11. Troubleshooting
Problem Cause Remedy
SG150 and SG150D
Drips During the heating up of the water
heater no error, normal function
Continually drips from soiling Actuate lifting grip multiple times so that dirt
particles are flushed out, or replace as
necessary
Backflow stopper does not close
off tightly in the front pressure
area. Pressure increase in the front pres-
sure area Replace backflow stopper
Seal surfaces dirty or worn Replace backflow stopper
Too little or no water pressure Cut-off fixtures before or after the
safety group not opened entirely
Open the shutoff valves fully
Safety group not installed in the flow
direction Install safety group in flow direction
(observe arrow direction on housing)
only SG150D
Water is escaping from the
spring bonnet
Diaphragm in valve insert is faulty Replace valve insert
Too little or no water pressure Pressure reducing valve is not set to
the desired outlet pressure
Set outlet pressure
Filter in pressure reducing valve is
contaminated Clean or replace filter
The outlet pressure set does not
remain constant Filter in pressure reducing valve is
contaminated or worn Clean or replace filter
Valve insert, sealing ring or edge of
nozzle is contaminated or worn Replace valve insert
Rising pressure on outlet (e.g. in
boiler) Check check valve, safety group etc.
Expansion water from the hot water
purifier Inspect backflow stopper before the hot
water purifier and single-lever mixing valve
if necessary.
Close shut-off valves to the hot water puri-
fier supply line. Open hot water tap connec-
tion. Does pressure remain constant?
Expansion water of the hot water purifier.
Does pressure increase? Pressure reducer
defect.
