The device has an appliance to notice a little permanent water loss, for example
leaking lines or connectors and shut down the pump. If the automatic garden
pump switches in/off in short times again and again, it recognizes a leakage. The
pump switch to Error (red LED "Fehler" (Error) lights up) and the blue pressure
light runs permanent from the top to the bottom. In this case, you should check
all connections and lines. Also check the check valves, if they are dirty. After
solve the problem, press the "ON / Neustart" button to start the pump again.
Please note, that this protection can only note little leakage. It doesn´t
switch off, if there is for example a water pipe is broken. A big leakage
won´t be detected, because the pump indicates a normal use.
If only a very low flow rate is constantly conveyed (less than 400 l/h), this can be
interpreted by the electronics as a leakage and after switching off and on 10
times (see above), the device switches to „Fehler".
If such operating conditions exist, it is possible to switch off the leakage protec-
tion function and operate the device without leakage protection.
To do so, proceed as follows:
- With the device switched off (STOP button pressed), press and hold the
"ON / Neustart" button for at least 5 seconds.
- The green/orange LED "ohne Tank" mode indicator light starts to blink con-
tinuously, indicating that the leakage protection is deactivated.
Activating leakage protection
- With the device switched off, keep the "ON / Neustart" button pressed for
at least 5 seconds.
- The LED "ohne Tank" mode indicator light now illuminates green/orange
continuously
- This indicates that the leakage protection is activated (factory setting).

9. Maintenance and troubleshooting
Prior to carrying out any maintenance work, the pump must be sepa-
rated from the electrical mains. If you fail to separate the unit from
mains, there is a risk of an inadvertent start of the pump.
We decline any liability for damage caused by inappropriate repair at-
tempts. Any damage caused by inappropriate repair attempts will avoid
all warranty claims.
Regular maintenance and thorough care will reduce the danger of possible malfunc-
tion and contribute to an extension of the lifetime of your unit.
