In many automatic machines, supply pressure brings water in, and a pump drains it out. The valve controls intake; the drain pump serves a different function.
Inlet and outlet diagram
- The faucet and hose carry water to the unit.
- The inlet screen traps particles of the size it was designed for.
- The solenoid valve opens the passage when it receives the intended command.
- The water can pass through the dispenser or follow another documented route to the tub.
- After use, the lines carry the bath out through the outlet, with a pump when the design includes one.
- The hose discharges into the site’s drain connection.
This diagram describes functions, not disassembly positions. A distributor can select different compartments or nozzles depending on the phase.
Variants that change the flow path
With a dual inlet, the control can combine cold and hot water. In recirculation, one branch returns part of the bath to the load. In a gravity-fed semi-automatic, opening the outlet mechanism allows drainage to a point located as indicated in its manual, without inferring heights from a pump-based system.
The level sensor informs the control of a hydraulic condition; it is not the part that brings water in. A flow meter, when present, measures water flow and serves another function.
From the diagram to the actual connections
The inlet joints must withstand supply conditions. The outlet installation must allow drainage without backflow or siphoning. Their requirements are not interchangeable, even if both use hoses.
Identify the supply, intake, tub, and drain before interpreting which circuit a connection or component belongs to.
