LF Error Code on Balboa VS510Z Spa Pack

Q: I have a hot tub with a Balboa 510Z  it is coding LF what does that mean.  It went from 104 degrees and now is maintaining only 59 degrees.

A: LF - Means persistent low flow problems, spa has had five High limit events in the last 24 hours.

 The simplest cause of this is a very dirty filter cartridge.  I would pull it out and clean it or replace it if it more than a couple of years old.

 On the VS this could also mean a problem with one of the temperature sensors but this is less likely.

 If you do need a filter you should be able to find it at the link below:

Replacing Hayward SP1580 Power Flo LX Spa Pump

Q: I am looking for a SP1580Z2 1 1/2 H.P. Power-Flo LX Pump for my hot tub, any help?

A: They do not make the complete SP1580Z2 any longer. We can get parts to rebuild or repair them but we cannot get them assembled. If you would like to pursue rebuilding it let me know.

If you want to replace it we use the Aqua-Flo FMHP and 2 Hayward adaptors to make the plumbing line up.  You can find it at the link below:

You will want the 1.5 Horsepower to match yours and it comes in 115 volt or 220 volt check your motor label.

You will also need two adaptors to make the transition easy (order the orings as well):
