Abstract

A device for testing a solenoid valve (2) comprises a solenoid valve (2); a voltage generator (8) for applying a short pulse of voltage, which is not long enough to open the solenoid valve (2), to the windings (6) of the solenoid valve (2); a current meter (10, 12) configured for measuring the current flowing through the windings (6) of the solenoid valve (2); and an analysis device (16), which is configured for analysing the current measured by the current meter (10, 12) for detecting a potential fault of the solenoid valve (2).
