Cause

Low water protection system did not react

External Off

Intake pressure above pressure setpoint

Controller fuse faulty

Motor protection switch for the pumps has triggered

No mains voltage

Main switch “OFF”

Operating mode of the pumps “OFF”

Non-return valve leaking

Operating mode of the pumps “Manual”

Pressure setpoint set too high

Gate valve to pressure transducer closed

Gate valve in the system closed

Insufficient bleeding of the pumps

Error message pumps/frequency converter faulty

Intake pressure fluctuates severely

Diaphragm vessel closed or filled incorrectly

Volume flow too high

Suction-side pressure switch faulty or connected incorrectly

Check controller parameters

Check dry-running protection follow-up time T1

Check zero-flow follow-up time T2

8.3

Error memory for faults

The last 9 faults that occurred and the current 
fault are displayed in the form of fault numbers 
(code numbers) in the Error memory menu (see 
Menu structure).

The error memory is designed in such a way that 
the oldest fault (fault F9) is lost when a new fault 
applies and is saved.
If F0 is displayed in the first menu item, a fault cur-
rently applies, which is characterised by its fault 
number.

Code no.

Cause

Remedy

Low water/dry running

Check intake pressure/water level of break tank

E40

Sensor faulty

Replace sensor

E42

Sensor cable faulty

Replace/repair sensor cable

E60

Overpressure

Consult Wilo Service

Software stack low

Consult Wilo Service

E73

Internal electronic supply voltage too low

Check mains connection, consult Wilo Service

E75

Hardware analogue output faulty
