11. FAULTS, CAUSES AND SOLUTIONS
When a situation occurs that prevents the normal operation of the pump, the pump
automatically stops and gives an error or warning code.
See Figure 7.1. Thanks to the codes written on the screen, the cause and solution of
the error can be learned. See. Table 11.1.
1) After an error / warning occurs, the pump switches to standby for 5 seconds. It starts again.
2) If the reason for the error / warning disappears after waiting for 5 seconds, the pump starts working again. If the
reason for the error / warning continues, the
pump gives an error / warning again.
3) Error / warning code is found in "P40" in the program menu of the pump.
4) All errors are stored in "P40", the last (20) errors.
If the pump fails, it cannot be restarted, service intervention is required.
