Insufficient hot water is indeed a strong indication of a faulty hot water heater element. The heating elements in an electric hot water heater are responsible for heating the water to the desired temperature. If one or both of these elements fail, there may not be enough heat produced to warm the water adequately, which can result in lukewarm or cold water being supplied to fixtures. This situation can lead to dissatisfaction with the hot water supply, especially during peak usage times.

In contrast, a constant supply of hot water often suggests that the heating elements are functioning properly, as they effectively maintain the water temperature. Water leaks may indicate plumbing issues but are not directly related to the performance of the heating element itself. High water pressure could cause other types of concerns but does not directly signal element failure either. Therefore, the presence of insufficient hot water strongly suggests a malfunction within the heating elements of the water heater.
