Spray arm monitoring / conductivity / wash pressure
Problem
Possible cause and remedy
Spray arm monitoring - upper
wash cabinet: Spray arm
blocked or excessive foaming
or
Spray arm monitoring - lower
wash cabinet: Spray arm
blocked or excessive foaming
or
Spray arm monitoring - mobile
unit spray arm 1 - : spray arm
blocked or excessive foaming
The rotation speed set has not been reached because...
- ... items are obstructing the machine or basket spray
arms.
Arrange the load so that the spray arms can turn easily
and start the program again.
- the relevant spray arm is blocked.
Clean the spray arm.
Check whether the filters in the wash cabinet are clean
and correctly inserted.
Re-start the program.
- ... wash pressure is too low due to a heavy build-up of
foam.
Follow the instructions regarding foam build-up in
"Chemical processes and technology".
Start the
Rinse
program to clean the wash cabinet.
Prepare the load again.
Conductivity level too high:
Actual value: µS/cm Max
value: µS/cm
Carry-over of conductive substances during reprocessing.
Check the process.
Empty or faulty water softener or demineralization system.
Check external water softener or demineralization
systems.
Reactivate the systems if necessary.
Work on the on-site water supply.
Contact a suitably qualified plumber.
Plumbing connections transposed.
Observe the markings on the plumbing connections (see
"Connection to the water supply").
Conductivity level exceeds
limit
Conductivity value cannot be determined because the
value is out of range (too low).
Contact the Miele Service Department.
Conductivity module requires
calibration
The conductivity meter must be recalibrated.
Contact the Miele Service Department.
Conductivity module
communication error
The connection to the conductivity module is disrupted.
Contact the Miele Service Department.
