Malfunction
No flow of water
Water flow insufficient
Water remains cloudy
Unusual noises in the drum
Rinsing channel blocked
Filter drum is partially
soiled, cannot be cleaned

emergency overflow.
Time-dependent cleaning
function (interval) does not
start

Possible cause
Filter pump not switched on.
Supply to filter system or return to pond
blocked.
Bottom drain, pipe or hose blocked
Hose kinked
Excessive loss in lines
Insufficient pump capacity
The water is extremely soiled.
Dirt particles are not reaching the Drum Filter
Module.
Too many pond animals
Screen elements clogged or damaged
Drum seal incorrectly positioned
Drum seal is damaged
Large dirt particles have collected in the filter
drum
Large particles of dirt such as string algae
are blocking the dirt channel.
Rinsing nozzle clogged
Screen elements clogged
Pump capacity too high
The pipe of the dirt outlet is blocked.
The control system checks the function of the
level detection device.
• This check is started automatically if too
few automatic cleaning procedures have
been carried out.
Cable not connected
Control system has switched off due to
overheating (temperature switch)
Safety fuse has tripped due to a blockage of
the rinsing pump (excessive current
consumption)
Harmless food-grade oil may leak from a
new rinsing pump for a short time when first
used
Insufficient Hel-X biomedia used
Unit has only been in operation for a short
time.
Remedy
Switch on the filter pump, connect the power plug.
Clean the supply and/or return.
Clean, replace if necessary.
Check hose, and replace if necessary.
Reduce line length to necessary minimum.
Adjust the pump capacity accordingly
• Remove algae and leaves from the pond.
• If the water is particularly contaminated, change
30 % of the water to avoid damage to the fish.
• Optimise the water flow so that the skimmer
and/or the filter pump can draw in the dirt
particles.
• Align the skimmer and/or filter pump in relation to
the water flow so that they can draw in dirt
particles.
Reduce number of pond animals
Clean or replace screen elements
Check the seating of the drum seal
Replace the drum seal
Remove a screen element and remove dirt
particles from the filter drum
Remove a screen element and clean the dirt
channel.
Clean the rinsing nozzle, replace if necessary
Clean/descale the screen elements
Reduce the pump capacity.
Clean the pipe
• Wait. The check takes a maximum of 24 hours.
• The check is completed once the level detection
function is triggered. An automatic cleaning
procedure is carried out.
• If the level detection device is not triggered within
24 hours, Er22 is displayed. The time-dependent
cleaning cycle is activated. (→ System
messages)
Check cable connection
Protect the control system from heat and allow it to
cool down.
• The control system will switch back on
automatically when it has cooled down.
• Error message Er66 gives a warning before the
control system overheats.
Clean the rinsing pump(→ Cleaning the rinsing
pump)
Replace the fuse (→ Technical data)
No measure is necessary
Use more Hel-X biomedia if necessary.
The full biological cleaning effect is only achieved
after several weeks.
