufficient
water intake;
4. There is air in the pump
1. Abnormal pressure sensor;
2. The parameter is set for too
low values
1. Water level of the pool is too
low;
2. Water level switch line is
abnormal;
3. Water level switch type is set
correctly
1. Water tower floating
failure
1. Sensors are not connected;
2. Sensor wiring error;
3. Sensor open;
4. Sensor damage;
5. The open circuit detection
value is set to be too large
1. Speed up too fast;
2. Damaged power electronic
components;
3. Interference caused
misaction;

Solution
 Check whether
sensor is normal;
reverse  Check whether the motor steering
is correct;
 Check whether the parameter
b00.09 is set for too large value;
 Check that the water pump does
not drain the internal air
 Check whether
sensor is normal;
 Check whether the parameter
b00.08 is set for too small value
 Check the water inlet system;
 Check the wiring of the water
level switch and the terminal S1;
 Check whether the b00.21 settings
match the water level switch type
ball
 Check the floating ball
 Check the
between the sensor and the
controller;
 Check whether the sensor is
normal;
 Check if b00.13 is set up too large
 Extend the acceleration time;
 Check whether there is any strong
interference around it;
