ECM and Profitec Coffee Machine Anti-Vacuum Valve – Stainless Steel Version

ECM and Profitec Coffee Machine Anti-Vacuum Valve – Stainless Steel Version

Replace a faulty or leaking boiler anti-vacuum valve on your ECM or Profitec espresso machine with this genuine OEM stainless steel replacement. This anti-vacuum valve (also called a vacuum breaker) sits on the boiler and opens automatically when the machine is switched off and the boiler cools, preventing a vacuum forming inside the boiler and allowing it to drain safely. The stainless steel body offers improved corrosion resistance over the standard brass version.

Stainless Steel vs Brass – Which Should I Choose?

Both the stainless steel and brass anti-vacuum valves are genuine OEM parts compatible with the same machines. The stainless steel version offers better resistance to corrosion and scale build-up, making it a preferred choice for machines used with harder water or in areas with high mineral content water.

Frequently Asked Questions

What does the anti-vacuum valve do?

The anti-vacuum valve (vacuum breaker) sits on the boiler and opens when the machine cools after being switched off. This prevents a vacuum forming inside the boiler that could pull contaminated water back in or damage internal components. A small drip of water from the drain line after switch-off is normal operation.

Is the drip of water after switch-off normal?

Yes — a small drip from the boiler drain line after switching off is normal and indicates the anti-vacuum valve is working correctly. If the valve drips continuously during machine operation or leaks from the body, it requires replacement.
