Electronic check and action: • This indicates that the low level circuit is open i.e. the probe is not in contact with the water. • The element is switched OFF at this stage and the inlet is left ON. (note that if this is a low probe wiring fault, the water will stop at the high level probe regardless of the status of the low level). •
