How to fix low pressure on my Nilfisk-ALTO NEPTUNE PE?
If the pressure is too low on your Nilfisk-ALTO Pressure Washer, the high-pressure nozzle may be worn out, or the pressure regulation might be set to a low water volume. Try replacing the nozzle or turn the twist grip on the spray lance to a higher water volume.
What to do if green and red LEDs flash simultaneously on my Nilfisk-ALTO Pressure Washer?
If the green and red LEDs flash simultaneously on your Nilfisk-ALTO Pressure Washer, it indicates a leakage or an inadmissible operating condition due to short-time operation. This can be caused by a leaking spray handle, high-pressure hose, coupling, line system, dirty water inlet filter, or the high-pressure pump drawing in air. Check the spray handle, replace the high-pressure hose, retighten screw fittings, and clean the filter. After three times of short-time operation, the heating switches off. To reset, turn the main switch to the 'OFF' position, then start again. Keep the spray gun pressed for longer than 3 seconds. If a leak occurs causing the machine to start and stop briefly 3 times, then the heating will switch off. Cold water operation is possible.
