1. A method for monitoring a bathing system, the bathing system including a set of bathing unit components, the set of bathing unit components including at least two bathing unit components configured for acquiring an actuated state and a non-actuated state, in the actuated state the bathing unit components drawing an electrical current, said method comprising:

  • a. providing a memory unit for storing information related to electrical currents drawn by the bathing system under normal operating conditions, at least a portion of said information conveying measurements of electrical currents drawn by respective bathing unit components when in the actuated state;

    b. using a processing module, deriving at least one expected current measurement at least in part by processing;

    i. the information related to electrical currents drawn by the bathing system under normal operating conditions stored on the memory unit; and

    ii. desired state information associated with the bathing unit components in said set of bathing unit components, the desired state information conveying which of the actuated state and the non-actuated state bathing unit components in said set of bathing unit components are to acquire;

    c. obtaining an observed measurement of a current drawn by the bathing system;

    d. using the processing module, determining if the bathing system is experiencing an abnormal operational condition at least in part by processing the at least one expected current measurement and the observed measurement of the current drawn by the bathing system.
