Pressure washer question - water spewing out the back, low pressure?
I borrowed someones pressure washer. One day it seemed to work fine. A few days later when I fired it up again, going through all the normal steps of bleeding the air out of the lines before starting, it seemed to spit a lot of water out of the back from near the pressure manifold. So then I shut it off, disconnected everything, and re-connected just the garden hose to the inlet. Even that causes water to come from the back of the washer. Could a gasket be out?
What kind of pressure washer is it? There are different type. Is it a direct drive unit with no belts between the engine and pump?
A little more info will help in diagnostics.
Before you freak out, take a look and be sure the washer on the garden hose fitting didn't escape the last time you removed the water supply hose.
Another common problem is the o-rings inside the quick connect fittings getting lost. This would make it spray in every direction but where you aim. If you had the high pressure hose hooked up it could be leaking from there.
If it's a cheap unit with a pump mounted UNDER a lawnmower style engine.................return it to the owner and tell them it worked wonderfully and you may buy one in the future it was such a pleasure to use. Go immediately back to your vehicle and get out of there fast. Do not look back. Do change your telephone number. Do not buy one like it.

I think maybe the pump is toast. The water is coming from the motor or pressure manifold itself, not where the garden hose connects.
The honda motor cranks up fine, but it just wont put out any pressure now and the water streaming out of the back (even without the motor on) makes me think something is wonky!
Here is where i would start it it were mine.
Pull on the engine starting cord a few times to rotate the pump..Also Tap on the pump lightly in various places..It could be temp. stuck in bypass.
Let us know.
kind of describes the problem Im having
in short - possible unloader failure
Pressure relief reliving water Unloader failure / coil overheating / Excessive pressure Turn machine off wait a few minutes and restart. If problem continues take to an authorized repair center for complete system check.
I tried it again a few min ago. Same problem. Just hooking up the supply water, it spews water out of the pump area, not even wanting to go through the hose to the handle, but just a little.
Generally speaking.........if the water is making it to the motor/engine side of the pump the seals are shot and/or the pistons ( if it has some ) could be cracked allowing water to push past them.
It may be possible to rebuild the pump. A fast search of the part number you stated shows two possible pump options on that model. The simple rebuild kits are close to $100 and that's not a total rebuild for the pumps.
My opinion? toss it if the pump on it is shot. I would sell the engine on ebay and cut your losses.
A big problem with pressure washers is either not using them often enough and stuff deteriorating inside or folks leaving water in the pumps and storing the units in freezing temps that causes havok to the internals. If you take the pump aparts you may find broken/worn parts but realize it's going to cost a bit to repair.
Never lend or borrow a cheap pressure washer.
You may have cracked the pump housing. Mine let go in a spectacular fashion and was not worth fixing.
That looks like a $300 unit, the Cat pump I have on my current PW costs over $300.
I bought a stupid-a$$ foreign yellow electric one. Used it maybe 4 times and it's toast. Looked online, and it seems it's pretty common to get 3-4 uses for your $200+ before they have to go back to the factory for expensive repairs that last another 3-4 uses.
Next time, I'm renting one. Wouldn't dare borrow one!!!
