6. Assemble the filter again in reverse order.
7. Start the pump (see 3. OPERATION).
To clean the check valve [ Fig. M3 / M4 ]:
CAUTION!
The pump must not be operated without the check valve.
1. If applicable, close all the shut-off devices on the intake side.
2. Open all tapping points so that the pressure escapes on the pressure
side. Now close the tapping points again so that the connected pipes
do not drain via the pump.
(14)
3. Loosen the cover of the check valve with a suitable tool.
4. Remove the check valve (15)
5. Assemble the check valve

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
initial operation.
(with a 2 second break)
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

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.

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.
v Use a new suction hose.
v Let the pump cool down
for 20 min.
v Immerse the suction hose
end under water.
v Eliminate any leak on the
