Question about Briggs & Stratton Prosumer 20324 Gas Pressure Washer

Open Question

Very little water pressure coming from pump.

The engine runs just fine on my machine. The problem is that I have little water pressure coming from the pump. I have checked to see if anything was clogging the hose, gun, and the tip every thing looks clear. When I remove the gun from the hose and even when I remove the hose from the pump there is very little pressure coming from the pump.

Will start and run fine water comes out but has no pressure


Maybe bad pump. Remove wand and wand hose, run machine with water in. High pressure water coming out of wand/hose connection, bad wand or hose. No high pressure water, bad pump, replace.

The engine runs but the water will not come out under pressure


You must have blown out the cones (thats how the water gets compressed inside of pump) in the water pump-

You could try this though on the back of the washer right on top of the water pump is a black knob about the size of your hand that knob will adjust the pressure try turning it and see although I doubt that is the problem-

A pressure washer is not like a compressor you HAVE to pull the trigger every minute NEVER let it just sit there running without pulling the trigger to release the pressure that Dewalt 3800 psi washer you have is a great machine in fact we own 4 of them and they are pretty powerful and easy to damage if left running alone.

Miele CVA615 won't produce steam or hot water. Machine makes a mechanical noise like it's trying but no water comes out. The expel air indicator was on and this preceded discovery of the issue. Steamer...


Trey -
It sounds as if the water pump has gone bad. If the machine will not put water out of the hot water spout or the steam spout, and there is no water in the base of the machine (leaking from pump) then the pump is not putting out any pressure. The sound you hear is the pump running - but no pressure behind it.

Troy-bilt presswasher that is running fine but has no pressure from the unit and any water that is flowing thru is very hot when the engine is running.


Hello,

Your machine is air locked. Air in the supply line reaches the pump and the pump cavitates, allowing very little water to get by. Since the pump is just chewing air, it is getting very hot, producing the result that you see.
With the engine off, turn on the supply water and allow it to flow through your washer. You may need to lock the trigger on the wand in the open position, or hold the trigger down while purging the supply line. Make sure that there are no kinks in the supply hose and that any loops in the hose are straightened out. Raise the hose above your waist and walk it the length of the hose to the washer, forcing any air pockets through the hose and through the machine. This entire process will take about 5 minutes or so.
Release the trigger, start the machine and get to work. If the machine doesn't put up enough full pressure when you crank it, try cranking it while holding the trigger open. Sometimes the overpressure valve sticks, and can prevent full pressure from being reached. Holding the trigger open bypasses this issue, but doesn't repair it.

Best regards, W/D--

Engine runs , not getting any water flow when trigger pressed.


Disconnect hoses.
Look for kink in water hose.
Check incoming water connection for filter washer
Replace filter washer
If you don't have a filter washer, put one in.
Hook up water, and turn on
Water should come out other side of pump.
Turn on machine.
Do you get pressured water out of pump.
If no pressure, then pump is suspect
Hook up washer hose without gun
Does pressure come out of washer hose
Finally, the gun trigger may be bad.

We had to buy guns now and then.
Search for pressure washer guns
Following link shows guns we used:

My pressure washer is a G 2500 oh n i have no pressure coming out, it turns on but no pressure.


Good news, your engine runs
But your pump may be bad

Here's how to test your pump
Check oil as outlined lower down
Disconnect the washer hose and gun
Connect water hose and turn on water and water should pass straight through the pump
Look for clogs in the hose-end where water hose connects to machine

Turn on machine and see if water shoots out pump
If water shoots out of pump, but no water shoots out of gun, then you may have a 'mud-dobber' wasp clog in your washer line or gun

Look for clogs in the end of each water connection.
Now connect washer hose without the gun, tun on the machine, and see if water shoots out of washer hose
Finally, the gun trigger mechanism may be bad
I don't know which gun you have ... but we replaced guns on our machine now-and-then ... google-search power washer guns for a replacement

Check your pump oil
Pump oil is SAE20 or SAE30 non-detergent motor oil
Pump should be no more than 1/2 full of oil
Use plastic hose to drain pump oil
Do not turn machine on its side or turn machine over or engine oil will run into carburetor

Honda excell pressure washer does not have pressure


if the machine is running on suction, ie sucking out of a barrel there may be an air leak on the suction hose or pump. it will pull air easier than pulling water .

put the machine under mains water pressure, hose pipe straight from tap to pump.
check all around the pump and inlet pipes for leaks.
if water leaking this needs rectifiying for it to work on suction.
run the pressure washer while on mains pressure with the hose on, does this make a difference?

if not then probably the unloader is stuck in the pump head. remove unloader , clean and replace it
parts breakdowns are available on the internet for your machine.

possibly valves stuck, or the valve springs have broken, seen this quite few times on these machines. if so replace springs .

These sort of machines do not last very long anyway, about 50 hours use if your lucky.
