ALTO FORCE KEW COLD WATER POWER PRESSURE MACHINE STOPPED

if water is available and no pressure yhen the pump has failed. look online fort parts breakdown for you particular model.

Hi really hope someone can help as I couldn't find a manual for my kew alto 1640hot and cold diesel pressure washer, problem is when I turn it on from been stood over night !i press on button and I see a f then a 1 flashing on the display ,anyone know what it means or we're the fault is,

LF Error code: LF stands for long fill and occurs when the water level does not change for a period of time after the valves are turned on.

All washers are designed to operate with a water supply pressure of 20-100 PSI. When the pressure drops below 20 PSI the washer can have the following problems:

* Slow Fill- low water pressure reduces the speed at which water flows into the machine.
o Verify the pressure at all other water sources in the house (i.e. sinks, showers, etc..). If you find other places where the pressure is low, the problem is not with the machine but with the water supply.
* Continuous Fill- The valve may not fully seat under 20 PSI which would allow for a constant flow even when the machine is not supposed to be filling.
o Contact the water company to verify the pressure being supplied to the house.
* dispenser- Needs a minimum amount of pressure to function. May dispense constantly, at the wrong time, or not at all.
o A plumber may need to be consulted if the pressure is found to be too low.

Things you can check :

* Are the Hot and Cold water faucets turned on
* Are the water hoses kinked
o Make sure all the hose are straight and able to flow water
* Are the screen inside the water valve plugged
o Inlet valve should be free of debris and rust.
o Turn off water and remove the inlet hoses from washer.
o Remove any accumulated film or particles.
o Assure rubber washers are in the end of each inlet hose.
o Reinstall hoses, turn on water and check for leaks.

Error codes can be caused by a Power Surge or other electrical anomaly,attempt to return the washer to operation by following the Hard Reset procedure below.

1. Unplug or turn the circuit breaker off for 30 seconds.
2. Reconnect the unit to the power source by turning the breaker back on or plugging the unit back into the wall outlet.
3. Press the Pause/Cancel/Stop button twice to clear the display.
4. Start a short cycle to check the operation of the machine by selecting a cycle and pressing and holding the start button until the machine starts

Try the machine without the high pressure hose on. if that fails you will need to check that you have power to the switch on the machine.

Have the same p-washer (5-6 years old) and the same problem. Opened it and the pressure switch is the crook. A plastic pin has an inner and an outer spring on it (two consentric springs). The smaller inner spring is completely rusted away so the switch no longer operates correctly. Obviously the spring was of a too low quality. The service office say a new switch cost around 400NOK (50 euros) - so the washer is too expensive to mend. But I will try to get it working without the inner spring. Doubt if I succed. So will have to dump the washer.

Hi, You can get this seal set for a 1502v from nilfisk alto or any alto dealer.

force feed the pump and check for any leaks on water filter or behind pump head

Hi Steve, In 3 years of repairing pressure washers I've only ever seen one of these, and am having a hard time remembering much about it, except that it was really awkward to work on! Strictly speaking, many small pressure washer repairs are uneconomical, because the labour time involved costs almost as much as the machine is worth. However, a "motor won't go" problem does narrow things down a lot. To state the obvious, we're looking at an electrical problem. The challenge is to find the cause! Did the motor stop while you were using it, or did it fail to start when you got it out of storage? If you are in the UK you should first check the plug-top fuse and the full length of the flex for any damage. If you have any kind of low-voltage electrical testing device, you can test for continuity between the live and neutral pins of the plug (with the machine switched on you should have continuity). If you have no continuity (and the fuse is OK) there may be a problem with the switch on the machine. Unfortunately, unless you are a really keen DIY person, there's not much you can do by way of self-help. A repair centre may be able to help you, but beware of costs spiraling beyond the cost of a replacement machine. I hope this will be helpful - if you can give more details I'll help further if I can. Good luck!

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

To remove the cover, undo the two screws holding on the equipment tray on the handle. Then turn upside down and undo the two screws on the bottom. You will need a very long handled screw driver to reach into the deep recesses. I think they may to TORX screws (working from memory and has been a while since I pulled one apart). The blue cover will now pull off. The only trouble you may have is that the bolts are ordinary black steel ones and may have rusted through

Most likely fault is that the pressure switch has failed open. A combination of dirty water leaking past the seals and rust will eventuall jam the switch. The switch assembly is the white plastic part directly bolted onto the pump. A plunger is pushed by the pump when it is up to pressure which trips a micro switch and turns the power off. You will need to replace the complete pressure switch which is about $60. If you take care the micro switch assembly can be removed and then put back onto the new switch. If you break it, then another $40.
