Fault/ Cause/ Remedy - Grohe Tectron 38 386 Anleitung

IV. Sensor element
1. Loosen screw (D1) and push sensor bracket (D)
downwards, see Fig. [3].
2. Disconnect plug-in connector between sensor cable (E1)
and electronic module (A), see Fig. [15].
3. Disengage sensor (E) at the bottom and detach from
bracket (D), see Fig. [4].
Assemble in reverse order.
Disconnect and reconnect plug-in connector between
electronic module (A) and transformer (H), see Fig. [11].
After reconnecting power supply, position detection begins.

Fault/ cause/ remedy

Fault
No flushing
Water flowing continuously
Undesired flushing
Flow volume too low
Flow volume too high
Position detection is not
performed (No flushing)
V. Sensor for wall installation
1. Disconnect plug-in connector between sensor cable (E1)
and electronic module (A), see Fig. [16].
2. Close isolating valve (B), see Fig. [8].
3. Remove urinal.
4. Turn retaining tabs (K) and remove sensor (E), see Fig. [6].
Assemble in reverse order.
Disconnect and reconnect plug-in connector between
electronic module (A) and transformer (H), see Fig. [11].
After reconnecting power supply, position detection begins.
Replacement parts, see fold-out page I
( * = special accessories).
Cause
• Water supply interrupted
• Filter in solenoid valve blocked
• Plug-in connector without contact
• The detection zone of the sensor system
is set too low/too high
• Solenoid valve defective
• Transformer faulty
• Software lock activated because
compensation routine has been
performed 25- times
• Electronics defective (indicator lamp
not flashing or permanently on)
• Solenoid valve defective
• The detection zone of the sensor system
is set too high
• Flow volume set too low
• Filter in solenoid valve defective
• Filter in solenoid valve blocked
• Solenoid valve defective
• Flow volume set too high
• Solenoid valve defective
• Replacement part exchanged,
no position detection
• Software lock activated because
compensation routine has been
performed 25- times
Remedy
- Open isolating valve
- Clean or replace filter, see Solenoid
valve and filter maintenance
- Attach plug-in connector
- Increase/reduce range, see Settings,
Setting the range
