Question/Problem - Cause
Cause
The multistage centrifugal pump does not turn on:
• The power cord is not plugged in or there is an
electrical breakdown;
• The water level is lower than the suction level. The
float switch is not activated;
The pump turns off suddenly:
• The thermal overload relay has switched off the pump
due to overheating;
The device starts but does not pump any water:
• The suction hose is bent or clogged;
• The suction tube is clogged with debris;
The pump automatically shuts off after it has only been
running for a short period of time:
• The thermal overload relay (motor protector)
switches it off due to excessive dirt in the water;
• The temperature of the water is too high, so the
overload relay turns it off;
Solution
• Check the plug, socket and circuit breaker of the supply
circuit;
• The water level must be higher than the suction level;
• While letting the pump cool down, unplug the power
cord and clean the impeller;
Do not let the temperature of the water exceed 35°C;
• Insert the hose correctly and clean it;
• Remove the debris;
• Unplug and clean the pump and the well;
• Do not let water temperature exceed 35°C;
