Float of the level sensor is stuck.
Push the level sensor float carefully up/down until it
is at permeate level.
Defective level sensor.
Replace level sensor.
External stop signal on the TP-pump.
Read the conductivity meter; if this is >20 μS/cm it
will result in an external stop signal. Re-establish the
permeate quality; see chapter 9.2.2 in the RO-
manual.
The thermal fuse in the TP-pump is turned
off due to overheating.
Turn switch to OFF, let the TP-pump cool down and
turn the switch back on ON
Error 3:
TP-pump is
running but
no permeate
is getting to
the consumer
Air in the TP-pump.
Turn switch to OFF, fill up the TP-pump with
permeate and turn switch back to ON. Let the pump
run a while with a large flow in order to get the
remaining air out of the pump case.
Low water level.
Disconnect the consumer. Let the BWT AQUA Flex
reservoir become completely filled and the TP-pump
will start automatically.
The motor of the transport pump is
running in the wrong direction.
Check the wiring diagram of the BWT AQUA Flex
reservoir and make a correct connection.
Error 4:
TP-pump
starts and
stops
If the piping connection is too small there
is a risk of outages on the plant due to
lacking water pressure/amount etc.
Replace the permeate outlet pipe with an outlet pipe
with a larger dimension.
Non-return valve is leaky/defective
Replace the non-return valve
The hydrophore is defective or lacking
air.
Replace the hydrophore and set the pre-pressure at
2.7 bar.
The hydrophore capacity is too small.
Contact BWT for technical advice.
Pressure switch set incorrectly.
Set the pressure switch to 4.0 bar (Stop) and 3.0
bar (Start).
Error 5:
The quality of
permeate is
higher than
20 μS/cm
Leaks around the BWT AQUA Flex
reservoir and/or impurities inside the
reservoir.
Empty the BWT AQUA Flex reservoir completely
and repair the leaks. Fill up with permeate
<20 μS/cm
from the RO-unit.
