Dometic MasterFlush Toilet Flush Switch Panel | 313409010 | Gray

Control your Dometic MasterFlush electronic macerator marine or RV toilet with the Dometic Sealand 313409010 DFS/GRY Flush Switch Panel. This flush-mount switch panel features a user-friendly interface for one-touch flushing — plus integrated indicator lights that show tank level and power status at a glance. The right replacement when your existing flush switch has failed, been damaged, or needs upgrading to match an updated bathroom aesthetic.

What This Switch Does

The DFS/GRY flush switch is the user-facing control for MasterFlush macerator toilets:

• One-touch flush activation — clean, residential-style flush control
• Tank level indicator lights — visual warning when the holding tank approaches capacity
• Power indicator lights — confirms the toilet system has power and is ready to flush
• User-friendly interface designed for intuitive operation

Unlike basic foot-pedal flush mechanisms, the DFS switch gives you wall-mounted electronic control with the added benefit of system feedback — you know at a glance whether power is good and whether your holding tank has capacity for another flush.

For Dometic MasterFlush Macerator Toilets

The 313409010 is designed for use with the Dometic Sealand MasterFlush electronic macerator toilet line. MasterFlush toilets use an electric macerator pump to break down and pump waste — different architecture from gravity, vacuum (VacuFlush), or basic electric toilets. Verify your existing toilet is a MasterFlush model before ordering.

Dual-Voltage 12/24V Operation

The 313409010 supports both 12V and 24V DC electrical systems:

• 12V DC — standard RV electrical compatibility
• 24V DC — common marine electrical compatibility
• Dual-voltage flexibility — same switch works across both common installation types without separate variants

Gray Finish — Color Variant Available

This is the gray (DFS/GRY) variant of the MasterFlush flush switch panel. Dometic also offers a white (DFS/WHT) variant under part number 313409020 — same function and dual-voltage operation, just white finish to match lighter bathroom palettes. Pick the color that matches your existing bathroom aesthetic.

Includes 6 ft Ethernet Cable

The 313409010 ships with a 6-foot Ethernet cable for connecting the switch panel to your MasterFlush toilet's control system. The included cable typically provides adequate length for most installations — if your bathroom layout requires longer routing, a longer Ethernet cable can be substituted.

When to Replace the Flush Switch

Common reasons to replace the DFS flush switch:

• Switch is unresponsive when pressed — no flush activation
• Indicator lights don't function — no tank level or power status feedback
• Intermittent operation — works sometimes, doesn't other times
• Visible damage — cracks, broken interface, or worn appearance
• Updating bathroom aesthetic — switching from white to gray to match new decor (or vice versa)
• Replacing damaged unit from impact, moisture, or wear

Before assuming the switch has failed, rule out simpler issues — Ethernet cable connection, wiring continuity, power supply, control board — since these can mimic switch failure symptoms.

Flush-Mount Installation

The 313409010 is designed for flush-mount installation — sitting flat against the bathroom wall rather than protruding. Clean, finished appearance for residential-style RV and marine bathroom installations.

Dimensions for Fitment Verification

• Width: 3.42" (89 mm)
• Height: 3" (76 mm)

Verify your existing switch cutout matches before ordering — the 313409010 is a direct replacement for the standard DFS switch cutout.

⚠️ Professional Installation Recommended

Electronic toilet control component replacement involves working with the toilet's electronic control wiring and Ethernet connections. Installation should be performed by a qualified RV or marine service technician for proper connection and operational verification.
