Wy mydewalt pressure washer lose presure? - Dewalt 3800 PSI Pressure Washer

I have one that will shut off pressure when the water supply varies. Check your water tap, make sure all your connections are TIGHT. If not they will suck air and interrupt and pump cycle. Use new hose washers on everything. The engine (mine is Honda) will also buck in response to varying flow demand. It has an auto-close spring/lever to prevent it from overrunning if it loses incoming water. Good luck.

Most likely broken or suck unloader valve

The head probably needs some cleaning. I use a spray bottle of general cleaner. Then I'll shoot some wd40 in the head.

Check for your catalitic muffler must be stuck that is wy the glow plug light is going on and then you louse presure

sounds to me like some of the jets in the cab are plugged remove the carb and clean the jets and passages

there should be a low presure tip for dispensing wash cleaner or if you have an adjustable wand turn it to low presure setting also make sure the suction tube is open some have a adjustable filter...good luck

I like http://www.ppe-pressure-washer-parts.com/excell-vr2522-replacement-parts-pump See pump upgrade and compare to rebuilding. Another good site is www.pressure-washer-parts.com. Piston seals usual begin by overheating from excessive idling. You might add a thermostatic relief valve to help this.

it just the presure building back up ,it will last years doing this,i would not worrie as replacing the presure pump will only be a temp fix and it will do it again ,most washes do this after a year or lots of use.

Hi

Just try the following steps

• Inspect the water supply connections
• Inspect the drain hose
• Inspect the water pump
• Inspect outer tub for cracks or corrosion
• Inspect the tub seal
• Inspect the tub bearing

Good luck

Try to release the pressure from the wand. Take of the tip if you have to. If that doesn't work take the spark plug out and pull, oil may have gone into the valves. Clean the plug and put it back. It will clear, the smoke that is. Lemme know. Please rate me
