Pressure washer intermittent turn on

Alto 5100 old model washer. Started using it after long time of disuse. Motor doesn't start most times, until I disconnect and reconnect input hose. It's a long springy (soft) hose. Once started, it's ok until I stop washing - then pulling trigger doesn't start it

Sounds like a pressure switch is sticking. usually causes this problem especially after being stood for a while not used.

have to remove cover to get to pressure switch, remove pressure switch piston clean regrease with silicon grease refit it m and all should be good.

Portercable Pressure Washer Model PCH2401


when the trigger for the wand is not pulled , there is a pressure relief valve that bypasses the water in the pump and so there is no pressure until the trigger is pulled again.
with the pump getting hot and not being able to pull the motor to restart, it indicates that that pressure relief valve has jammed ( faulty ) and the pump is running at full pressure all the time
That will heat the pump and stop the engine from restarting
That valve is where I would start looking for a problem

This sounds like it had water left in it and it froze over the winter. The motot turning on and off signals a water leak on the output side of the pump. You may have a cracked pump housing. Locate the pump and make sure nothing is leaking in that area when under pressure. looh for fine hairline cracks.

Kew Alto Force X-TRA cold water supply pressure sensor problem


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.

Alto Kew pressure washer stopped working!


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!

Honda gas power pressure washer runs for awhile then cuts off.


did you pour all of the old gas out before you started to use it. Sometimes condensation builds up in gas tank when stored. You need to dump old gas an put in new gas.

ALTO FORCE KEW COLD WATER POWER PRESSURE MACHINE STOPPED


Hi FRANK,
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.

Honda GCV160 5.5 on a pressure washer runs only intermittently


The problem is the plastic float in the carburetor, it's not adjustable and after sitting up with gas in it it distorts. Save yourself the trouble and buy a new one, you can get them online for $15-$20.

I squeeze the trigger, I have pressure for 2-3 seconds and the engine dies.


your pump is probably cavatating. when you first hook it up and turn hose on open thr trigger and let water run thru until it quits spitting and flows smooth. then crank it up and see if this gets it done. if not you could have a problem with the pressure valve bolted on the outside of pump. there should be a nut shaped stem to adjust pressure . turn it in and see what happens.
