Siemens EQ 5 Macchiatto Plus - does not pass water through coffee nozzles

The most likely fault is the valve that routes water to the brewing unit—usually the brewing solenoid/three-way valve or its lower seat gasket—so water goes to the drip tray or frother instead of the coffee spouts, and the brewer itself may still be OK [#17549500] [#17629286] [#17757640] If water comes from the frother, the pump is working, which points to the electro-valve for the brewer being clogged or damaged [#18472127] To narrow it down, remove the brewing block, flush it with warm water, and do a syringe test; if the block passes water, then check the pump valve, the inlet connector to the block, and the inside of the machine for leaks [#17755723] One repair reported on this EQ.5 was replacing the gaskets in the black internal part where the block connections enter, accessed by removing the left side cover near the water tank [#17961300] In the original case, the brewer was not damaged; the machine needed service because it had lost an important valve, likely the three-way valve [#17549500]
