How To Diagnose and Replace a Pressure Washer Water Pump

Good video. I have the same pump on my Craftsman PW that was purchased in 2008. It has been barely used 5 hours and still running strong. I went to the pump manufacturer website and downloaded the owners manual for the new pump.

All those hex sockets for you to use EXACTLY what the engineers had in mind! lol

Nice replace instructions, very thorough as always. I used a power washer a few times in the past and I thought it was fun. Thanks for another useful video! 🤗👍🏼

I wanted to say that You did a good video on this and it worked for me, it took patience and when I tried to start - I almost gave up - but the engine started and the power washer was pumping !!! thanks for your explanations 😶

Got that pressure washer running good now so you can clean that deck that you worked so hard on. You are a hard working man.

Very nice video. I m working on one very similar. I was dreading taking the pump off, but you show exactly what I will find. Thank you.

Some just love the sound of their own voice...

Very informative video thank you

Hello. I have an HDS 8/17-4M machine that is having an error when switching to eco mode but cannot heat water. There is no error message on the screen. I hope to receive help from you and everyone. Thank you.

I have been picking up used pressure washers listed with description runs but not building pressure. Not leaking..... been usually finding them with Honda motors very similar to yours for no more than 50$(once I paid 75). I am only sharing this because I think you missed the number 1 reason for you symptoms, "A malfunctioning😮 check Valve. Every time I have purchased a unit with a pump that had little to no pressure building, it was always the check valve. Such an easy fix. The best part is not once did I need to buy a new valve, only remove and lubricate it and reinstall,!! That's it!!.., ( 3 pumps saved0 on gas and twice on an electric unit,,) that's 5 fixed, zero failure and zero ,$spent !! The only times it was a ruined pump the pump was cracked and leaking . ( I avoid them if the pump is leaking or cracked, because of the cost to buy a new pump) hope this is useful for the future content.. Patrink14615

Did you have any problems removing the hose from the old pump? I don't have water pump pliers but my slip joint pliers usually get the job done. Have I missed any special technique required to remove the hose?

Can you not upgrade a pump? I have to get a replacement pump for a magnum 4000 series gold I just got for cheap. I looked it up and it looks like the pump is a 3.5gpm. But there’s so many pumps that look just like it? Could I get a 4 or even 5.5gpm pump to replace it with and have an even better pressure washer? What’s the limitations on that? Why wouldn’t it be able to be done? Help I’m a complete beginner lmao
