A low cost method and system for diagnosing and reporting potential pump system failure. A method embodying the invention includes calculating amperage variables for the pump moter using a signal from an amp sensor measuring electrical current used by the pump. Design values for the pump are acquired and diagnostic values are calculated using one or more calculated amperage variables and one or more of the acquired design values. Using the diagnostic values, diagnostic parameters are then calculated. Each design parameter is then compared with a baseline value or pattern. Where the design parameter verifies beyond a set tolerence limit, an adverse diagnosis is reported.
