MALFUNCTION CHECKING (possible reasons) SOLUTION
After starting, the engine
is not turned on and there
is no sound. The supply socket is not under voltage. Check the electricity supply.
The engine of the pump is not under voltage. Check the supply cable to the pump.
Check protection. If the circuit breakers are defective replace
them with new ones.
Potential intervention of thermal protection Wait for approximately 20 mins for cooling
engionet. Check the reason which caused it
and remove it.
NOTE: A repeat of the failure means that there
is short-circuit of the engine.
After starting, the engine
does not turn but there is
a sound. Low supply voltage. Check the supply voltage.
Search for any blocking of the pump or engine. Remove any mechanical resistance.
Check whether the shaft is blocked. Remove the cap using the tool and turn the
shaft with a screwdriver.
Check the condition of the condenser. Replace the condenser.
The engine has diffi culty
running. Make sure that the supply voltage is suffi cient. Check the supply voltage.
Check any abrasion between the movable
and fi xed components. Try to remove the reason for abrasion.
The pump does not
supply any water. The pump was not correctly fi lled. Fill the pump with water and pay attention to
any leaks of air by unscrewing the de-aerating
closure.
The suction tube has a suffi cient diameter. Replace the tube with another with a larger
diameter.
The pump does not suck
up the water. Suction of water through the suction tube. Remove the mentioned negative phenomenon
by checking the tightness of the joints and
refi lling.
A poor slope of the suction tube supports the
creation of air bubbles. Check the slope of the tube.
The pump is pumping
an insuffi cient volume
of water. The suction tube is blocked. Clean the suction tube.
Running wheel is worn or blocked. Remove the blockage or replace worn
components.
The diameter of the suction piping is
insuffi cient. Replace with piping with a larger diameter.
The pump vibrates and is
noisy when running. Check that the pump and piping are fi rmly
fi xed. Secure any loose parts.
Cavitation in the pump. Decrease the height of the suction or check
the decrease of pressure.
The pump is overloaded. It could be useful to restrict the infl ow.
