Pressure Washer Cutting Out

i finally got around to pressure washing the decking, but the pressure washer keeps cutting out, so only got half of it done

i can't find the instruction manual for it either, its a Kew Alto Force 5100 X-Tra pressure washer, anyone any ideas where i can get a manual for it or what the problem might be?

It will be thermal cut out on motor to stop it burning out. These are not designed for continuous use try running 10-15 mins on and 10 off to let motor cool down.

ok found this elsewhere, not sure what it means though:

I have a Kew Alto Force X-TRA that I have had for 5 years or so and has worked fine until recently.
Usually works fine initially then it stalls and will not pump. I have found that if I turn the cold water supply off and release the pressure eg disconnect the feed hose at the tap, then reconnect it, it starts working again, sometimes until next time I stop using it, sometimes for a while (sorry, not sure exactly how long).
I assume there must be some form of a pressure sensor on the cold water feed that is giving a false reading and resets when the pressure is released?




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.




Don't throw away the washer yet. I got the washer working again. Here's how. Dismantled the washer and the pressure switch which is screwed into the unit. The switch has the power leads connected to it via a little nylon box. You need a spanner to unscrew the switch. Part of the switch is made of plastic. The switch has a plastic pin on which are tread-ed two concentric pressure steel springs to hold against the water pressure. The inner spring which was rusted to pieces has a smaller diameter . Possibly this smaller springs function was to avoid pulsating pressure. Anyway the pieces were jamming the movement of the pin thereby stopping the switch from operating. I removed the loose spring fragments but left the pieces I could not remove as they hung as rings on the pin. Then I greased the spring and pin with propeller grease. Before I mounted the washer I also took out and cleaned the three pistons. After assembling the washer pulsated for a few seconds in the beginning but operates fine now and has done so for a month. May be the pressure is slightly lower, but the repair was worth the effort.


so sounds like if i take it apart i might be able to fix it? where is this pressure switch likely to be? near the water inlet filter or near the on/off switch or where? or am i likely to make a mess of it and have the whole thing explode or electrocute me?

Have same problem with force 5100 extra. There is a good video on Youtube showing how to replace the pressure switch ([ame=http://www.youtube.com/watch?v=alBc8AK8bmE]How to repair the KEW Alto Force 5000 pressure washer - YouTube[/ame]) but the early part showing case removal is where I'm getting trouble! Have removed the two cross head screws holding the handle and also two torx T20 (shallow recessed) screws on the base but cover is still secure. Can anyone help?
