Cause
Solution
Safety adapter lever position
not correct.
Check lever setting and adjust.
Safety adapter soiled.
Remove safety adapter; open shut-off lever and clean openings with
cleaning brush (Order No. 4006570).
Hose installation.
Check that there are no kinks or marked narrowing of cross-section.
...Filter performance has greatly deteriorated
Hose installation soiled
Clean hose installation at regular intervals by drawing a universal
cleaning brush (Order No. 4006570) through the suction channels
and pressure channel or suction pipes and nozzle tube.
Strainer blocked.
Remove coarse dirt, clean strainer.
Filter media heavily soiled.
Clean
fi
lter media.
Filter media
fi
lled into a net
bag.
Never put long-term
fi
lter media in net bags or nylon stockings. This
leads to a drastic reduction in pump performance within a short time.
Filter media not cleaned
properly.
When cleaning, remove the
fi
lter media from the
fi
lter media basket
and rinse through with lukewarm water.
Filter media wrongly
assembled.
Check that
fi
lter media have been assembled in the recommended
layers for
fi
ltering. Fill bottom
fi
lter insert to just under edge with
EHEIM MECH. Fill next two
fi
lter inserts with SUBSTRAT, also to just
under edge. Never place white
fi
lter pad under the handle.
Filter pad inserted wrongly.
After inserting the top
fi
lter insert, push in the handle and lay the
white
fi
lter pad on top.
Filter pad not renewed.
Be sure to renew the
fi
lter pad each time you clean
(Order No. 2616805).
Pump is dirty.
Clean pump chamber, cooling and lubrication channel with cleaning
brush set (Order No. 4009570) (see chapter on Servicing and
Maintenance).
Water is not circulating
properly.
Take
fi
lter into operation by priming (as described in the instructions).
Make sure that the water runback (delivery side) is above the surface
of the water during
fi
lling so that air is optimally bled from the device.
Too many accessories
installed on the hose
system.
Connected accessories reduce
fi
lter performance. Check and
remove unnecessary accessories or operate via a separate water
circulation system.
Cause
Solution
No mains supply.
Plug in to mains.
Shaft broken.
Renew shaft (see list of spares).
Impeller missing or blocked
by bits of gravel, shells or
similar.
Fit impeller, clean pump chamber.
