Troubleshooting
No function (no water)
Test
Procedure
Result
Measure
1. Test power supply
Remove power supply plug
to e-module and put back in
again
1. 2x signal OK, proceed to test 2
2. No signal - no power supply
Test fuse, replace mains
connection/batteries
2. System diagnosis
Bring magnetic contact to
contact field; wait for 4x si-
gnal (approx. 4 s)
Remove magnetic contact 2x
signal = confirmation
After 10 s flush followed by
1x signal = OK
1x signal without flush, Test:
1. E-module connection-solenoid valve
2. Water supply
3. Solenoid valve
2x signal = sensor error, Test:
1. E-module connection-sensor
2. Sensor
3. E-module
3x signal = weak batteries
Open isolating valve
Replace solenoid valve
Replace sensor
Replace e-module
Replace batteries
Continuous flow

sories)
Plug in function tester at plug-
in contact to solenoid valve.
Activate sensor by powerful
