Dispensing/dispensing systems
Caution when handling process chemicals.
For all process chemicals, the process chemical manufacturer's safety instructions as
given on their safety data sheets must be observed.
Problem
Possible cause and remedy
The dispenser for powder
cleaning detergent
contains residual agent at
the end of the program.
The dispenser was still damp when cleaning detergent was
added.
Make sure the dispenser is dry before adding powder
cleaning detergent.
The dispenser flap was blocked by items in the cabinet.
Rearrange the load so that the flap can open.
The dispenser flap for
powder detergent will not
close.
Detergent residue is blocking the latch.
Remove the detergent residue.
Refill DOS
During a program sequence a low level of liquid process
chemical in a container has been identified.
Replace the empty container with a full one.
Prog. start not possible.
Prime dispenser pump DOS
A program cannot be started because ...
... there is air in the dispensing system.
... the dispensing system has been sucked completely dry.
Check the fill level in the supply container. Replace the
empty container with a full one if needed.
Vent the dispensing system.
Dispensing system DOS
priming
This is not a fault.
The dispensing system will now be automatically vented.
Wait until the venting process is finished.
Priming DOS canceled.
Priming must be repeated
Priming of the dispensing system was canceled because an
insufficient flow rate was identified. A dispensing hose may
be kinked or the siphon blocked.
Check the dispensing hose for kinks and leaks. Position
it so that it cannot become kinked.
Check the suction opening of the siphon for blockages
and remove them as necessary.
Start the priming process again.
Contact Miele Service if there are leaks in the dispensing
hose or a fault with the suction lance.
