Removing the housing from the cleaning head.

1 Toothed belt, from suction turbine
2 coupling
3 Toothed belt to the brush roller drive
4 Right vacuum bar support
5 Suction channel
6 Left vacuum bar support
7 Shaped hose, water distribution bar connection
8 Water pump (M2)
9 Water hose to the water pump
10 Suction turbine housing
11 Connector, connecting cable to water pump

1 Shaped hose, water distribution bar connection
2 Water pump (M2)

Î

Remove the cleaning head housing (see chapter 
"Removing the cleaning head housing").

Î

Pull the shaped hose off the connection of the wa-
ter distribution bar.

Î

Pull the water pump out of the water pump holder 
toward the top.

1 Shaped hose, water distribution bar connection
2 Water pump (M2)
3 Water hose to the water pump
4 Pump holder, rubber
5 Pump holder, rubber
6 Connector, connecting cable to water pump
7 Diode, soldered into the cable

The rectifier diode converts AC voltage to pulsating 
direct voltage. This will result in the water pump feed-
ing the water evenly.

The supply voltage can be read at the Molex plug.
Target value:
Water pump switch turned off = 0 V AC
Water pump switch turned on = current voltage
