14 2 Fault during operation
Fault Cause Remedy
Low regenerative indicator is
shown.
Insufficient regenerative in the
regenerative container ( 3 ).
Refill the regenerative (see
chapter “11.5.3 Refilling operating
materials”, page 49).
If there is still regenerative in the
container, regenerative encrus-
tation may have formed under
the ultrasound sensor.
Loosen and stir the regenerative.
The product is not supplying
softened water.
No regenerative in the regenera-
tive container ( 3 ).
Refill the regenerative (see
chapter “11.5.3 Refilling operating
materials”, page 49).
Manually initiate regeneration for both
exchanger columns, one at a time.
Power supply interrupted. Establish electrical connection.
Blending not set correctly. Set blending (see section
“Setting the water hardness”
on page 46).
A cavity prevents enough
brine from being formed (“salt
bridge”).
Ensure that the regenerative is
filled evenly without cavities. If the
regenerative level is low, “stir” the
regenerative with a suitable object.
The product supplies deviating
outlet water hardness.
The product has not been finely
adjusted.
The outlet water hardness still has
to be finely adjusted.
Water hardness of the inflow
water has changed.
Adjust the water hardness of the
inflow water.
The product is not supplying
softened water or the flow is
insufficient.
Inlet pressure is too low. Increase inlet pressure (set pres-
sure reducer if necessary) and
start manual regeneration.
Coloured rinsing water at
start-up.
Abrasion particles from ex-
changer resin are flushed out.
Start-up repeat rinsing (see
section “Rinsing procedure”
on page 26).
An implausible fill level is
displayed.
The regenerative container is
filled past the 100% mark.
Remove any excess regenerative
so that the regenerative container
is filled up to the 100% mark at
most.
The product cannot be reg-
istered.
The product cannot be con-
nected to a network.
The product cannot be added to
the BWT Best Water Home app.
Lack of connectivity. Check for faults during start-up
(see chapter “14.1 Fault during
start-up”, page 67).
If the cause cannot be found,
contact after-sales service (see
chapter “15.1 Product returns”,
page 71).
If the fault cannot be remedied by following these instructions, contact our after-sales service department.
You will need the serial number and production number, which can be found on the type plate of the Easy Fill technology cover
Keep these numbers handy when you contact after-sales service.
