With the head in the washing position, press the accelerator pedal N lightly and briefly to start brush rotation,
operate the solenoid valve F and detergent pump.

Read the voltage on the digital multimeter.
20a
If the voltage read is between 36 V and 30 V and when the cap connector H is reconnected to the solenoid
valve F, this does not command raising of the membrane to open the port, replace the solenoid valve F with
a new one.
20b
If the voltage read is below 30 V or absent altogether and the batteries are charged, check the electrical
wiring powering the solenoid valve and/or the output from the circuit board, see paragraph B3.2.
20c
If the circuit board and solenoid valve function correctly and the wiring is in good condition, check that the
filters and water delivery hoses are clean.
