My Essence Echo Spa jacuzzi is giving us an error "FL". Can you tell us why it is saying this and how we can fix it? Thanks!

do a local google search online for a motor shop in your area.
sounds like the jacuzzi pump is bad. maybe a bad winding or bad bearing.

2X2 AND A HAMMER, THE RIBS GIVE YOU JUST ENOUGH SPACE TO TAKE THE WOOD EDGE AND SMACK IT, GO FROM ONE SIDE TO THE OTHER, ONE OR TWO HITS EACH TIME.
IT WILL GIVE IN AND LOOSEN .. USE MAGIK LUBE NEXT TIME ON THE THREADS AND O-RING AND YOU WILL NOT HAVE THIS ISSUE AGAIN..

Is it bad to run it like that ? I've cleaned everything out and reset it and it still comes on?

Its possible your heater has a ground fault. If the old pressure sw was giving the FL code the system would not send power to the heater. Now with the new sw working power is being sent to the heater.

FL is a flow error, you may not have enough water going over filter housing. Jets are they open?
is your heater fitted with a pressure switch? when on FL locate pressure switch wheel and turn all the way anti clockwise until it stops then slowly wind back until you hear a click reset in control box - you have reset pressure switch.
If you have done this and still show FL or heater is not fitted with pressure switch then your LOW speed on pump maybe faulty (new pump) or heater maybe scaled up with lime scale and reducing water flow through heater - remove scale from heater, flush through and increase ANTI-SCALE

the FL code is usually an insufficient flow fault. you may have a dirty filter or a faulty flow switch/sensor.
