Rapid advance

Whole steps in programs can be skipped
using rapid advance.

•

Press and hold the START button until
the program indicator LEDs have mo-
ved past the program steps you wish to
skip.

Program end

After final extraction, the LED by the
"doorlock delay" comes on. This shows
that the door lock will shortly be unlocked.

The door will not actually be unlocked until
the green LED by the "door unlocked"
comes on, accompanied by an audible
signal. This takes about 1 minute.

Troubleshooting

If the machine won’t start, check that:

•

the circuit breaker is on.

•

the manual shut-off valves for water are
open.

•

a program has been selected.

•

the door is properly locked.
