Daan Tech Bob 2020 - Formation of foam inside the tank during a cycle.

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).
