Samsung Dishwasher Leak Sensor Assembly Parts — Models & Compatibility

If your Samsung dishwasher is displaying an error code or refusing to start because it thinks there's a leak, the DD94-01062A leak sensor assembly is what you need. This OE-quality replacement part monitors water in the base pan and signals the control board to shut down if it detects moisture — a critical safety feature that prevents water damage to your kitchen floor.

Is This the Right Part for Your Model?

This leak sensor fits over 50 Samsung dishwasher models from the DMT, DW79, and DW80 series. Your model number is typically located on the inside edge of the door frame or on the tub sidewall when you open the door. Look for a white or silver sticker with a string of letters and numbers starting with "DMT" or "DW." Cross-reference that number with the compatibility list below to confirm fitment.

About This Replacement Part

The DD94-01062A leak sensor assembly sits in the bottom of your dishwasher's base pan and includes the float switch, mounting bracket, and wiring harness. When water leaks into the base, the float rises and triggers the sensor, which tells the control board to stop the cycle and display an error code. Samsung designed this as a fail-safe to protect against catastrophic water damage from hose failures, door seal leaks, or pump malfunctions. This replacement part supersedes older part numbers AP5325136, PS4222735, and 3188351, so if you're looking for any of those numbers, this is the updated version you need.

Compatible Samsung Dishwasher Models

This leak sensor assembly works with the following Samsung dishwasher series and models. If your model isn't listed here, check the full compatibility chart on the product page or contact our parts team for confirmation:

• DMT Series: DMT350RFS, DMT400RHB, DMT400RHS, DMT400RHW, DMT610RHB, DMT610RHS, DMT610RHW, DMT800RHB, DMT800RHS, DMT800RHW
• DW79 Series: DW7933LRABB, DW7933LRASR, DW7933LRAWW
• DW80 Series: DW80F600UTB, DW80F600UTS, and related models

These models span Samsung's mid-range to premium dishwasher lines from approximately 2010-2016. The sensor design remained consistent across these series, so one part number covers dozens of machines.

When You'll Need This Part

Most people discover they need a new leak sensor when their dishwasher won't start and displays an LE, LC, or E7 error code — all of which indicate a leak detection issue. Sometimes the sensor itself hasn't failed, but corrosion on the contacts or debris in the base pan causes a false positive. Other times, the float mechanism sticks in the "up" position even after you've dried out the base. If you've already confirmed there's no actual water leak and cleaned the base pan, but the error persists, the sensor assembly needs replacement.

Installation Overview

Replacing the leak sensor requires accessing the bottom of the dishwasher. You'll need to disconnect power, remove the lower access panel or tip the unit on its back, and locate the sensor in the base pan. The old sensor unplugs from the wiring harness and typically mounts with one or two screws. The new assembly plugs in the same way — no splicing required. If you've worked on appliances before, this is a straightforward 20-30 minute repair once you have access to the base.
