Pressure washer problem...
Posted on 5/12/15 at 10:22 am

My Husky pressure washer won't build any pressure. 2200 PSI and 2 gal/minute specifications. B & S engine runs great, but the pump just won't build any pressure. Pump doesn't look that difficult to remove and replace, but can I just fix the pump? What could be the problem? TIA

I know the good Cat pumps can be torn down and fixed. What kinda pump is on it?

Not sure what kind of pump is on it. It's on the bottom of the unit and I haven't been able to locate a brand name on the pump. It's the original pump and it worked fine last summer. Right now, though, it's just putting out the same pressure that's going in it. This is what I've got: LINK

May be best to call the dealer.

Sounds like the wheel/paddle/sprocket thing on the pump is froze up. Could be as simple as taking it apart, cleaning up a little rust with some steel wool, and reassembly.

The same thing just happened to my Simpson MSV3024 2.4 GPM 3000 PSI Pressure Washer w/Honda Engine. The engine runs fine but it won't build up pressure. I was debating buying another pump and swapping it out or seeing if i could get it repaired.

Cheap axial cam pump probably, if you didn't flush it out after use then your seals are done for. Might be able to buy a new pump.

If the seals were bad wouldn't it start leaking or dripping out of the pump?

I've never used any detergent or cleaning agents in it, so form that standpoint I've never flushed it out. Just removed the hoses and let it drain. Right now it's only putting out pressure because of the restricted nozzle. Kind of like holding your thumb over a water hose.

Could be unloader valve. Could be clogged filter. Could be rusted up tip.
What color pump is it?
Does it spray hard for a second and then very weak?

I tried adjusting the spring valve both directions and it didn't affect the output pressure at all. Clogged filter? Now I have to find the filter and check it! The pump housing itself is just plain old aluminum, not painted. Pressure stays the same. Doesn't vary a bit. It ain't hardly got enough pressure to blow a nose bougar off the end of your finger.

Inlet filter where you screw the hose in.
Could be an AR pump (some Italian name), but need model # or pics to tell. If it's just a junk pump, sell it and buy a new pressure washer
Forgot to ask...Is the pump on bottom, or bolted to the side of the engine? If it's on bottom, throw it away and get a new pressure washer
Did you change tips?

Pump is on the bottom. Changed tips and no difference. I'll check the filter now. Gotta ask, though, why throw away the whole pressure washer because the pump is on the bottom? Pressure washers ain't exactly cheap! My sociable security check only goes so far...

They are cheap pumps. You can't get parts, find someone to work on them, and can't buy a new one. You also can't adapt a good pump to work on them. You get what you pay for in the pressure washer world.
Maybe you could sell it on CL

Had this happen a couple of weeks ago. I just went and bought a new presser washer.

Are you on city water or well water? If well water, there's a good possibility the cylinder walls are scored or the packings are damaged due to ball bearing sand, which is in all unfiltered well water.
I doubt your washer came with a Cat pump. You would have paid ^$ for one of those. Cat is the best in the business followed by General.
You will most likely have to replace the pump.

If his engine has been maintained, he could probably sell it to recoup the tax he will pay for the new PW.
As Hammer said, these type washers are known as throw aways.
The ideal PW will come with a good GX Honda or Briggs engine coupled to a Cat or General pump through a drive belt. They are expensive, if maintained will last for many many years.
Here's a good link for quality PWs, with a few throw aways mixed in. LINK The ones with the aqua blue pumps on them are Cat pumps.
Does it make good $ sense to spend that much on a commercial pump, that you will use three or four times a year? IDK. I do know if you do, it will most likey be the last PW you will have to buy. Ever.

I have used CAT, General, and AR pumps. They all work really well and are reliable and rebuildable

Flushing it out means removing the water by pulling the starter to force out residual water then adding in some conditioning fluid and cycling the pump which protects parts from corrosion, hard water deposits, and maintains seals. Stuff like Pump Armor. Can't let water sit in these pumps.

That's really the key, plus availability of parts.
I've used Cat and General, don't know much about AR, although I have seen some on nice rigs. everything I've owned was component built by me. I would own nothing that wasn't capable of pumping at least four gpm. It's really the volume that gives cleaning power.
