low, foam filters are not com-
pletely immersed in water.
22
Possible cause
Sensor soiled
No dirty water, cleaning is not
necessary
Filter pump is not operating
Control device incorrectly posi-
tioned
Control device defective
Insufficient conductivity of the
water
Insufficient pump capacity
ScreenMatic screen soiled
Sensor soiled
Control device incorrectly posi-
tioned
Pump capacity too high
Motor cable plug not connected
or incorrectly connected to the
control device
Motor defective
Connection cable plug not con-
nected or incorrectly connected
to the transformer
Transformer not connected to
the mains voltage
Transformer defective
Control device defective
Possible cause
Filter pump not switched on
Supply to filter system or return to pond blocked
Hose kinked or clogged
Excessive loss in the hoses due to friction
Insufficient pump capacity
Insufficient circulation of the water
The water is extremely soiled.
Too many pond animals
ScreenMatic screen is clogged
Foam filters soiled
Pond inlet blocked
Filter pump is not operating.
The water level is initially lower when new foam fil-
ters are fitted as they have not yet been colonised
by bacteria.
The separating plate is missing.

Remedy
• Clean the sensor.
• Descale the sensor.
–
Start up the filter pump.
Correctly position the control de-
vice
Replace the control device.
Increase the water hardness with
OptiPond
Adjust the pump capacity accord-
ingly
• Start manual the cleaning cycle
and use a brush to clean the
ScreenMatic screen on the side
of the water distributor
(→ Manual cleaning)
• Clean the ScreenMatic screen
from the inside if the mesh is
clogged by a biofilm
(→ Cleaning/replacing the
ScreenMatic screen)
Clean the sensor.
Correctly position the control de-
vice
Adjust the pump capacity accord-
ingly

Connect the transformer to the
mains voltage.
Replace transformer
Replace the control device.
Remedy
Switch on the filter pump, connect the power plug
Clean the supply and/or return
Check, clean or replace the hose if necessary.
Reduce hose length to reduce frictional loss
Adjust the pump capacity accordingly
• Adjust the pump capacity accordingly
• Optimise the circulation of the water in the pond.
• Remove algae and leaves from the pond.
• Change the water.
• If the water is particularly contaminated, change 30% of
the water to avoid damage to the fish.
Reduce number of pond animals
Guide value: approx. 2 ft (60 cm) fish length per 265 gal (1
3
m
) pond water
Clean or replace the ScreenMatic screen.
Clean foam filters
Clean the pond inlet.
Start up the filter pump.
• It takes several weeks for the bacteria to become estab-
lished and the foam filters to become fully effective.
• Use OASE filter starter Biokick to speed up the coloni-
sation of bacteria.
• Insert the separating plate.
