» Clean the strainer. » Replace the O-rings of the elec- trodes. » Install new electrodes (48). Make sure that the electrodes are posi- tioned correctly (see exploded view). The deposits in the upper part of the cylinder can be conductive and lead to unwanted cur- rents between the electrode connections and the sensor electrode and thus to the mes- sage "cylinder full".
» Put the cylinder halves together and reconnect them with the flange clamps. When operating with partially softened water or tap water, scale may be discharged with the steam flow and may settle in the nozzle positioned in steam hose adapter. Therefore, this nozzle should be inspected regularly as part of the general maintenance review and cleaned if necessary.
