Dometic Traveler 510+ RV Toilet Exploded Parts Diagram & Repair Guide

The Dometic/SeaLand Traveler 510+ has a ceramic bowl, a foot-operated flush-ball mechanism and a removable pedestal assembly. When the toilet leaks at the flush opening, the pedal mechanism sticks or the bowl-to-base joint needs service, the original numbered parts drawing helps identify which component to replace. This guide covers the Traveler 510+ tall model, including white item 302651001 and bone item 302651003.

Dometic Traveler 510+ exploded parts drawing

Dometic's sanitation replacement-parts guide contains the actual illustrated 510+ assembly, with callouts for the seat, vacuum breaker, bowl, clamp, flush-ball seal, base, pedal, water valve and floor seal. In the manufacturer's 2024 guide, look for “PARTS LIST: 510+ MODEL” on page 140 of the parts-list section. On a phone, the direct PDF link is usually easier to zoom than an embedded viewer.

Numbered Dometic Traveler 510+ parts reference

Reference numbers below match the current 510+ manufacturer drawing. Linked numbers open the corresponding part on NewRVParts.

An asterisk denotes optional hand-spray components on the manufacturer's drawing. The water valve, ceramic bowl, optional spray and other components are included as reference numbers even when a matching part is not linked in this guide.

Choosing the right repair component

1. Flush opening does not seal: Dometic lists 385311462 as the replacement flush-ball seal set. Check the condition of the ball and shaft assembly before deciding whether the seal alone will resolve the problem.
2. Pedal or flush linkage is damaged: 385310578 is a pedal/lever and cartridge kit, while 385236096 supplies a spring cartridge alone. The white exterior pedal cover is a different part, 385310114.
3. Bowl-to-base joint needs service: Match the bowl/base clamp 385310048 and associated sealing components to the parts shown in the exploded drawing. The clamp is not itself a rubber seal.
4. Leak at the floor connection: Dometic identifies 385310063 as the floor/base seal. Check the floor flange and mounting hardware for damage before reassembling the toilet.
5. Water-supply vacuum breaker: 385316906 is the standard no-hand-spray version. Toilets equipped with the optional hand sprayer use a different vacuum-breaker arrangement.
6. Toilet seat replacement: Match the original colour and bowl style: 385343829 is white, and 385343831 is bone. Both are seat-and-lid assemblies, not replacement ceramic bowls.

Before working on water-supply components, close the water source, release pressure and inspect the existing assembly. Follow Dometic's service instructions for removing the ceramic bowl and flush mechanism.
