Advise customer that due
to plastics having a low
thermal mass, these items
give inherently bad drying
performance.
Go to Question 3,
Advise customer that
due to lower final rinse
temperatures, dry
performance is comprised
when using Fast and Eco
cycles (there is less residual
heat for drying at the end
of cycle).
Go to Question 5.

the external vent may cause a mist on the floor, and in
extreme cold ambient conditions water can drip from
the external vent.
