What to do if my Nilfisk-Advance MH 4M motor overheated?
If the Nilfisk-Advance Floor Machine is overheating, turn the main switch to the OFF position and let the machine cool down. Also, remove or disconnect any extension cables. If the issue persists, it could be a phase failure, and you should contact Nilfisk Service to have the electrical connection checked.
Why is my Nilfisk-Advance MH 4M Floor Machine leaking?
If your Nilfisk-Advance Floor Machine is experiencing leakage, several issues could be the cause. Check the spray gun for leaks. If the high-pressure hose, coupling, or line system is leaking, replace the high-pressure hose and retighten the screw fittings. If the detergent tank is empty, top it up or set the detergent metering to “OFF“. If the water inlet filter is dirty, clean it. If the high-pressure pump is drawing in air, repair any leaks.
Why Nilfisk-Advance Floor Machine running with pulsating pressure?
If the Nilfisk-Advance Floor Machine is running with pulsating pressure and making a knocking noise, it might be because the pump has drawn in air due to an empty detergent tank. To resolve this, close the detergent valve, remove the lance from the gun, operate the spray gun, and let the machine run until the air in the pump is gone and the machine runs normally again.
How to fix low pressure on Nilfisk-Advance Floor Machine?
If the Nilfisk-Advance Floor Machine has low pressure, the high-pressure nozzle might be worn out and needs replacement. Alternatively, the pressure regulation might be set too low, or the VarioPress-lance is set to low water volume. Turn the twist grip on the safety control block clockwise (+) or set the Vario-Press-lance to a higher water volume.
Why Nilfisk-Advance Floor Machine not drawing detergents?
If no detergents are being drawn into your Nilfisk-Advance Floor Machine, first check if the detergent tank is empty and top it up if needed. If the tank is full, there might be dirt in the detergent tank, so clean it out. Also, the suction valve at the cleaning agent inlet could be soiled; remove the suction valve and clean or replace it.
