Water intake filter A on the cock must be cleaned from time to time; this should be done 1 every 2 – 6
months, depending on the quantity of water used. Close the water supply cock, unscrew the end of the water
intake hose, remove filter A and clean it carefully under running water. Reassemble filter A and carefully screw
the water intake hose back into position.
Take care not to spill water from the free end of the hose.

Cleaning the spray arms
The spray arms are easily removed by undoing the knurled nut securing them to the rotary shaft, so that the
nozzles can be cleaned to prevent blockages.
Wash the spray arms and nozzles under clean running water and carefully reinstall them, checking that their
rotation is in no way impeded.
Recommended spray arm cleaning interval: once a week.

Cleaning the filter unit
The filter unit is composed of a filter which collects large sized particles, a conical microfilter and a larger
external filter. To ensure that the appliance operates effectively, it is extremely important to keep the filters
clean. Inspect them frequently (for instance, if washing glassware with paper labels, inspect them after each
cycle – in normal conditions, they should be cleaned once a week) and remove any deposits which may
compromise their operation.
