Dyson WashG1 repair
Dyson WashG1 Control Board Repair
A control-board repair on the WashG1 begins only after its exact power source, physical controls, connectors, sensors, and driven loads are separated from a confirmed electronic-controller fault. This procedure is scoped to the WashG1 (WR01) and its dedicated Dyson wet-cleaner platform.

Instructions
Safe checks before professional service
- Bright flashlight
- 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 open a battery pack, mains adapter, sealed main body, robot, wet-cleaner control housing, motor controller, or PCB enclosure.
- Stop for liquid exposure, swelling, melting, electrical odor, sparks, smoke, repeated high-current errors, or a hot connector.
- Do not open the motor, battery pack, charger, switch, wiring, control board, pump, sensor module, or another sealed electrical assembly. Internal diagnosis belongs with a qualified repair technician.
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.
Preserve the exact electronic symptom
Record every WashG1 screen, app, spoken, light-pattern, or operating error before resetting anything. Note which command fails and whether the problem follows charging, startup, liquid flow, roller operation, or a specific powered assembly.
Rule out the external power and physical control
Confirm the correct self-clean dock and charging contacts, complete wet-cleaner battery assembly specified for this model, physical switch or button, and dry owner-accessible contacts are intact. A failed battery, charger, cord, dock, or actuator must not be mislabeled as a board fault.
Separate the controller from its inputs and loads
A technician should test the model-specific connectors, sensors, two counter-rotating microfiber rollers and debris brush bars, motor or drive loads, and charging path before condemning the PCB. A shorted motor, wet connector, jammed drive, or failed sensor can create the same controller error and damage a replacement board.
Use the exact matched electronic assembly
If diagnosis confirms the controller, replace only the WashG1 (WR01) board, display, controller, or complete body assembly specified for that hardware revision. Complete any required calibration or pairing, verify insulation and connector routing, then test each affected function under controlled conditions.
