What would be a common sign of a malfunctioning steam trap?

A common sign of a malfunctioning steam trap is constant steam release. Steam traps are designed to allow steam to pass through while preventing the passage of condensate and non-condensable gases. When a steam trap is functioning properly, it will release steam intermittently, allowing for effective heat exchange and preventing excessive steam loss. If there is a constant release of steam, it indicates that the trap may be stuck open or not sealing properly, leading to inefficiency in the system and potential energy loss. This situation can also result in increased operating costs and reduced temperature control in cooking equipment.

In contrast, while inconsistent cooking times could suggest other issues with the equipment, and a sizzling noise within the kettle might indicate that water is heating rapidly, neither directly points to the specific malfunction of a steam trap like constant steam release does. Excessive oil on the surface is unrelated to the function of steam traps and would typically indicate a different issue, such as problems with product preparation or maintenance.
