Question by billyboy5529: need help with my pressure washing machine?
I bought a 13hp honda cold water pressure washing machine a few years ago and when I started it the other day, all seemed ok. It started only after 3 pulls, but then once I tried to use it, no water came out. Now, I know a little about pressure washers but maybe someone out there is an expert. I checked the trap which has a screen in it to stop dirt, debri etc from entering the pump. It was clean. My garden hose is not clogged with anything and yes, the water was on. My only guess is that maybe the pump is shot. I checked the pump oil and it is clean and full. I even took the wand off the pressure washing hose to make sure it isnt the wand, still no water coming out of the hose. If its the pump, is it worth taking to get fixed or maybe a new pump installed. I only payed about 800 bucks for it at Home Depot and made my money back on it in a month or so but It would kill me to toss it especially when the engine still runs like a top. Please let me know if you have any suggestions. thanks

It would seem that even if the pump was bad water would come out of the wand. Could the hose be stopped up?

bugs and spiders crawl in the inlet over the winter and make a nest which sticks pretty well and hard to clean out…. when the engine is running do you get any water on the outlet side? if not it’s plugged up good, those pumps are usually bullet proof, esp Honda’s. If anything the lil pressure oring is bad on the pump side pretty easy to fix and take apart. Are the connections correct? Sometimes hd & Lowe’s employees don’t know jack about following assembly instructions
Hi. The pump is probably not shot. If the motor does not sound like it is under any load when you are trying it the problem is that the ‘unloader’ valve is sticking. This valve when you let go of the trigger automatically senses that the pressure is building up too much and triggers the pump pistons to stop pumping. If you have an adjustable pressure knob you are looking nearly at the valve when you grab the knob. Sometimes you can break the thing loose by adjustments or you may have to take it apart. Hope this helps.
