Supply block left complete SCHAERER Spare Parts 072802 1340052043

A supply left complete assembly controls the flow of water and steam into the brewing group and steam wand of a coffee machine. It acts as a central junction where incoming water is split, pressurised and directed to the boiler, the group head and the steam outlet. Without this assembly, the machine cannot deliver the correct volume or pressure to produce espresso or steam milk.

The sequence of use is fixed by the machine's programme. When the operator selects a drink, the machine's pump draws cold water from the reservoir or mains supply. The water passes through the supply left assembly, which routes it to the boiler for heating and to the brew group for extraction. For steam, the assembly diverts hot water from the boiler to the steam wand. The assembly's internal valves and seals ensure that water and steam travel only along the intended paths, preventing leaks or cross-contamination between circuits.

Construction is specific to SCHAERER coffee machines. The assembly is a single unit that replaces the original part without modification. It fits directly into the machine's existing mounting points and connects to the water inlet, boiler, brew group and steam wand with the original hoses and fittings.

Cleaning and upkeep follow from the materials and construction. The assembly should be removed and inspected whenever the machine is descaled or serviced. Any visible scale or debris should be flushed out with clean water; no disassembly is required. The seals and valves are not user-serviceable and should be replaced if they show signs of wear or leakage.

This is a spare part for SCHAERER coffee machines. It is listed in the manufacturer's catalogue under the spare parts section for water and steam management.
