Easy fix for non-working Pumps
By JL5043 on Reviewed in the United States on September 10, 2017
If your pressure washer completely stopped working, read this! I had bought this pressure washer just over 2 years ago for one job lasting about 4 hours total. At the time, I put the unit away and forgot about it for 2 years until I needed it this summer. When I took it out and fired it up, the pump ran for about 5 seconds then "died." I tried for days to get it to work with no luck. I was one week over the 2 year warranty, so I was pretty ticked off I was stuck with this hunk of junk. Then talking with a guy at work he mentioned you're supposed to use a pump protector lubricant after each time you use the pressure washer. I read up on this a bit, and the leftover water in the unit can cause the pumps internal gaskets to seize up. This might be due to the minerals in the water, I don't really know. I was considering buying a different unit, then thought I'd take a shot at using the pump protector liquid on my "dead" pressure washer. At Wall Mart I bought "Powerfit 3oz Power Washer Pump Protector" in the tools isle. This $5 liquid brought my pump and pressure washer right back to life!! You actually screw the plastic threads on the bottle into the threaded garden hose inlet on the pressure washer. Then just squeeze the bottle a bit. I didn't realize if I was doing it right because I couldn't tell if the liquid was actually going in. About 10 minutes later I connected the hose and the unit worked. Hope this helps some people! Update 5-21-18 - Another easy fix for dead unit :) ------------------------------------------------------------------------ This week I had an issue with the pump not starting, that the power wash pump protector liquid trick didn't fix. I tried different outlets thinking it was an electrical issue. It turned out to be an electrical issue within the GFCI plug of the power washer unit (likely from me leaving it outside in the rain a few days last year.) With the unit unplugged, take a phillips screwdriver and take the cover off of the unit's GFCI plug. With the cover popped off, if you see lots of moisture that's been trapped in the plug, that will prevent it from running. I bought a replacement plug at my local hardware store. You can find the same replacement plug I used successfully to fix my pressure washer by typing this into the Amazon search bar: "Leviton 16693 15-Amp, 120-Volt, Grounded, Compact Automatic Reset Right Angle GFCI" It's about a 5 minute job.. Just reconnect the wires to the new GFCI plug (Black wire to gold connector, white to silver) and turn the screws to secure the wires in place. Screw down the "U" shaped stress clamps that come with the new plug, they hold the wire in tightly. Then attach the new cover, and you're good to go. Update 7-20-20 - Maintenance on quick connect spray nozzles ------------------------------------------------------------------------ 5 years later my Sun Joe washer is still going strong. After your pressure washer has been around a few seasons, it's possible that the very fine holes in the quick connect spray nozzles will get some corrosion. Any little corrosion can affect the amount of water that can pass through, and I found will often prevent the pump from running and shut the pump off. If your pump turns on and runs with no spray nozzle attached to the wand, but does not work with the nozzle attached that's a clear sign you need to do some maintenance on your nozzles to reopen the holes in the nozzle. What I did was take a bowl and fill it with Vinegar. I just used vinegar because I had it in the house, there may be other good methods to get rid of the corrosion. I soaked all the nozzles in the bowl for about 3 hours. Then I took a sewing needle and poked around the hole to clear out any corrosion. Soaked them for a couple more hours, and then rinsed them off under some hot water. Then I dried them off and sprayed each nozzle with little olive oil cooking spray to help prevent any more corrosion before storing them. There are lots of corrosion inhibitors on the market I just used something I had around. This method worked well as it opened 3 plugged nozzles for me.

Changed review from 5 to 3......For an electric unit, it works well.

Ok, this is my 3rd post for this review. I've never done an 'edit' review, much less 2 edits. But, I did more pressure washing with the machine cleaning an aluminum pool cage, and had another issue. The plug got wet, and worked as it's supposed to.......it tripped and killed the power. No biggee, reset the button on the plug and continue. That didn't work, it kept tripping and would not reset. So, I figured I'd take the plug apart and dry it out. It should've not gotten wet internally, but I figured it must have. First problem with the plug was taking it apart. They used a 'non standard' screw to hold the plug together. 5 of the 6 screws were phillips head, one had a head with just 2 holes in it (see picture) requiring a special screwdriver -- which I do not have. I used small needle nosed pliers and worked the screw out. Supposedly others manufacturers use a similar screw in electrical applications, but it is unnecessary and annoying. Might be code in some applications. Second issue with the plug is the 'waterproof' white reset buttons on the plug do not seal........so they are not 'waterproof'. (See picture). They easily come loose inside the plug. Third issue was the gap beside the metal plugs that go in the outlet (see picture). It appears that water can get in those holes, they are large. The plug actually had a nice rubber gasket that should've sealed the plug well, but obviously the plug has areas that allow water in as I found water in the plug when I took it apart. This plug does not fare well in wet environments. A poor plug to use for a pressure washer that will have water around it all the time. I considered downgrading to 2 stars on this edit, but did not. Machine works, it's just not a stellar product. The Greenworks machine my son had worked well until the pump gave out. Probably should've just replaced the pump on it. It was reliable and solid. --------------------2nd review------------- I have changed my initial 5 to a 3 star for one simple reason..........Sun Joe has made their hose connections non-standard. They MISLEAD you by saying the hose connector is M22, which is standard, but the inside diameter (ID) is not. The Sun Joe hoses are NOT compatible with other electric pressure washers. I had planned to use my other extra hoses to extend my reach. I bought a coupler from Amazon to connect my extra hose to the Sun Joe hose. The couple fits my extra hose, but not the Sun Joe hose. And, my extra hose will NOT fit the Sun Joe washer. I am quite disappointed that Sun Joe has gone to proprietary hoses and connections. I would NOT have bought it had I known this. -----original review------ I've used gas powered, 3000+ psi washers for years but got tired of the weight and gas and noise, so tried this one. My son has this unit also, and likes it. It's lightweight, fairly quiet (don't need earplugs to use), and for a 2000 psi machine, it cleans decently. If you expect it to blast like a high powered gas unit you will be disappointed, but for most home cleaning jobs it does very well apparently. I just got it, so my experience so far is cleaning my gutters, the facia and soffit, and walls of my house. I've cleaned some mold off concrete and other areas, and it does fine for that. I used the 15 degree nozzle for all my cleaning so far, and you do have to get fairly close (6-8") for most cleaning, and closer (4-5") for concrete cleaning. I wish the hose was longer. The 20' hose isn't long enough if you're on a ladder reaching high places, you have to move the washer often. And, I have some very high areas on my house that the hose won't even reach, so I'll have to elevate the unit to get to them. Needs a 30' hose minimum. This Sun Joe hose is heavy duty. My son had a Greenworks washer and the hose on it was flimsy, kinked easily, and developed a hole from a kink. Hopefully it is durable and will last. It is suprisingly light weight, which is nice for transport and moving. The hose connections are solid and appear durable. Hopefully the motor and other componenets are durable and will last. Time will tell.
