Fault description
No metering - dosing
pump rattles.
Dosage is too small.
Dosing pump does not
work.
Pump doesn't draw.
Pump head leaking.
Medium leaks from
diaphragm failure drain.
Cause
Counter-pressure too high. Reduce pressure at pressure retention
Discharge line and/or valve
blocked.
Actual counter-pressure in
equipment (= total of all
pressure losses) is too
high.
Dosage setting incorrect.
Suction line leaking.
Dosage counter-pressure
too high.
Viscosity setting incorrect.
Wrong pump head.
Operating voltage too low /
not on.
Power cord damaged.
Motor / electronics faulty.
Switched-mode power
supply (SMPS) faulty (in
230 V back cover
modules).
Suction line leaking.
Storage container empty /
fill level too low.
Air in pump head and
suction line.
Sediment, valves sticking
or blocked.
Pump head mounting
screws loose.
Diaphragm is torn.

Malfunctions / Repairs
Remedy
valve.
Disassemble and clean valve(s) and
lines on the pressure side, and clear
blockage.
Determine and calculate pressure loss of
entire system, and compare/check pump
system layout
Ä Chapter
increase output (
6.1.1 'Setting the flow rate' on page 33).
Check/service connections and suction
line, and replace if necessary.
Check actual counter-pressure (= total of
all pressure losses) and valves and lines
on pressure side - clear bottlenecks.
Check jumper position and viscosity (
Setting' on page 33).
Install correct pump head.
Check operating voltage / control.
Replace power cord.
Replace pump module (II).
Check SMPS: OK = LED lights up,
replace SMPS if necessary.
Check and service suction line and
connections, and replace if necessary.
Fill / replace storage container.
Briefly reduce dosage counter-pressure
and bleed pump.
Flush pump head via suction line;
remove and clean dispensing head, or
replace if needed.
Tighten pump head screws crosswise
(M = 3,75 Nm).
Replace pump head and diaphragm.
