Pressure Washer Help
Posted on 5/20/23 at 8:29 am
Posted on 5/20/23 at 8:29 am
So I went to fire up my pressure washer and had white/gray sludge erupt from the gasket between the engine and the pump.
Anyone have a sense of whether this is fixable or worth taking to a repair shop? It’s a commercial grade washer so hoping to avoid replacing it.

You've got a bad seal and the water is mixing with either the gear oil from the pump or the engine oil. If you're halfway mechanically inclined you can fix it.

The DeWalt DXP series machines I've seen have industrial-grade triplex pumps with service kits available, and are designed to be operated for decades.
Rule of thumb: if your pump has a separate oil reservoir for you to fill, you should have it serviced and not discard it.
If you've got a sealed axial cam pump with no separate oil reservoir to fill, you'd typically buy a bolt-on replacement pump rather than repair it.
ETA: search your DeWalt DXP model number online to find the cost of its pump service kits.

I’ll take a crack at it then, didn’t want to waste my time if it was a lost cause.
Thanks for the ID.

So quick follow up. Spoke to a local repair shop and he claimed the pump was toast and needed to be replaced to the tune of $400 for the part alone.
You're pretty confident I can just replace the pump seal, top up the gear oil and the pump mechanicals should be ok?

Look at it like this. If you can't fix it you're right back where you are now; having buy another one.
If you can fix it, you saved yourself several hundred duckies.

It's possible that the pump is toast, but a scumbag shop owner once told me that about equipment that needed only a cheap fix, figuring that I'd abandon the gear there.
If yours is a DXPW4035 (as I'm guessing from the blurry tag), it's got a either a 530010 or 7112736 pump. These start at $289 plus shipping.
That Honda GX270 engine should be a keeper. Mine have lasted decades.

Curious at the outcome. Were you able to fix it?
As another poster said, the Honda engine alone is worth saving. I have an old pressure washer with a 13hp Honda on it that's at least 25 years old that runs like a top still.

pressure washers are like trailer lights...I’ve given up on them. Rent when needed

Really want to thank everyone for their help with this.
Im working with Dewalt to get the pump replaced as this particular model has pages of issues with it which surprised me with a commercial grade unit that has only seen light residential use.
Ill let everyone know how it turns out. Don't want to spend money if they will warranty it, but if I end up having to come out of pocket for it ill be considering similar pumps without the pages of bad reviews.

These use a range of pumps - some Italian, some Chinese, etc.
