Lengthy
periods
out

a
fairly
long
period
of

crystallisation
and
damage
to
the
pumps:
remove
the
intake
hoses
from
the
detergent
and
rinse
aid
containers
and
place
them
in
a
container
of
clean
water,
then
perform
a
few
wash
cycles
followed
by
a
complete
pump
‐
out.
Finally,
turn
off
the
master
switch,
close
the
water
intake
valve
and
leave
the
door
ajar
until
the
interior
is
completely
dry.
The
detergent
and
rinse
aid
intake
hoses
must
be
put
back
into
the
containers
when
the
warewasher
is
returned
to
service,
taking
care
not
to
swap
them
over
(red
hose
=
detergent,
blue
hose
=
