Pressure Washer: Power washer blows the line off the soap reservoir.

Sun, 09 Jun 2024 05:44:34 -0700

Honda GCV 160 Black Max BM80913 Power Washer wasn’t drawing soap… I took off the line to check for blockage, none found so reattached the line. Now, when I turn on the water and start the engine, water is forced back through the soap line & blows the cap off the reservoir, then the line off the pump fitting, and what doesn’t make it through the hose & wand continues to spew all over from the fitting.

Anyone have some insight as to what has caused this to occur?? I’m thinking disassembling the pump is not recommended given my lack of knowledge regarding these units. Any guidance will be very much appreciated!

Pressure Washer: karcher pressure washer cycling

Sat, 30 Jun 2018 08:21:31 -0700

My pressure washer keeps cycling on and off while the trigger is pulled.

When trigger is released, the washer shuts off as normal, but when the trigger is pulled, the unit cycles on and off. Does anyone know what might cause this?

Pressure Washer: Karcher power washer don't work

Wed, 13 Sep 2017 11:34:41 -0700

Power washer has no high pressure water come out of it. I've watched all the videos I can find on YouTube and I still haven't figured out what's wrong with it. I've looked at the valves. In fact I have 2 of these power washers that don't work that I have had a part and looked at the valves and I'm not seeing anything wrong with any of them. Do you have any idea what might be wrong with these two power washers are there any other video other than YouTube that you can recommend.

Pressure Washer: Brand new pressurer washer no pressure.

I bought a pressure washer 4 months ago when they went on sale at Sam's Club. It's a Troy Bilt 3400 psi 2.3 GPM gas model, model number TB3400PWXP. I finally went to use it for the first time today and it is not making pressure. It fired right up, I made sure the pump was primed first, then started it, and it makes no pressure. The stream of water coming out of the nozzle is the same if the engine is running or not. What is the most likely cause?

Pressure Washer: Best way to handle stubborn outdoor grime with a pressure washer?

Fri, 22 Aug 2025 01:04:22 -0700

Hey everyone,

I’ve been working on cleaning driveways, decks, and patios with my pressure washer but I’m not getting the best results.

Here’s what I’ve tried so far:

Standard pressure-washing (2000–3000 PSI) with detergents
Letting surfaces air-dry overnight
Multiple passes with different nozzle angles

Still, some stains refuse to come off.

So I’d like to ask:

Do you adjust PSI or nozzle type depending on the surface or how old the stains are?
Any tips on prepping surfaces—like grit, cleaning solutions, or methods—that make pressure washing more effective without damaging the surface?

Thanks in advance for any advice!
