Documented faults
- Numatic GVE370
George is part-way through a wet pickup and suddenly stops drawing up water — the motor note changes pitch, and running the hose over wet ground or carpet does nothing more
Numatic's own troubleshooting table names this directly: the float valve has operated, which is the machine's own detection that the recovery tank is full (or reads as full) and is cutting off suction before water can reach the motor — not a blockage or a failed motor

Henry vacuum suddenly cuts out mid-clean and won't switch back on, even though it was working normally moments before
The motor's thermal overload cutout has tripped because of restricted airflow — a safety feature, not a failed motor — and it won't reset until the blockage is cleared and the motor cools down
