Hi Dom, The "LO" error code can be cause by several different things as reference in the Hayward H-Series Owner's Manual, with the faulty pressure being one of them.

Hi, Brad. They're different models of the H250 Heater, this Pressure Switch - FDXLWPS1930 will work with the H250FDP or H250FDN models.

I keep getting an error code of LO on my Haywood 400FD pool heater display. The filter is clean and the heater is receiving 100% water flow-through. How can I check to see if the water pressure switch is defective? Is Water Pressure Switch (fdxlwps1930) the correct replacement part?

Hi, JJ. The "LO" error code could be cause by a faulty Water Pressure Switch, Vent Pressure Switch, or Temperature Limit Switch. Use the Universal H Series Heaters Troubleshooting Guide to diagnose the cause.
