Answers :

There are two common issues that will cause what you are describing. What you need to do is run the machine until it dies as you are describing. Then pull the spark plug and check for spark. If you do not have spark you have a failing stater. It is very common for this problem to only show itself after the machine warms up. If you find that you do still have spark try removing the gas cap and restarting. It is also common for a vacuum lock to occur due to the seal on the gas tank cap. In most cases one of these will be your issue. If not feel free to contact me at 800.247.8103 and I will help you to troubleshoot the issue further.

Hi I have a Troy-Bilt Pressure washer 2200 psi model 20292. I've used it only 4 or 5 times. It ran great for an hour today then it lost pressure. Seems like the pump is not working.

I HAVE A BRAND NEW TROY-BUILT 2600PSI pressure washer. I have used it twice for about 1/2 hour each time. It worked perfectly. I tried to use it today with everything hooked up perfectly. The Honda engine started perfectly; how ever when I squeezed the wand trigger, the engine instantley died. I let the engine warm up and slowley pushed the choke in.

I have a Briggs & Stratton Pro 3400 pressure washer that I got new last year and used for maybe 5 hours and it worked great. Have had it stored since then with stabilizer in the gas (I didn't run it dry) and now it won't run for more than a minute or two without dying. A dealer said it was probably bad gas and I now know that even with the stabilizer I should have run it dry last year before storing. Everything is like brand-new including plug and air filter so it must be the gas/carberator gunk

I have an electric power washer model PW181000AV with about 25 hours on it. Got home from my winter retreat and used the power washer about 1/2 hour on the driveway. Everything worked fine.

Hi, I have a Karcher K3 pressure washer. 18 months old, used maybe 6 hours total. For the past 3 hours of use the compressor/pump seems to cycle audibly but pressure at outlet hose seems constant, hence I did'nt worry. Now it does not start with switch on. I now hear a buzzing sound from the unit. The unit was last used 6 weeks ago.

I have a Dewalt 3800 pressure washer fitted with a 67DX39G11 pump. Started unit up for the first this year, has pressure for 15 seconds then nothing.

I have a McCulloch FH160B power washer and it no longer builds up pressure. I haven't used this very much at all. I tore it apart and cleaned everything I could find. When i pull the trigger for the spray nozzle, I get line water pressure. When I release the trigger, the power washer sounds like it starts to build up pressure. When this was working correctly, the pump would shut off when the trigger was released. Any suggestions?

The pump switch they spoke of is an internal switch. It is activated by a valve so that when you let go of the trigger, the machine shuts off. This valve is stuck or the switch is bad. Usually the valve is the problem. I would go to Sears and get ... Pressure Washers

I have a DPH3800 Dewalt pressure washer and the soaper isn't working properly. Right tip is being used but when trigger is not pressed it puts water into the bucket.
