THE MACHINE DOES NOT START.
No water pressure.
Make sure water is coming from the
supply hose.

when the machine is started with the
water pump connected, provide a 200
litre container from which the pump
must draw.

Insufficient power supply (blue light off).
Make sure the electric cable has the

not
insist with repeated start-up
attempts: this may damage the electrical
equipment.
