Re: Alto Force Kew washer stopped working.
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.
I pulled mine apart before I read this (it would have saved a heap of trouble if I had read this frst, as it took ages to find the two screws underneath, which are torx). Like others I found that the pressure switch was jammed up with rust. I cleaned it up and got it moving, but managed to break off the two tiny lugs at the top of the switch, so it will now cut out, but not cut back in. Trying to source spare parts in Australia, but only found one company here (have sent an email to see if they have any) and one in England, who seem to have them.

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,
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 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!
The answer of "Firehead" is correct. You have a start/stop valve with springs (springs = maybe broken by the rust). Kew sells a kit to repair. If you want i'll send a diagram to you.
