Maintenance - Grohe Essence E 36 089 Handbuch

Automatic safety shut-off
After 60 s (factory setting) of continuous detection of an object,
the infrared electronics automatically stop the water flow.
Automatic flushing (factory setting: not activated)
Automatic flushing serves to ensure water hygiene in the event
of long-term non-utilisation of the fitting. and activates water
flow for 1 - 10 minutes, 1 or 3 days after the last use.
Safety notes:
- Ensure free draining in the case of activated automatic
flushing.
- For automatic flushing of the hot and cold water lines, the
fitting must be in the mixed water setting.
Cleaning
For cleaning purposes, the fitting can be switched off by
attaching the enclosed cleaning clip (M), see Fig. [9].

Maintenance

Shut off the hot and cold water supplies and switch off the
voltage supply.
Inspect, clean and, if necessary, replace parts.
I. Transformer
1. Interrupt the voltage supply via transformer (E), see Fig. [10].
2. Detach plug-in connector (D).
Assemble in reverse order.
II. Solenoid valve (12 V DC)
1. Remove screw (N) and detach housing (O), see Fig. [11].
2. Remove screws (P1) and detach retaining plate (P).
3. Detach plug-in connection (Q) and remove solenoid
valve (R) by turning clockwise using a 5mm allen key,
see Fig. [12].
4. Remove filter (T).
Install in the reverse order observing the installation position.
Fault/ Cause/ Remedy
Fault Cause
Water not flowing • Water supply interrupted
• Filter upstream of solenoid valve blocked
• Solenoid valve defective
• Plug-in connector of solenoid valve
without contact
• No voltage
• Hands not in reception range
Water flowing • Solenoid valve defective
continuously
Undesired water flow • Sensor system detection zone set too
high for local conditions
Flow rate too low • Filter or mousseur dirty
• Service valves not fully open
• Water supply restricted
Incorrect mixed • See "Flow rate too low"
temperature • Limescale on mixer spindle
• Temperature limiter incorrectly set
III. filter
1. Unscrew connection hose and remove adapter (C),
see Fig. [13].
2. Remove filter (B).
Assemble in reverse order.
IV. Remove and clean mousseur (13 943)
Assemble in reverse order.
V. Mixer spindle
1. Disconnect fitting from connections.
2. Remove fitting from wash basin. Disassembly is as
described in section "Setting temperature limiter",
see Figs. [6] to [8].
3. Remove screw (U) from housing using a 2.5mm allen key,
see Fig. [14].
4. Pull out mixer spindle (H, L).
Assemble in reverse order.
Screw (U) must engage in groove (H1, L1) of mixer
spindle (H, L).
Replacement parts, see fold-out page I (* = special
accessories).
