Vorwerk Air in Pump / Cavitation

Pump is very loud or rattling, with pulsating spray output.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Low water level in tank, Air leak at tank outlet seal, Partially blocked inlet filter, Worn pump valves

Safety: Unplug before handling tanks.

Refill tank: Ensure the clean water tank is filled above the minimum level.
Check seals: Inspect and replace the tank outlet O-ring if it is not sealing properly.
Prime pump: Reinstall the tank, plug in, and hold the spray trigger continuously for 30–60 seconds to purge air.
Filter cleaning: Clean any inlet mesh filter between the tank and pump. If noise persists and flow is poor, the pump may be worn and should be replaced.
