Flowmeter hose for Siemens EQ.500 coffee machines

What is the flow meter hose

The flow meter hose connects the pump and the water flow sensor in the coffee machine's circuit. All the water dosed during preparation into the coffee or into the hot water and steam system passes through it. The flow meter controls precise dosing based on the amount of water that has flowed through, so the connection must be watertight and unobstructed.

How to spot wear

As the material ages, the hose loses flexibility, can crack or come loose from the couplings. Typical symptoms include dripping or leaking water inside the machine, inaccurate amount of coffee or water in the cup, error messages related to flow, or a complete stop of brewing. Sometimes the pump also becomes noisier as it draws in air through a leaky spot.

When it's time for a replacement

A leaking hose can allow water to get into the electronics or damage surrounding parts, so it's not worth waiting for it to burst completely. Replacing the hose usually restores correct dosing and eliminates error messages related to the flow meter.

How to choose the right hose

Hoses differ in length and the way they connect depending on the specific coffee machine model, so please check compatibility in the product table before purchasing.
