Dyson WashG1 repair
Dyson WashG1 Pump or Liquid System
Pump and liquid-system repair on the WashG1 follows the tank outlet, valve, delivery path, collection path, and sealed-pump boundary within the WashG1 roller system, clean- and dirty-water components, debris or waste tray, and dock where fitted. This procedure is scoped to the WashG1 (WR01) and its dedicated Dyson wet-cleaner platform.

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 wet cleaner off, disconnect its charger or dock from the outlet, and empty its clean- and dirty-water components 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 WashG1 configuration
WashG1 (WR01) is dedicated hard-floor wet cleaner using counter-rotating motorized rollers instead of vacuum suction, with separate debris, clean-water, and dirty-water systems. Match the machine code and serial label before ordering a wet roller, tank, waste or debris tray, external seal, dock component, battery, or charger; a retail family name can cover incompatible hardware.
Separate the wet system from dry components
Power the WashG1 off, disconnect its charger or dock, and remove the documented tanks, tray, and roller cassette. This machine uses rollers and water collection rather than a vacuum suction airway.
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, approved solution, tank, and fill level specified by the WashG1 owner guide; do not transfer another wet cleaner's chemical or tank instructions.
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 WashG1 tanks, roller chamber, extraction edge, waste or debris tray, and dock channels where fitted. Run only the documented self-clean cycle after every external electrical surface is dry and the machine is fully assembled.
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.
