20 Most Recent Briggs & Stratton Prosumer 20324 Gas Pressure Washer - Page 3 Questions & Answers

The pump is bad and needs to be replaced. you have done all the test. On the Briggs they do have kits to rebuild the pump on your system you can just go to there website and get the rebuild kit. It is safer to go through them because they have jsut started producing the rebuild kits, and other companies have tried to copy them, but there kits are worthless. Please rate

PRESSURE WASHER WONT TURN ON

force feed the pump with water it sounds like its sucking air rather than water if no leaks check the 6 valves regards

check your fuel mixture settings on the unit. What is the model of the engine?

If you ran the pressure washer without water running through it on startup you probably got your pump.You are supposed to engage the trigger on start up with water running through it so as to release the pressure off the pump so it will start easier. Hope this might help you.

the only times Ihave seen this happen is when the pump seals were on the way out and water is pressurising the pump.the other thing that comes to mind ,you said you had just changed the oil , did you use non foaming oil? if not theoil will expand as it aereates but then it cenrerally looks milky but is does come out the breather etc

Look for a drain plug on the base of the engine.
Take the fill cap off also, and it'll drain easier.

Dear Davidpaulson,
There are many reasons why there is no pressure. The simplest one is try a new lance. The lance you say it is not blocked, but it could have a wider hole with wear and tear.
The second most possible reason is, faulty valves. The suction valves are the most that give low pressure when they are faulty. To check the suction valves, put on the machine in the normal way and as it is working, disconnect the water supply. Than check if air or water is blowing out from the inlet. This is not 100% but you can have a picture of the function of the suction valves.
On the other hand if you do this exercise with the outlet, after removing the gun, you can check for the delivery valves. If you feel suction at the outlet, than the delivery valves can be faulty.
If all is correct, than there must be a fault in the swash plate. This could become loose and so the pistons will stop moving. Also another fault could be broken springs.
Also if the machine is leaking, the high pressure and low pressure seals are damaged. This also lowers pressure.
Other faults are related to the famous spill valve. Also faults could be to internal water leakages, due to corrosion in heads. Finaly I like to add that a faulty electric motor, could also not deliver enough rotation and power, and this also reduces pressure. This could be rewinded or changed for a new one.

Hi

First check compression.Priming the engine for few times.Check the air and fuel filters.Check the flyweel keey not to be shatered off(timing).Start the engine.If the engine only runs the gas from the cilinder you puted inside you have a fuel delivery problem to find and fix.The spark at the plug has to be blue!

Likely either the engine is flooded or low compression.

A simple go no go compression test is remove spark plug and press a thumb or finger firmly over the plug hole and crank engine. It should forcibly push your finger and make a loud PFFfft sound. No or little sound equals insufficient compression.

If the push rod was not bent, there was no reason to replace. If it was bent then I question how you set proper valve lash with new pushrod as the typical cause for a bent rod is a displaced valve guide.

If compression is OK then likely it's simply flooding and you have a carb float/inlet needle issue. Crank engine, remove plug and if it's saturated with fuel then it's flooded and a flooded engine will not fire, even with starter fluid.

Comment for further assistance.

Check the gap between flywheel and coil

Jeremy, It very well could be that the filter was oiled when cleaned or from OEM. ck here... https://www.youtube.com/watch?v=vSA3ooVIhXY Best to you.
