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 solution
Refill DOS
During a program sequence, a low level of liquid chemical
agent 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 completely emptied.
Check the level in the reservoir and refill or replace it with
a full container as necessary.
Vent the dispensing system.
Dispensing system DOS prim-
ing
This is not a fault.
The dispensing system is automatically being vented.
Wait until the venting process is finished.
Priming DOS canceled. Prim-
ing 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 suction wand blocked.
Check the dispensing hose for kinks and leaks. Position
it so that it cannot become kinked.
Check the suction opening of the suction wand 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 wand.
Check container/lance DOS
Little or no flow has been identified.
Check the level in the supply container. Replace an
empty container with a full one, if necessary.
Check the suction opening of the siphon for deposits.
Prime the dispensing system.
The dispensing hose is kinked.
Remove any kinks from the dispensing hose. Position it
so that it cannot become kinked.
Check the dispensing hose for leaks.
Prime the dispensing system.
Contact Miele Service if there are leaks in the dispensing
hose or a fault with the siphon.
Highly viscous (thick) process chemicals can affect the dispenser monitoring and lead to
inaccurate data. In this instance, please contact Miele Service for advice.
