Why is steam escaping from the cap of the tank?

Question

Accepted Answer

If steam is escaping from the cap of your EUROFLEX Vapour M4S, there may be several causes:

Worn or damaged seal - The sealing gasket of the cap can deteriorate over time. According to the product documentation, the gaskets are replaceable. Inspect the gasket to check for cracks, hardening, or wear.
Cap not tightened properly - The cap must be screwed on tightly to create a pressure seal. Make sure to tighten it properly by applying even pressure.
Pressure relief valve - The device operates at 3.5 bar and is equipped with a safety valve. A slight release of steam from the cap during heating is normal as a safety mechanism.
Too much accumulated pressure - If steam is continuously escaping, the pressure relief valve may be functioning to protect the device.

Allow the device to cool completely before any intervention.
Check that the cap is fully screwed on with even pressure.
Inspect the condition of the sealing gasket around the cap.
If the gasket is damaged, contact an authorized EUROFLEX service center to obtain a replacement kit.
Clean the threads of the cap and tank to ensure that no residue is obstructing the seal.
