Craftsman 471446070 high-pressure washer Parts

On a Craftsman pressure washer like model 471446070, the model number is printed on a rating label (sticker or metal tag) attached to the frame. Most often, you will find it on the top of the lower frame near the rear, or on the top or back of the upper frame.

Common places to check first

Look for a rectangular label with the model number and other specs (sometimes also a serial number). Check these spots:

• Top of the lower frame, toward the back
• Back side of the lower frame rail
• Top crossbar of the upper frame (near the handle)
• Back of the upper frame (behind the engine/pump area)
• Near the wheel axle bracket or base plate area

Quick tips to make the label easier to read

Dirt, detergent, and sun fading can hide the print. These steps usually help:

• Wipe the label with a damp cloth and mild soap; dry it fully
• Shine a flashlight across the label at a low angle to highlight embossed print
• Take a close-up photo and zoom in (or increase contrast) to read faded text
• If the label is scratched, look for the model number stamped into nearby metal parts

What the model number helps you match

Having the exact model number (including any extra digits) helps us match the correct parts list and diagrams for your unit.

You need	Why it matters	Example
Model number	Identifies the exact pressure washer version	471446070
Serial number (if present)	Helps narrow production run changes	Varies
Engine model (if separate)	Helps match engine-specific parts	Varies

Why it matters

Pressure washer parts like the pump, unloader/thermal relief components, hose fittings, and spray gun connections can vary by production run. Using the correct model number prevents ordering the wrong replacement.

Craftsman pressure washers (including model 471446070) are not covered by a single, universal lifetime warranty; warranty length varies by the specific pressure washer and by major components (such as the frame, pump, and engine). For the exact coverage on your unit, match the warranty to your model and purchase date.

What to expect for pressure washer warranty coverage

Warranty terms are typically split by component, so one part of the machine can have longer coverage than another.

Common coverage breakdowns you may see:

• Frame or structural components: often longer coverage than wear items
• Engine (gas models): often a separate term from the rest of the unit
• Pump: may have its own coverage window
• Hose, spray gun, tips, seals: commonly treated as wear items
• Normal wear, misuse, freezing damage: commonly excluded

How to confirm the warranty for Craftsman 471446070

Use these checks to line up the correct warranty statement with your exact product.

• Locate the model number 471446070 and any type/serial information on the data label
• Find your proof of purchase (date matters for coverage)
• Compare the warranty language for the pressure washer versus the engine (if gas)
• Note any maintenance requirements (oil changes, winterizing, pump protection)
• If you are missing the label or paperwork, use how to find your appliance model number (and what it means for parts) to confirm you are referencing the correct model

Quick guide: what’s usually covered vs. not covered

Category	Typically covered	Typically not covered
Defects in materials/workmanship	Yes (within term)	No (outside term)
Wear items (tips, O-rings, seals)	Sometimes	Often
Damage from freezing or improper storage	No	No
Commercial use	Sometimes reduced	Often excluded

Why it matters

Pressure washers combine high-pressure water flow with mechanical and (sometimes) engine systems; warranty terms often differ because pumps and engines have different failure patterns and maintenance needs.

On a Craftsman pressure washer model 471446070, replacing an O-ring usually means removing the quick-connect fitting, sliding the old O-ring out of its groove, and pressing a matching new O-ring fully into place so it sits flat and seals.

Before you start (safety and setup)

• Shut the engine off and let it cool.
• Turn off the water supply.
• Squeeze the trigger to relieve pressure in the hose and wand.
• Disconnect the garden hose and high-pressure hose.
• Work over a towel so the small O-ring does not roll away.

Steps to replace a quick-connect O-ring

1. Inspect the fitting: Look inside the female quick-connect coupler (or on the male plug) for a cracked, flattened, or missing O-ring.
2. Remove the old O-ring: Use a plastic pick, toothpick, or a small flat tool with taped edges to lift the O-ring out of the groove.
3. Clean the groove: Wipe out grit and scale; debris can cause leaks even with a new seal.
4. Lubricate lightly: Apply a thin film of silicone plumber’s grease (avoid petroleum grease on many rubber compounds).
5. Install the new O-ring: Stretch it just enough to slip into position, then press it evenly into the groove with your fingers until it sits flush.
6. Reassemble and test: Reconnect, turn water on first, then run the washer and check for drips at the connection.

Choosing the right O-ring

O-rings are not one-size-fits-all. Match these details:

• Inside diameter (ID)
• Thickness (cross-section)
• Material (common: Buna-N/NBR; sometimes Viton)
• Location (hose coupler, wand inlet, pump outlet, detergent injector)

Where it leaks	Most common cause	What to do
Quick-connect coupler	Nicked or flattened O-ring	Replace O-ring; lubricate
Wand to hose connection	Missing O-ring in fitting	Install correct size O-ring
Pump outlet fitting	Debris cutting the seal	Clean groove; replace O-ring

Why it matters

A good O-ring seal prevents air leaks and water leaks that reduce pressure, cause surging, and can damage fittings over time.

Yes, it’s worth repairing a Craftsman 471446070 pressure washer when the problem is a low-cost, high-impact fix (clogged nozzle, leaking hose, worn seals, dirty carburetor). If the pump or engine has major internal damage, replacement usually makes more sense because parts and labor can approach the cost of a new unit.

Quick decision checklist (repair vs. replace)

• Repair if the washer still starts, builds some pressure, and the issue is a wearable item (nozzle, hose, unloader valve symptoms, O-rings).
• Repair if you can do the work yourself and only need basic tools.
• Replace if the pump is cracked, the engine has low compression, or the unit has repeated failures.
• Replace if repair cost is more than 50% of what you would pay for a comparable new pressure washer.
• Replace if you need it for frequent use and downtime costs you time or money.

Common “worth repairing” problems

Symptom	Most likely cause	Typical fix level
Low pressure	Clogged nozzle, air leak, worn seals	Easy to moderate
Surging pressure	Unloader sticking, nozzle mismatch	Moderate
Leaks at connections	Worn O-rings, loose fittings	Easy
Won’t start (gas models)	Old fuel, dirty carburetor, fouled plug	Moderate

What to check first (fast, practical steps)

1. Verify water supply: full flow, no kinks, clean inlet screen.
2. Try a different spray tip; a partially clogged tip can mimic pump failure.
3. Inspect for suction-side air leaks (loose garden hose fitting, cracked inlet).
4. If it’s gas-powered: drain old fuel, check spark plug condition, and confirm the choke works.
5. If pressure surges: suspect the unloader valve or a restriction at the nozzle.

Why it matters

Pressure washer repairs are usually economical when they restore performance with minimal parts and labor. Major pump or engine failures often turn into a cost trap, especially on homeowner-grade machines.
