SOURCE: I have a dewalt 3750

I worked at a tool rental center while attending college and learned many tips and tricks about Dewalt and other brand pressure sprayers. Your machine probably has a 13 hp honda and has max pressure of about 3500 to 3700 psi. Most of the problems that customers had were engine related due to severe working conditions including totally wet engine /plug, wet air filter, and or other problems that were easy to remedy. We would set the pressure regulator to minimum pressure and explained to the customer how to increase the pressure as necessary but only after the engine was completely warmed-up to running temp to prevent engine stall. Your machine has a throttle lever between the tank and carb that should be set to max if you are going to set pressure at or neer max range. Most cleaning jobs do not need much pressure. Use lowest pressure to get the job done. Your engine developes around 13hp at about 3600rpm. If you want to maximize the life of you sprayer, then use your machine at about 70% of capacity or about 2000 to 2500 range that will allow you to run your engine slower increasing lifespan. Your sprayer is likely rated at 4 gallons per minute so make sure that the tip is that capacity. The tip has the size stamped which would show the fan degree and flow in gpm. The wrong tip, say a 3.5 gpm will strain the engine to point of stop because the smaller tip increases pressure. Most engine stall is due to high pressure setting on new machines. Lower pressure when warming-up machine and use max pressure rarely when necessary to max life. Please email for other information/questions or simple tests to determine faulty parts, good luck.

SOURCE: cannot get it to uptake the bleach for spraying

On most pressure washers you wont be able to draw soap/bleach into pump unless you are spraying on low pressure.There is a valve on the inside of inlet hose fitting that closes when high back pressure is sensed.Would it draw bleach into hose when wand tip is removed?

SOURCE: low pressure

hi some valves at cat pumps need a 100 psi pressure to open and close correct. when there is air in the pump the valves wil not open and close till air is bleeded. take of highpressure hose, open watertap and bleed pump till no more air comes out. reconnect all hoses and try again. if there is no more air in the pump and its still not working, i should think its the pump.

Here is the long answer with everything we learned while using a power washer twice a day for years::
This assumes you did not turn power washer over or on its side to drain oil, or dirty oil will flow into carburetor requiring complete carburetor cleaning.

It sounds like could be one of the problems listed below or a combination of those things.
1) The exhaust is partially blocked. Check the screen covering exhaust port for carbon and dirt build-up. High-speed exhaust air must pass freely. We finally broke the exhaust screen out with a screwdriver to get our machine going one day.
2) Gas is not flowing freely to carburetor > under gas tank, find the rubber hose connected to carburetor. Pull off rubber hose and make sure gas flows freely. You can use this hose to drain gas tank of old gas ... and then put in fresh gas.
3) Carburetor is partially gummed up and engine cuts off when gas flow slows down. Buy some gum out, and then don't store power washer with gasoline in the tank. Or put additive in gas when storing machine.
4) The choke is letting in too much gas or not enough gas. Try different adjustments. The choke-lever on our power washer got so bad that we could not set throttle at full open or the machine would die. We still use the machine at 2/3 throttle, and then start it each time using WD-40 as described below.
5) Dirty air filter that won't let engine breath enough air to keep up with combustion. Take off air filter and see if problem persists.
6) The spark coil is going bad?? Change spark plug to see if problem persists. Is spark plug wire pushed all the way onto the spark plug?

Now the nitty gritty: we're gonna start that thing right now
7) Take off air filter. Spray WD-40 directly into carburetor. Yes, we use WD-40 every time to start my power washer, and we use the washer twice a week.
Spray in the WD-40, Pull the engine cord. The engine will fire on WD-40. Guaranteed.
Once it starts, keep spraying WD-40 directly into carburetor to keep engine going.
If engine will not fire and keep going on WD-40, then your spark is suspect.
If your engine fires and runs on WD-40 but dies without it, then your gas supply or carburetor are suspect
8) Carburetor problem >>> try Gum out >>> and then take machine to small engine repair shop
9) Spark ... take out spark plug. Put spark wire back on. Hold spark plug by spark wire. Touch metal threads of spark plug to metal opening where plug came out. Metal to metal. Pull back start cord and look for spark between the metal.
If you have no spark, then spark coil is bad >>> take machine to small engine repair shop

Why is my washer saying low water pressure. How can I fix that without have someone come out to repair it


It depends on the cause of the water pressure issue. I'd first check your incoming water to the washer. Turn off the inlet shut-off valves and disconnect the hoses. Check the hose filters and the inlet valve filters. Remove any debris. Next put a large bucket under the shut-off valves and open them fully for a minute. Check how much water flows into the bucket. If very little water was in your bucket, you'll need to check where the restriction is in your water lines. (The water pressure needs to be sufficient to fill the washer in about 8 minutes. Depending on your home, you may need a professional to check the water at your water connection to the city or at your well pump.) Empty the bucket. Replace your inlet hoses at the valve side and repeat the test. If you are getting low water flow with the hoses in place, replace the hoses. Some hoses have a "anti-flood" feature which restricts the hose if there is a problem. (I've seen the hot water flow rate to the washer significantly decrease due to the hose blocking the flow. The cold water hose was replaced at the same time to avoid it failing in a short time.)

Next check that the drain hose isn't below the level of the water in the washer. This can cause siphoning and empties the washer as fast as it fills.

If the water pressure is still low after testing these items, the problem could be the inlet valves on the washer or the air pressure at sensor that detects the water flow. On some washers, you may be able to remove the debris in the air tube. However, if there is a pinhole, that part will need to be replaced.

I hope this helps.

F20 error code


copied from the net..............


The "F20" fault code is indicating NO WATER IS BEING DETECTED ENTERING THE WASHER OR THE PRESSURE SWITCH IS NOT TRIPPING OR SENSING A TRIP.

If there is no water in the unit:

Make sure that both valves at the water source(s) are turned on all the way and water enters.

Check for plugged or kinked inlet hoses or plugged screens in the inlet valves.

Verify inlet valve operation.

If there is water in the unit:

Verify drain pump operation.

Verify that the pressure switch hose is in good condition and properly connected to tub and pressure switch.

Verify there is not a siphon problem.

Press STOP twice to clear the display. The machine will drain for 3 minutes before unlocking the door.

Unplug washer or disconnect power.

Verify wire harness connections to inlet valves, pressure switch, drain pump and Central Control Unit (CCU).

Check all hoses for possible leaks.

Plug in washer or reconnect power

Verify pressure switch operation.

I recommend calling a service technician to diagnose and repair your washer if water will entering the machine and not siphon out.

HOW DO I DRAIN THE WATER FROM MY HP WASHER FOR WINTER


What I've always done is just disconnect the water hose then start the washer and pull the trigger till no more water comes out. You don't want to run it very long at all after there's no more water though, you can quickly overheat the pump if it is ran without a water supply for too long. I've been doing this for the past 3 years with one of my washers and haven't had any problems with the pump.

Where is the filter in washing machine


Start by turning off the hot and cold water faucets that are connected to your washing machine. This will stop water from running into your washer so you can disconnect your water inlets without flooding the house! To relieve any built-up water pressure, pull the knob out on your washer that starts the washing cycle for just a few seconds. Now it's time to unplug and disconnect your washing machine. First, unplug your washer from the electrical outlet. Next, use a pair of pliers to unscrew the hose fittings on the back of the washing machine. There will likely be some water left in the hoses, so you will want to have a hose or a bucket handy in order to catch and clean up any spillage. Now it's time to break out the water-resistant vacuum. Place the vacuum over each water inlet. As you turn on the vacuum, tap on the inlet a little with a plier in order to free any debris or sediment that may have lodged in it. Continue vacuuming until the inlet is clear, then repeat on the second water inlet. Now that you're done clearing out the filters, it's time to reconnect your washer. Using your pliers, reconnect the correct hose to its inlet and make sure to tighten them properly. Don't forget to double-check to see if there are any leaks. If you find any, re-tighten accordingly. After that, all you have to do is plug your washer back into the outlet and you're ready to go. You've successful cleaned out your washing machine filter!

Hi

You'll need to check for the water inlet hose, the water inlet valve and the pressure/water level switch assembly. Inspect the inlet hose coming to the washer for any blockages. If the hose is not clogged then check the water inlet valve for any clogs, if the water will not even fill for few seconds then certainly the water inlet valve is bad and should be replaced. You can also use a multimeter to check continuity on inlet valve. If you don't get any value on the multimeter then you'll need to replace the water inlet valve assembly. However, if the valve is fine then the pressure/water level switch assembly should be replaced. Hope this helps... Please post back if you need more information.

the water pressure and drain hose have alot to do with your problem. when a washer fills up all it does is opens the water valve. if there is not enough water pressure or the water is not turned on all the way, the flowmeter ( does exactly what the name says) will tell the washer there is not enough water coming to it while the valve is open. the drain hose is important because if it is to low it will syphon the water out of the machine while it is filling. when that happens the pressure switch will read that the water level is not rising and can cause you problem. if the drain hose is sitting all the way down in the drain pipe this will also happen. if the drain hose and water supply are ok i would start looking at the inlet valves please message me back with any further questions and please remember to rank how this opinion has helped when our chat has concluded in full Thanks again Rick

KOHLER HYDRO 13 When pressure washer engine is


first sheck the inlet screen where the garden hose attaches,if there is water flow then see if it has a manual pressure regulator, this will be a knurreled knob somewhere on the intake manifold of the pump, ifyou have one, turn it clockwise and see if there is a difference. If still no luck, disconnect the high pressure hose from the pump, start it and see if warer flows at that point, Your gun may be clogged or your hose may be delaminating on the inside and need to be replaced. If all this fails I suggest you bring it to an expert. These pumps can require special tools and expertise to repair internally
