QUICK TIPS FOR REMEDYING
FAULTS
The unit isn't working
• Check the mains voltage, the fuse and the ground fault cir-
cuit interrupter. Replace defective fuses only with fuses
with the same nominal value! If the fuse triggers again, call a
qualified electrician or our customer support service.
• The internal 2 A glass tube fuse (delay) for the 230/12V con-
trol transformer, the motor contactor and the 230V AC pow-
er supply are faulty. Replace defective fuses only with fuses
with the same nominal value!
• If the mains cable is damaged, it may only be replaced by the
manufacturer.
• If the float switch is obstructed, close the inlet shut-off
valve, open the maintenance cover and clear the blockage.
If the alarm is triggered and the unit does not work:
• The thermostat in the motor windings may have switched
off the system because the pump is obstructed. In this case,
close the shut-off valve at the inlet, drain the tank, pull out
the mains plug, remove the pump module, and clear the
blockage.
Decreased pumping performance
• Check that the shut-off valve in the pressure pipe is fully
open.
• If the pressure pipe is blocked, flush water through the pres-
sure pipe to clear it.
• If the non-return valve is blocked, empty the pressure pipe
and clean the non-return valve.
• If the ventilation system is blocked, clean the ventilation
hose that leads from the pump tank and check the drilled
holes.
• If the unit works normally when it starts pumping, but be-
comes very loud towards the end, then a qualified electrician
must redefine the switch-off point in the control unit.
Indicator "Drehfeld falsch" (Wrong rotating field) lights up
• Mains phase sequence is wrong or phase is absent - thus
lower or absent pump delivery. The mains connection must
be corrected by a qualified electrician only.
Indicator "Störung Pumpe" (Pump failure) lights up (not
compli 300)
• The pump is protected by an integrated circuit breaker which
switches off the pump if it overloads or if there is an electric
motor fault. After this has been triggered, the control unit
has to be opened by a qualified electrician in order to press
the reset button.
Indicator "Hochwasser" (High water) lights up (not compli
300)
• Water level in the tank too high because of low pump flow
rate or excessive inflow. Remove any obstructions in the
pump or pressure pipe and/or eliminate the excessive inflow.
LED P1 on the analogue evaluator is permanently lit up (not
compli 300)
• There is a fault in the level monitoring. Call our customer
support service.
• There is no water left in the tank. Fill with a small amount of
water.
• Note: If the LED lights up briefly after the pumping opera-
tion, this is not a sign of a malfunction.
Pump "snores" and does not switch itself off (not compli 300)
• The switch-off point of the unit is too low.
Unscrew the three fixing screws on the level monitoring at the
front of the collecting tank. By carefully rotating it to the right
the switch-off point can be set to a higher level. Retighten the
screws. The switch-off level is reached during pumping when
the LED2 goes off.
NOTICE! It may also be necessary to re-adjust the switch-on
level (please refer to the section "Redefining the switch-on le-
vel").
