Problem description is very vague. The only thing for sure is that water seems to be coming out at the wrong place. Common problem could be related to improper storage. All water, or as much as possible, should be removed from the pump before cold weather storage. Many pumps are made from cast aluminum, which can easily crack or split from winter storage if enough water remained in the system during freezing weather. If it is an external part, such as the inlet or outlet tube, check the manufacturer for a replacement part, since these are sometimes replaceable. Another possibility could be a loose fitting on the pump. There is also an "O" ring on the connection to the outlet tube on the hose end. Check to make sure it is still there and not broken or crushed. Many hardware stores have "O" ring kits. It would be helpfull if you could pinpoint the source of the leak. Always separate the gun and hose from the pressure washer to drain out any remaining water. Freezing isn't the only problem since you could have hard water that will leave mineral deposits when the water evaporates. This, according to some manufacturers will not be covered by the warrantee so I guess is should be something to avoid. Good Luck.

Water will not shoot out....took the hose off and it still doesn't work

If this model has a quick disconnect coupling for the pressure hose opposite of the sprayer wand at the pump, remove with a wrench. Hook up the water hose, turn on he water , but don't start the engine. If it has a clog this will flush out the clog. Replace the coupler and hose, turn on the water first before starting the engine. If the pump builds pressure it will make the motor bog down slightly. If there's no change in the sound of the engine with water turned on, the pump will be damaged. If the motor bogs off and on and water sprays on and off, means there is an air leak in the pump. If the pump does not work at all with the water turned on, the pump will be burned up. Please don't take this in offense; but I've seen many power washer pumps damaged because the water was not turned on before starting the engine. Try these few steps and let me know if you get any pressure at all, if so it's probably an air leak. Good luck!

My rodeo started shooting steam out i filled it with coolant and during my 1 mile trip home water was pouring out from underneath,i poped hood,cap was on but steam was coming from below engine,help

Hi there,

Hopefully there is a hole in one of the hoses (least expensive).

No matter what, you need to find the source of the leak. A flashlight will be useful.

When the engine is cool, pour water in the radiator. You shouldn't need to run the engine.

When it starts dripping, look for the leak on:
  • The radiator
  • Large hoses leading to and from the radiator
  • Heater hoses (smaller leading to firewall)
  • Water pump (on the engine)
Once you find it, the severity and type of problem will dictated whether to fix or replace the damaged part.

I have no hot air coming out off my heater

You need to change the heater core nothing else will help. You could try charging the heater core with water from a garden hose> Shoot water to the heater in to the 2 hoses next to ur car battery. Make sure u dont shoot water in to ur engine the heater core is inside ur car not under the hood, u just have 2 hoses going under the hood. after u see clean water coming from the heater should start working better.

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

What`s the function of starboard outlet spout ?

The water squirter out the side is there to show you that there is cooling water going through the engine. If the outlet spout stops shooting water out the side you need to stop the engine and investigate. I have had mine stop shooting water. I stopped the boat and blew air through the hole backwards to clear the tube. One time I had to pull the hose off the motor(where the squirting water enters a hose to the outlet spout) and push a piece of wire into the engine outlet hole to clear it. Fortunately , the motor was never in any danger of overheating only the wizzer hole was blocked , water was still cooling the motor. Again if the outlet spout stops shooting water turn off the motor and make sure water is entering and cooling the motor.

Radiator is not holding water looks like it is shooting out the back side of the engine but i cant tell which hose it is coming from. please help

Back side of the engine would indicate heater hoses going into the heater core. Replace both heater hoses - they are the same age and if you replace only one the other one could go any time.

The water valves might be going bad, or there is a clog in the hoses. Also check the water pressure going into the washer.

Bucket fills up instead of water flowing out hose

There must be a blockage in the hose causing the water to back up and flow into the bucket. Try pushing a flexble peice of wire through the hose to unblock it.
