8 Troubleshooting

Fault Cause Remedy

Pressure drop > Air in the system • Vent the system by

operating the spray gun

several times at short

intervals. If necessary,

operate the cleaner for a

short time without the high-

pressure hose connected.

> High pressure nozzle blocked

worn

• Clean/replace the high

pressure nozzle

> Detergent tank empty • Top up detergent tank or

set detergent metering to

“0”

Pressure ﬂ uctuations > Pump draws in air (only

possible in suction mode)

• Check that the suction set

is air-tight

> Lack of water • Open water tap

> Water inlet hose is too long

or its cross-section too small

• Use speciﬁ ed water inlet

hose

> Lack of water caused by

blocked water ﬁ lter

• Clean the water ﬁ lter in the

water connection (never

work without water ﬁ lter)

> Lack of water because max.

permissible suction height

has not been heeded

• See instructions

The motor does not start when

the cleaner is switched on

> The plug is not inserted

properly, i.e. there is no

current

• Check the plug, lead and

switch and if necessary

have them replaced by a

trained electrician

> The mains fuse is switched

off

• Switch on the mains fuse

When the cleaner is switched

on the motor buzzes without

starting

> The mains voltage is too low

or there is a phase failure.

• Have the electrical

connection checked

> The pump is blocked or

frozen

• Contact the Nilﬁ sk-Alto

customer service

> Incorrect cross-section or

length of the extension lead

• Use lead with correct cross

section or length

The motor switches off > The overload protection

has been activated due to

overheating or overloading of

the motor

• Check that the mains

voltage and the cleaner

voltage are the same.

Switch off the cleaner and

allow it to cool for at least 3

minutes
