Samsung Dishwasher Water Inlet Valve
Samsung dishwashers (DW model series) integrate SmartThings diagnostics and features like WaterWall spray technology and Zone Booster nozzles, but when the water inlet valve fails, you need specific Samsung procedures — not generic dishwasher advice. This guide covers the DD62-00067A replacement with Samsung-specific access procedures, the DD-prefix part numbering system, and the diagnostic steps that help you confirm the failure before spending money on parts.
Symptoms That Indicate Water Inlet Valve Failure
- Dishwasher does not fill — no water enters the tub. Samsung error code 4E displayed
- Slow fill — 10+ minutes instead of 2-3 minutes. Valve diaphragm partially stuck or inlet screen clogged
- Water fills continuously and overflows — valve stuck open. Samsung OE (overflow) error may display
- Leaking from underneath during fill — valve housing cracked or outlet connection failed
- Buzzing or hammering when fill starts — worn diaphragm vibrates under water pressure
Samsung dishwashers display error codes (HE, 5E, 4E, OE, LE) that narrow the diagnosis. Check the display before opening any panels.

Samsung Part Identification
OEM part number: DD62-00067A — Samsung uses the DA/DC/DD/DG/DE prefix system where the first two letters identify the appliance division (DA = refrigerator, DC = washer/dryer, DD = dishwasher, DG = range/oven, DE = microwave). Find your model number (DW series) on the rating plate behind the kickplate and verify the exact part at samsung.com/us/support/. Samsung frequently revises parts across production runs — always cross-reference with your specific model number rather than relying on a generic part number.
Where to find your model number: Open the door and check the rating plate on the inside edge of the door or on the tub side wall. Model numbers start with DW.
Cost Breakdown
| Component | Price |
|---|---|
| OEM part | $25-$75 |
| Aftermarket part | $15-$50 |
| Professional labor | $80-$160 |

| Total (professional) | $105-$235 |
Both OEM and aftermarket options are available. OEM ensures correct fit and Samsung diagnostic compatibility.
Safety First — Know the Risks
Appliances involve high voltage (120-240V), pressurized water, gas lines, and chemical refrigerants. Over 400 DIY repair injuries are reported yearly. Our techs are licensed and insured — let them handle the risk.

Step-by-Step Replacement
Turn off water supply and breaker. Remove kickplate. The valve is where the supply line connects.
- Turn off water supply shutoff valve and breaker.
- Remove kickplate. The valve is behind it where the water supply connects.
- Disconnect supply line with adjustable wrench. Have towel ready for residual water.
- Disconnect wire harness from the solenoid (2-pin).
- Disconnect internal fill hose from valve outlet (spring clamp).
- Remove valve mounting bracket screw (1-2 Phillips).
- Install new valve (DD62-00067A), reconnect outlet hose, harness, and supply line.
- Turn on water. Check every connection for leaks before restoring power. Run a cycle — tub should fill in 2-3 minutes.
Safety note: If you encounter unexpected resistance or signs of electrical damage (melting, burning), stop and call a professional.
Tools Required
- Adjustable wrench — for supply line compression fitting
- Phillips #2 screwdriver — for kickplate and valve bracket
- Pliers — for spring clamps on fill hose
- Towel — residual water when disconnecting
- Multimeter — test solenoid coil (200-500 ohms). OL = open coil
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

Samsung-Specific Tips and Common Mistakes
- Before replacing, check the inlet screen filter — a mesh screen where the supply connects to the valve. Mineral deposits clog this screen, mimicking valve failure. Clean with vinegar.
- Samsung dishwashers need 20-120 PSI water pressure. Low pressure causes buzzing, slow fill, and 4E errors. Test with a gauge before replacing the valve.
- Samsung dishwasher inlet valves have a single solenoid (unlike refrigerator dual valves). The valve is either open or closed — slow fill is a pressure or screen issue.
DIY or Professional?
This is a moderate repair. The valve is behind the kickplate with easy access. Plumbing connections and wire harness are the main work. Check every connection for leaks before finishing.
Consider calling a professional if:
- Supply fitting is corroded and cannot be disconnected
- 4E error persists after replacement — low pressure or kinked supply line
- Water continues to overfill — the board may not be sending the shutoff signal

What Happens If You Delay This Repair
A closed valve means no water and no washing. An open valve causes continuous fill — potential kitchen flooding. The OE overflow sensor shuts the unit down, but slow leaks may not trigger it immediately.
How Long Does a Samsung Dishwasher Water Inlet Valve Last?
A typical Samsung dishwasher water inlet valve lasts 7-10 years under normal residential use. Samsung's build quality and smart diagnostics help you catch declining performance before complete failure — set up SmartThings notifications if your model supports it.
Is It Worth Your Time?
The average DIY appliance repair takes 4-6 hours of research, troubleshooting, and parts ordering — with no guarantee of a correct diagnosis. Our technician diagnoses the issue in about 30 minutes — same-day appointments available.

Factors That Shorten Water Inlet Valve Life
- Water quality — hard water deposits calcium on the diaphragm
- Water pressure — above 120 PSI stresses the housing and seals
- Inlet screen neglect — clogged screen forces the solenoid to overwork
- Power cycling — rapid on/off wears the solenoid faster
Maintenance Tips to Extend Water Inlet Valve Life
- Clean inlet screen filter annually — unscrew supply line and remove the small mesh screen
- If buzzing gets louder over time, mineral buildup is worsening — clean screen and consider a water softener
- Shut off water supply if dishwasher will be unused for extended periods
The Risk of Getting It Wrong
A wrong diagnosis often turns a simple fix into a costly replacement. Without proper diagnostic tools, you might replace the wrong part — or cause additional damage. Our free diagnostic eliminates the guesswork.

FAQ
How much does it cost to replace a Samsung dishwasher water inlet valve?
OEM part costs $25-$75. Professional installation adds $80-$160, totaling $105-$235.
Can I replace the water inlet valve in my Samsung dishwasher myself?
The valve is behind the kickplate with easy access. Plumbing connections and wire harness are the main work. Check every connection for leaks before finishing.
How long does a Samsung dishwasher water inlet valve last?
Typical lifespan is 7-10 years under normal residential use. Regular maintenance and proper use are the biggest factors in reaching that lifespan. Samsung appliances with SmartThings can proactively alert you to declining component performance before complete failure occurs.
What Samsung part number do I need for my dishwasher water inlet valve?
The primary OEM number is DD62-00067A. Samsung uses the DA/DC/DD/DG/DE prefix system — the first two letters identify the appliance division. Always verify against your specific model number (DW series) at samsung.com/us/support/, as Samsung frequently revises parts across production runs. Using the wrong part can cause fit issues or void warranty coverage.
Is it worth repairing my Samsung dishwasher or should I replace it?
If your Samsung dishwasher is under 8 years old and the water inlet valve is the only issue, the repair at $105-$235 is typically worthwhile. If the unit is over 10-12 years old or has multiple failing components, compare the total repair cost against a new Samsung dishwasher and choose accordingly.
