• Occasionally check the amount of water coming from the flow meter. If
the amount is not correct, recalibrate in accordance with the procedures
set out in Chapter 16.
• The impeller in the flow meter is sensitive to contaminants in the water
and after long inoperative periods, the impeller may stop functioning.
• If the impeller is not working properly, or if the connection between im-
peller or control unit is broken, the water intake will stop at 8 litre.
• In this case, check the electrical connection between the impeller and
control unit or or ascertain where the impeller may be stuck open and
clean the impeller in accordance with the following instructions:
o Remove the electrical housing (Unscrew the side mounted screw and
twist and lift off the housing.)
o Unscrew the 4 screws on the impeller housing and remove the impel-
ler plate with impeller.
o Carefully turn the impeller and rotate (blow on) the impeller until it
rotates free.
