Maintenance should only be performed by qualified personnel
Always check the indicator lights on the machine before calling maintenance staff, as simple remedies may
work.
Problem Possible causes / resolution
Machine is not clean internally
after use

the main water solenoid valve is operating.
Make sure that the main isolating valve is open. Is the water isolator
service valve in
the ‘Open’ position?
