The device is not switching off automatically:
•
The float switch is hindered from lowering. Check whether
the float switch can move freely. Remove any blockages or
ensure sufficient freedom of movement for the float
switch.
The device switches off after a brief runtime:
•
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.
•
Check whether the hoses are blocked and whether the
water contains any suspended matter with a particle size
of more than 5 mm, which could clog up the device. The
device might have overheated due to the blockage and the
thermal protection circuit is activated.
Insufficient or decreasing conveying capacity:
•
Check whether the hoses are blocked and whether the
water contains any suspended matter with a particle size
of more than 5 mm, which could clog up the device.
•
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.
