Cleaning the water inlet filters
These round wire gauze filters placed on either end of the water hose to mains, often become
blocked in the first few days of use, especially when the plumbing installation is new. Clean
them under a jet of water.

Cleaning for water leaks
This must be done whenever maintenance is carried out on the machine: check all water
connections, braces, tubes and hoses in order to eliminate leaks and prevent breakages and
flooding. Check that the valve closes tightly on models with an automatic cleaning system.
NOTE: You will observe that after a certain period of functioning (the running-in period), low-
pressure pressostats may need to be adjusted. This second adjustment will be final.
