Spray arm monitoring/wash pressure
Problem
Possible cause and solution
Spray arm monitoring - upper
spray arm: Spray arm blocked
or excessive foaming
or
Spray arm monitoring - lower
spray arm: 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.
– Wash items are obstructing the machine or basket spray
arms.
Arrange the wash items 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.
Start the program again.
– 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.
Then reprocess the wash items again.
Spray pressure exceeds
tolerance
The wash pressure differs from the reference value.
Possible causes of fluctuations in the wash pressure
include:
- defective water connections,
- open adapters,
- foam build-up.
Identify and resolve the cause of this.
The program is not interrupted. Nevertheless, the wash
load must be reprocessed.
Spray pressure fluctuating too
much
A program was interrupted because of severe fluctuations
in the wash pressure.
Possible causes of fluctuations in the wash pressure
include:
- defective water connections,
- open adapters,
- foam build-up.
Identify and resolve the cause of this.
Reprocess the load again.
