Samsung Dishwasher Water Inlet Valve Parts — Models & Compatibility

If your Samsung dishwasher won't fill with water, makes a humming noise during the fill cycle, or displays a water supply error code, the water inlet valve is usually the culprit. This hub covers the DD62-00084A replacement valve that fits over 20 Samsung dishwasher models across the DMT and DW series. This OEM-compatible part replaces Samsung part numbers AP5178218, PS4222448, 2692215, and EAP4222448.

Is This the Right Part for Your Model?

The DD62-00084A water inlet valve fits Samsung dishwashers manufactured between 2010 and 2018, including the DMT400, DMT610, DMT800, and DW series. To verify compatibility, locate your model number on the door edge or inside the door frame — it'll look something like "DMT800RHS/XAA" or "DW80F600UTB/AA-00". Cross-reference your complete model number (including the suffix after the slash) with the compatibility list below, since valve configurations can vary even within the same series.

About This Replacement Part

The water inlet valve controls water flow into your dishwasher's tub during the fill cycle. It's an electrically-operated solenoid valve that opens when the control board sends power during wash and rinse cycles. When this valve fails, you'll typically see one of three scenarios: no water entering the tub at all, water trickling in slowly (taking 10+ minutes to fill), or water continuing to flow even when the dishwasher is off. The valve sits at the bottom left or right of the dishwasher where the water supply line connects, and it's held in place with a mounting bracket and hose clamps. This replacement includes the complete valve assembly with the solenoid coils already attached — you don't need to transfer any components from your old valve.

What You'll Need for Installation

Replacing a dishwasher water inlet valve is straightforward if you've got basic hand tools. You'll need a 1/4" nut driver or socket for the mounting screws, adjustable pliers for the water supply line connection, and a shallow pan or towels to catch residual water. Plan on 30-45 minutes for the job. The most important step is turning off the water supply valve under your sink and disconnecting power at the breaker before you start — don't just use the dishwasher's door switch, because the valve can still be energized even when the door is open.

Why Water Inlet Valves Fail

These valves typically fail because of mineral buildup from hard water, which prevents the solenoid plunger from moving freely. If you've got hard water, you'll see white calcium deposits around the valve inlet screens — those deposits eventually restrict the valve's opening enough that it can't supply adequate pressure. The solenoid coils can also burn out if they're energized for extended periods, which happens when the control board malfunctions or if the valve gets stuck partially open. Some valves develop internal leaks where water seeps past the rubber diaphragm, causing water to enter the tub even when the dishwasher is powered off.
