Dyson V15s Detect Submarine repair
Dyson V15s Detect Submarine Pump or Liquid System
Pump and liquid-system repair on the V15s Detect Submarine follows the tank outlet, valve, delivery path, collection path, and sealed-pump boundary within the V15s Submarine wet roller head, clean-water reservoir, debris tray, and wet roller. Only the SV47 Submarine wet roller head collects liquid. Its tank, roller, and waste tray are maintained separately after wet use. The head is software-specific and is not compatible with a previously purchased dry V15. This procedure is scoped to the V15s Detect Submarine (SV47) and its V15s wet-and-dry cordless platform.

Order only a genuine replacement listed for V15s Detect Submarine (SV47) after the failed assembly is confirmed; family-name resemblance does not establish compatibility.
Instructions
How to complete this repair
- Bright flashlight
- Clean lint-free cloth
- Soft brush reserved for wet-head maintenance
- Container for captured water
- Power the vacuum off, remove its click-in battery, and detach the selected cleaner head before inspection.
- Use only owner-access points and maintenance actions documented for the exact machine code.
- Keep water away from the main vacuum body, battery, charger, robot electrical contacts, dock power connection, and powered dry cleaner heads.
- Do not use a wet head without every tank, tray, roller, cap, and seal installed in the documented orientation.
- Do not open a pump, valve block, liquid sensor, wet-head motor, robot body, or dock plumbing enclosure.
Confirm the V15s Detect Submarine configuration
V15s Detect Submarine (SV47) is a dry vacuum body with separate Digital Motorbar, Fluffy Optic, and Submarine wet-roller heads. Cataloged variants include V15s Detect Submarine. The verified owner-service profile identifies it as the Dyson V15s Detect Submarine wet-and-dry platform. Match the machine code and serial label before ordering a filter, bin, wand, dry cleaner head, wet-roller component, battery, or charger; a retail family name can cover incompatible hardware.
Separate the wet system from dry components
Remove the battery and detach the complete V15s Submarine wet roller head, clean-water reservoir, debris tray, and wet roller. Never pick up liquid through the dry cleaner head, wand-to-bin airflow path, or main cyclone body.
Empty and inspect each liquid container
Empty the documented clean- and dirty-water components after use. Check caps, valves, visible seals, latches, and tank walls for debris, a rolled seal, crack, blockage, or incomplete closure. Use only the water, fill level, and cleaning liquid expressly permitted by the SV47 owner guide; do not transfer V16 or robot instructions to this head.
Inspect the tank outlet and accessible liquid path
Follow the exact owner method to inspect the clean-water outlet, cap, valve, visible seals, head inlet, collection edge, and accessible channels. Do not push tools into tubing or open a pump, valve block, or liquid sensor.
Inspect the platform-specific liquid path
Check the V15s head inlet, reservoir outlet, extraction edge, debris tray, and tank seating. A leak from the head-body seam or failure to dispense after these checks requires complete-head service.
Make one controlled liquid-delivery test
Refit every component, add only the documented amount of clean water or approved solution, and test briefly on a suitable hard floor while watching the exact dispense and recovery points. Stop for a leak, pump error, abnormal noise, or failure to move liquid.
An internal leak, pump fault, valve fault, sensor error, or powered-roller fault requires professional service or a confirmed complete external assembly. A dock-contained failure uses robot-dock repair.
