Dyson PencilWash repair
Dyson PencilWash Charger or Adapter
Charger repair on the PencilWash covers only the charging supply, cable, power input, and dry battery contacts for its matching charger and charging connection. Pumping, washing, self-cleaning, and drying faults use the liquid-system or control-board path. This procedure is scoped to the PencilWash (WR04) and its dedicated Dyson wet-cleaner platform.

Instructions
How to diagnose this issue safely
- Bright flashlight
- Known-working wall outlet
- Clean dry lint-free cloth
- 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.
- Do not charge a swollen, cracked, leaking, wet, unusually hot, or impact-damaged battery.
- Do not open the charger, powered dock, battery cells, or charging electronics; keep every adapter and power input dry and never bridge charging contacts.
Confirm the PencilWash configuration
PencilWash (WR04) is ultra-slim dedicated hard-floor wet cleaner using one hydrated microfiber roller, a head-level waste tray, and no vacuum suction or exhaust filter. 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.
Identify the charging section of the dock or charger
Confirm the outlet works, then inspect only the external plug, adapter, cable, power input, indicator, and dry charging contacts of the matching charger and charging connection. A washing, pumping, self-cleaning, or drying failure is not a charger fault.
Clean and reseat dry connections
Unplug the matching charger and charging connection, empty nearby liquid components, and wipe only dry external charging contacts and seating surfaces. Do not put liquid or cleaning solution on a power contact, adapter, or dock input.
Read the documented indicator
Allow the machine and battery to reach normal room temperature. Record the exact light pattern, screen message, or app message and compare it with the exact owner guide; do not guess from another Dyson generation's indicator pattern.
Replace only confirmed charging hardware
If testing isolates the matching charger and charging connection's external supply, cable, input, or charging-contact function, replace only the complete charging part listed for PencilWash (WR04). Route liquid-flow failures to pump/liquid repair and electronic drying or cycle-control failures to control-board diagnosis.
