Hot Tub FLO Error: Don't Panic! Here's How to Fix It

[@gabriellefrance1452]

I need some assistance. I have a 2013 masterspa healthy living 8 that we have replaced the old pac MS35U to master-spa x300732 MS50U control pack, have two 1 HP Pumps that run our jets and a circulation pump that we replaced thinking it wasn't working because it was giving us a 'Heater may be dry error' and then 'heat sensor imbalance' errors. Tried to match up the dip switches and into test mode to program the spa pac to draining and putting power washer through the lines to make sure there isn't a clog...refilled to get same error again...now sure where to turn now....

ok, this sounds like it is not configured correclty for th part you have plugged in. You get a flow error if the spa pack thinks it has turned on the circulation pump but it actually hasnt. MS 50U is basically a BP501 spa pack. Circulation pump should be in J21, Jet Pump should be in J8 & J14. You need to select a setup mode that reflects this - the OEM BP501 this would be mode #2 - I have a video that explains this here - kzbin.info/www/bejne/b2Wbno2ZibKch9U if the pack is set to default, it will expect a dual speed pump rather than a circulation pump and this is why you are getting the error - hope that helps - Andi

@Buildahottub I have those in the correct spots. Can try to put set up #2 in the test mode area. Only thing I question is where the white jumpers should be, in area 3, which is where I have them and moved J47 from area 1 to area 3 thinking it may be the issue since it says the circ. Pump 1 and Ozone all need to be same voltage, 240 not 120. Or could my heat sensor be faulty that is plugged into J29... which dip switches should be up? 3?
