The unloader valve controls water pressure in your Craftsman pressure washer by diverting flow when you release the trigger. When pressure pulsates, won't build, or gets stuck low, the unloader valve assembly or float part is usually at fault. Craftsman pressure washers use specific float and valve configurations depending on your model — getting the exact OEM unloader valve or replacement float ensures proper pressure regulation and prevents pump damage from prolonged bypass mode.
Float assemblies inside the unloader valve can stick, corrode, or lose calibration over time. A worn float won't trigger the valve to shift, leaving your pump running constantly at low pressure. OEM Craftsman unloader valve kits come with all internal parts including the float, poppet, and springs — replacing the complete assembly is more reliable than attempting individual float repair.
Use your Craftsman model number to confirm the unloader valve assembly type and float configuration. Craftsman pressure washer valve and float parts are available for both gas and electric models across all Craftsman pressure washer generations. Enter your model number to find the correct replacement unloader valve.
The unloader valve diverts water flow back to the pump intake when you release the trigger, dropping pressure quickly and protecting both the pump and your hands from dangerous pressure spikes. The float inside the valve senses pressure drop and triggers the internal poppet to shift, opening the bypass port. Without a working unloader, the pump would cavitate or the hose pressure would remain dangerous even with the gun released.
A failing float shows itself through pulsing pressure (float sticking and unsticking), constant low pressure even with correct nozzles (float won't trigger the shift), or a mushy trigger feel that won't regulate pressure properly. You may also hear the pump cavitating or working harder than normal. If the pressure gauges show erratic readings or the pump keeps cycling on and off, the float assembly is almost always the culprit.
OEM Craftsman unloader valve kits include the float, spring, poppet, seal, and housing as a complete assembly. While individual floats are sometimes available, the valve seat and poppet often wear together with the float, and aftermarket float replacements have high failure rates. Replacing the complete OEM unloader valve assembly is the reliable choice and usually only $20 to $40 more than a float-only part.
Locate the rating plate on your Craftsman pressure washer — usually on the engine (gas models) or housing (electric models). It shows the model number (often starts with a year or series code), PSI rating, and GPM. Write down the full model number and enter it into the Repair Clinic model lookup tool to confirm the exact unloader valve assembly and float type for your machine.

On Craftsman pressure washers, look for the model number on a label attached to the frame near the engine, or check the sticker on the pump housing. Clean away dirt or grease so you can read every letter, number, and separator accurately. The model number identifies the complete pressure washer, not just the unloader or another individual part. Type it into our model number lookup and the catalog narrows to parts made for your unit, including valves, pumps, hoses, and other associated parts. Using the full number helps you select compatible parts quickly and avoid ordering by appearance alone. That means fewer wrong orders and a faster repair.
