Why is the fault indication lamp lighted in red on my amiad EBS-10000 Water Filtration Systems?

If your amiad Water Filtration Systems filter is experiencing a continuous signal from the pressure differential switch for more than 15 minutes, indicated by a red fault light, it could be due to a clogged filter from heavy dirt or high water flow. Try closing the downstream valve, then press the reset button. Perform a few manual flush cycles, watching the PD signal. Once clean, gradually reopen the downstream valve, checking the PD and flow rate to ensure it stays within the filter's limits. Another cause could be a faulty PD switch, in which case you should ask a qualified electrician to check the connections and operation, and replace the switch if needed.
