Issue Possible causes Known solutions
Bob does not turn on.
A fuse has blown in your
electrical system or the
circuit breaker has tripped.
Unplug all other appliances
connected to the same electrical
circuit as Bob. Replace the fuse
or reset the circuit breaker.
The power supply is not
activated.
Check that the power cord is
properly plugged at both ends
into either the wall outlet or at
Bob’s side.
The cycle does not start.
Bob cassette is missing
(empty or full).
Insert a Bob cassette (emptpy
or full).
The door is open. Close the door.
The door remains open,
impossible to close it.
Check whether something
is blocking the closing of the
door. If it is not the case, please
contact the After Sales Service.
No water or not enough
water in the tank.
If you are in the “integrated tank”
mode: fill the tank up until the
signal sounds.
If you are in the “water supply”
mode: check your installation
(tap open, sufficient pressure).
The screen is frozen and
the buttons no longer
respond.
Wait 3 seconds until Bob
has started. If the screen is
still frozen, disconnect and
reconnect Bob.
Water does not drain out
of Bob.
The drain hose is bent.
Check the drain hose and fix it
with “Bob Easyfix”.
The water outlet is blocked
(under the filter).
Clean the bottom of the interior
and the filters.
The drain hose is blocked
by a foreign body/material.
Contact the After Sales Service.
Issue Possible causes Known solutions
Formation of foam inside
the tank during a cycle.
Inappropriate detergent.
Only avoid special dishwasher
detergent to avoid foaming.
However, if this happens, open
the dishwasher door and allow
the foam to evaporate. Close the
door and start a wash program
to drain the water. Repeat the
procedures if necessary.
Soil that generates foam.
Different types of soil generate
more or less foam. However, if
there is too much foam during a
cycle it can block the spray arm.
In this case, empty the basket
and run an empty cycle before
you start washing your dishes
again.
Stains on interior surfaces.
Limescale may appear on
the surfaces.
Run a maintenance cycle at
least once every 90 cycles with
a rock'n'roll cassette (refer to
page64)
I live in an area with very
hard water.
Run a maintenance cycle with
a rock'n'roll cassette more
frequently (every 30 cycles).
