6. TROUBLESHOOTING
DANGER! Electric shock!
Risk of injury due to electric current.
v Disconnect the product from the mains before you
troubleshoot the product.
To troubleshoot with the error diagnosis system [ Fig. T1 ]:
The pump is equipped with an error diagnosis system which indicates
various error states via the error LED
1. Disconnect the pump from the mains.
2. Make the respective remedies from the table below.
3. Start the pump again.
The error display has been cleared and the pump is ready for operation
again.
Problem
Possible Cause
Error-LED flashes 1 time
The pump does not pump water for 30 seconds during the
(with a 2 second break)
initial operation.
Pump does not suck water
Pump was not sufficiently
filled with liquid to be pumped.
Air cannot escape on the pres
sure side, because the pressure
side outlets are closed.
Pump does not start
The pump housing has heated
up and the thermal circuit brea
ker has been activated.
The impeller is blocked.
Only for Art. 1758:
The flow sensor is dirty.
Flow sensor signal is faulty
Error-LED flashes
The pump does not pump water for 6 minutes during the
2 times (with a 2 second
initial operation.
break)
Pump does not suck water
Problem on the suction side.
Suction hose deformed or bent. v Use a new suction hose.

Remedy
v Fill the pump and make sure
that water does not drain out
on the pressure side during
the suctioning process
(see 3. OPERATION).
v Open the pressure side
outlets (see 3. OPERATION).
1. Open possible shutoff device
in the pressure line (release
pressure).
2. Ensure sufficient ventilation
and let the pump cool down
for 20 min.
1. Loosen the impeller (see
"To loosen the impeller").
2. Let the pump cool down for
20 min.
v Clean the flow sensor (see
"To clean the flow sensor").
v Immerse the suction hose
end under water.
v Eliminate any leak on the
suction side.
v Clean the check valve on
the suction line and check
the installation direction.
v Clean the suction filter on the
suction hose end.
v Clean the filter lid seal and
turn the lid until the stopper
(see 4. MAINTENANCE),
v Clean the filter in the pump.

To loosen the impeller [ Fig. T2 ]:
If the impeller is stuck due to dirt, the Error LED flashes 1 time
(with a 2 second break).
(16)
1. Turn the motor shaft
with a screw driver.
This will loosen the blocked impeller.
2. Start the pump (see 3. OPERATION).
Only for Art. 1758: To clean the flow sensor [ Fig. T3 ]:
If the flow sensor is stuck due to dirt, the Error LED flashes
(with a 2 second break).
1. Loosen both screws

(18)
2. Remove the cover
.
3. Loosen the screw
(19)
and remove the clip
(21)
4. Loosen the cap
