Hi and welcome to FixYa, I am Kelly
It took a bit of research but I think I found the parts list here: (
There WAS a kit for this pump that the part number is B4182 and is no longer available. (

The pump parts list you should be looking at is 020303-2
There are oil seal and water seal kits here: (Half way down the page)

You said you got a milky color then lost pressure. Until you tear it down you will not know if it is the water seals or the oil seals you need. Personally.... I was going to repair it for you I would install both sets of seals. What will be frustrating about the repair process is you usually do not get it going again on the first try. You will end up ordering other o-rings to complete the repair. If you get it by the 3rd attempt your doing great!

What may have caused this problem a lack of water supply due to a restriction somewhere. If for example there is an inlet screen to the pump and the supply line was mostly blocked the pump will cause a vacuum and draw the seals inward into the pump. ( I think this is what happened to your pump) Just make sure to check for any inlet strainers or screens. Who knows you might get lucky and just have to clean the screen / strainer.

Hi. I think the problem may be called either vapor lock or cavitation, or it could be called something else, but the solution is to take the wand apart in the center and let the trapped water escape, then putting it back together before re-engaging the lever.

After attaching and turning on water from hose, water came pouring out the bottom of the machine. It worked fine last week. Please advise

IF it was not subject to freezing weather, check the input connections on the pump and make sure that the washers are present on the hose connection.

The pressure washer leaks from inside casing letting out water/soap might be affecting pressure of hose?

If your part of the country reaches freezing temperatures during winter, the pump probably froze. This can cause cracks to brass and (especially) aluminum pump heads. It is worth opening up the case; sometimes I find loose fittings (caused by freezing) which can be tightened up and everything is fine. If it is not freeze damage, the check valve may have gone out on the soap injector, causing pressure to back flow through the inlet barb. Otherwise, you may have a worn/leaking pump seal.

This is a consumer (throw-away) pressure washer. If it's not a loose fitting which can be tightened, the unit is probably not worth fixing.

Is the pump seal bad when doesn't spray /pump well?

The sign of bad seals are water leaking out of the bottom of the pump. The high pressure seals get bad enough the low pressure oil seals will fail as well and water will get into the crankcase.
Weak or fluctuating pressure is a sign of a problem with your check valves or seal problems with your unloader valve.

Leaking from motor

Water Inlet Valve

If the dishwasher is leaking water the water inlet valve might be defective. If the water inlet valve sticks open, it will allow water to fill the dishwasher continuously. Some customers report that they see clean water filling the bottom of the dishwasher after it's been sitting all night or for a couple of days. If this happens, turn off the water that is supplying the dishwasher. This is normally a valve under the kitchen sink. Then, replace the water inlet valve, it cannot be repaired. The water valve needs at least 20 lbs pressure to shut off properly. If your water pressure is to low replacing the valve may not solve the problem.

Center Wash Arm Assembly

If the dishwasher is leaking water, the center wash arm assembly might be cracked or split. This can allow a jet of water to spray toward the door seal, causing a leak. If a crack or split in the center wash arm assembly is found, replace it. There isn't any glue that will hold the part together inside the dishwasher.

Lower Wash Arm Assembly

If the dishwasher is leaking water the lower wash arm assembly might be defective. If the lower wash arm has a crack or split on the end, it can force water to spray directly toward the lower part of the dishwasher door. Then, the water can be forced under the door and onto the floor. Check the lower wash arm for any cracks or splits and replace it if necessary. Also make sure the screws are tight in the wash arm support. If the screws are loose, water can spray out the side of the pump and cause a leak.

Upper Wash Arm Assembly

If the upper wash arm assembly is broken or cracked it can cause water to spray very forcefully toward the seams of the door, causing a leak.

Door Seal

Every dishwasher door has a door seal. If the dishwasher is leaking water, it might be that the door seal is defective or worn out. Try closing the dishwasher door on a dollar bill and see if the door seal is making good contact all the way around the door. If not, replace the door seal. If the door seal is good or has been replaced and there is still a leak check the door hinges. If the hinges are bent the door will not close properly and the hinges will need to be replaced.

Dishwasher Door Gasket

Coleman 2400 PSI Pressure Washer - WATER LEAKS OUT = ?!? Help me please!!! ((-:

Usually, there are spaces between the pump and head portion of the pump. This space is not sealed and will allow water leaking past the seals to come out. There may be a seal kit available, however I have had better luck just changing out the whole pump. There are many available on ebay. Search for one that will use same mount and hoses. Once the seals are gone, the pump will never be the same (may nickle and dime you the death).

Water leaking out of bottom of washer

It sounds like water was left in the pump and i froze over the winter and cracked the pump housing. You can try taking the gun hose off and blow compressed air where the hose hooks on to blow waterwater out of the pump and dry the bottom. Then put some apoxy on the crack to seal it.

No high pressure water out of the gun ,unit runs fine just no pressure

Hi and welcome to FixYa, I am Kelly.
First off without a model number this is a GENERIC response. There is a knob on the output line of the pump that adjusts the output pressure. This is called the un-loader / bypass valve. Underneath the knob there is usually a knurled locking nut that prevents the knob from rotating during use. This valve gets stuck from either debris or corrosion. Remove the valve and clean up the inside of the housing along with the spring and the seals of the valve stem. A tightly rolled but shorter piece of 150 or above grit sand paper works good for this as you rotate the sandpaper in the hole to clean the corrosion out the housing. Use an air or water hose to flush out the sand paper debris before re-assembly. BEFORE you slide the stem back in place... Lubricate everything with some #105 WHITE GREASE. (Small tubes are available at any automotive parts supply.) After a very liberal lubrication of the housing springs and seals with WHITE GREASE, re-insert / install the un-loader bypass valve. Do not forget to lock the nut on the bottom of the knob so that it does not come off during use.

NOTE: If you have a smaller unit that does not have a visible un-loader / bypass valve it will be located just before the pressure hose connection on the output side of the pump housing under a fairly large screw in cap.

Before you test the unit pour at least 2 oz. of engine oil into the water connection knowing full well that when you test the unit your going to get some oil and white grease out of the unit.

Connect up the hoses and give it a full test. This usually brings them back to life.

No pressure from pressure washer

Do you plan on doing the repair yourself. I need more info, when you supply water to the pressure washer, pull the trigger to purge air from pump, and start the machine. Do you see water coming out from the bottom of the pump? Do you hear the pump working or is it quiet. If you hear a cycling pattern or hear the pump trying to push the water out but it isn't, then you may have a blockage inside the trigger or the spray tip. If the pump isnt building pressure then you may have a pump problem. A stuck check valve, cracked plunger, bad seal, or could be air bound.

Washer leaking water from bottom

You may want to check the seal at the bottom of the agitator, there is a o-ring that keeps the water in the drum from leaking through the agitator as it spins. This is a cheap seal and will wear over a period of time from exposure to bleach and detergent. You need to take the agitator apart and remove it from the drum and you should see this seal at the base of the agitator were it meets the drum.

Replace the seal and reassemble, take the metal casing off the washer and fill the drum with a little water, wait, and see if the water is leaking under the drum. If no leak, try to reassemble and run the washer. If is still leaks then check
