No flow was detected when dispensing from an external
container.
Take care when using process chemicals.
For all process chemicals, the manufacturer’s safety in-
structions as given on their safety data sheets must be
observed.
Check the level in the containers and replace empty
ones with filled ones.
Check the suction apertures of the siphons and remove
any deposits.
Check the hose connections on the siphons, the washer-
disinfector and any dispensing modules.
Remove any kinks from the dispensing hoses and check
the hoses for leaks. Position the dispensing hoses so
that they cannot kink.
Vent the dispensing systems.
If you identify any leaks in the dispensing hoses or defects
on the siphons, contact the W&H Customer Service De-
partment.
