Dispensing/Dispensing systems
Caution when handling chemical agents.
For all chemical agents, the chemical agent manufacturer's safety instructions as given
on their safety data sheets must be observed.
Problem
Cause and remedy
The dispenser for powder
cleaning agent contains
residual agent at the end
of the programme.
The dispenser was still damp when cleaning agent was
added.
Make sure the dispenser is dry before adding powder
cleaning agent.
The dispenser flap was blocked by items in the cabinet.
Rearrange the load so that the flap can open.
The dispenser flap will not
close.
Residual cleaning agent is blocking the catch.
Remove the cleaning agent.
DOS Refill
During a programme sequence a low level of liquid
chemical agent in a container has been identified.
Replace the empty container with a full one.
Programme could not be
started. Vent DOS
A programme cannot be started because ...
... there is air in the dispensing system.
... the dispensing system has been sucked completely dry.
Check the level in the supply container. Replace an
empty container with a full one, if necessary.
Vent the dispensing system.
Dispensing system DOS
venting
This is not a fault.
The dispensing system will now be automatically vented.
Wait until the venting process is finished.
Venting DOS cancelled.
Venting must be repeated
Venting of the dispensing system was cancelled 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 aperture of the siphon for blockages
and remove these as necessary.
Start the venting process again.
Contact Miele Service if there are leaks in the dispensing
hose or a fault with the siphon.
