10 EN deep well pump TDP 370 E / TDP 750 E
The device is running, but not pumping any water:
• Check whether the dirt strainer ( 4 ) is clogged. Remove any
obstructions.
• Check whether the water level is too low or the device is
not completely submerged. If necessary, submerge the
device deeper into the water.
• Check whether the used hose diameter is too small.
• Check whether the hose line is kinked or blocked. Remove
kinks and / or blockages.
The device switches off after a brief runtime:
• Check the water for dirt. If the water is too dirty, the device
will become hot and the thermal protection circuit will
switch the device off.
• Check whether the water temperature is too high. The
device might have overheated due to a too high water
temperature and the thermal protection circuit is activated.
• Check the power connection.
• Check the power cable and mains plug for damage.
• Check the on-site fusing.
Insufficient or decreasing conveying capacity:
• Check whether the dirt strainer ( 4 ) is clogged. Remove any
obstructions.
• Check the hose diameter and the delivery head. An
excessive delivery head paired with a small hose diameter
can cause a reduction of the conveying capacity.
• Check whether the hose line is kinked or blocked. Remove
kinks and / or blockages.
Note
Wait for at least 3 minutes after maintenance and
repair work. Only then switch the device back on.
