Can a coffee machine explode?

Yes, coffee machines can explode if the internal valves become overly pressurized with air supplied to the steam boiler. The broiler will accumulate steam and air pressure.

If the pressure is allowed to keep building without relief from the steam relief valve, frother, or spout, it will pressurize with air that cannot escape. It will continue to build until the structures of the machine give way and explode. This occurrence is relatively rare. However, several news reports detail this issue over the past decade from multiple news sources around the globe.

Preventing an exploding coffee machine is not foolproof or guaranteed. Keeping the machine clean and practicing regular maintenance, and replacing broken parts immediately will significantly reduce the chance of explosion.
