Question/Problem - Cause
Cause
The pump won't turn on:
• The power cord is not plugged in or there is an
electrical fault;
• The water level is lower than the level of the pump
suction. The float switch is on;
The pump turns off suddenly while it's working:
• The heat sensor shut the pump down because it was
overheating;
The pump starts but does not pump any water:
• The water outlet hose is bent or clogged;
• Air is blocking water from being taken in;
• The suction base is clogged with debris;
• The water level is lower than the level at which the
pump is applying suction;
The pump does not turn off:
• The float switch is stuck and is unable to drop along
with the water level;
Not enough water is being transported:
• The suction base is clogged with debris;
• The pump's power is reduced due to the water being
extremely dirty and mixed with abrasive substances;
The pump automatically shuts off after it has only been
running for a short amount of time:
• The protective feature installed within the motor
shuts it off due to the water being excessively dirty;
• The temperature of the water is too high so the
engine's internal protection turns it off;
Solution
• Check the plug, socket and circuit breaker of the supply
circuit;
• The water level must be higher than the level at which
suction is taking place;
• While the pump cools down, unplug the power cord
and clean the turbine;
Do not let the temperature of the water exceed 35°C;
• Insert the hose correctly and clean it;
• When inserting the pump into water, it should be tilted
slightly to ensure water enters the turbine chamber. If
necessary, tilt the pump backwards and forwards
several times until no more air bubbles appear;
• Clean up debris out of the filter;
• Lower the pump;
• Release the float switch so that it is able to maintain its
position on the water level;
• Clean up debris out of the filter;
• Clean the pump and any worn parts;
• Remove the plug from the electrical outlet and clean
the pump and well;
• Do not let the temperature of the water exceed 35°C;
