9. Fault finding

DANGER
Electric shock

Death or serious personal injury
- Switch off the power supply before starting any

work on the product. Make sure that the power
supply cannot be accidentally switched on.

CAUTION
Pressurised system

Minor or moderate personal injury
- Before dismantling the pump, drain the system or

close the isolating valves on either side of the
pump. The pumped liquid may be scalding hot
and under high pressure.

Fault

Control panel

Cause

Remedy

1. The pump does not

run.

Light off.

a) One fuse in the installation is blown. Replace the fuse.
b) The current-operated or

voltage-operated circuit breaker has
tripped.

Cut in the circuit breaker.

c) The pump is defective.

Replace the pump.

Changes between "- -"
and "E 1".

a) The rotor is blocked.

Remove the impurities.

Changes between "- -"
and "E 2".

a) Insufficient supply voltage.

Check that the supply voltage falls within
the specified range.

Changes between "- -"
and "E 3".

a) Electrical fault.

Replace the pump.

Changes between "- -"
and "E 4".

a) Dry-running protection.

Make sure that there is sufficient liquid in
the pipe system. Reset the error by
pressing any button or switch off the
power supply.

2. Noise in the system.

Shows a number.

a) Air in the system.

Vent the system.
See section

5.3 Venting the heating

b) The flow is too high.

Reduce the suction head.

3. Noise in the pump.

Shows a number.

a) Air in the pump.

Let the pump run. The pump vents itself
over time.
See section

5.2 Venting the pump

b) The inlet pressure is too low.

Increase the inlet pressure, or check the
air volume in the expansion tank, if
installed.

4. Insufficient heat.

Shows a number.

a) The pump performance is too low.

Increase the suction head.
