The pentair mini-max only displays LO when the water temperature is at or below 58 degrees F.
The heater is set to not fire at this temperature due to the condensation that can occur.
If the water is above this temperature and you are still getting this code, the temp sensor is installed incorrectly or is just bad.

Mini max my power light comes on but my pressure sw does not light up


Try cleaning the filter, or check the water flow. It's sensing not enough water flow through your system.

What does error code r =8 at startup mean? Turned heater on for first time this year. Opened gas valve at tank and shut-off at heater. Pump is running. Turned 220 v breaker on in box and "spa on"...


Mike, I have found what I believe is the correct manual for your heater at http://www.pool-heaters.com/pdf/Pentair-Maxetherm_manual.pdf. I couldn't find an error code list in the manual but I might have missed it. If you call the the StaRite technical support line at 888-782-7483 they should be able to help youfigure this issue out. I hope this helps.

Please vote on this answer. Thank you.

Air Flow Fault, E04 and E05 Errors, all are ingniter related?


Is it the digital user interface? Often when you are receiving multiple error codes, its the control board that is bad. This is not as common in Mini-maxes and it's an expensive fix but it might be what's wrong. Most heater problems, however, don't have anything to do with the heater. Make sure your flow is good. Clean all baskets (skimmer and pump) and backwash (D.E. or Sand filters) or clean (cartridge filter) your filter.

Digital display shows LO what should i do


LO is a limit string open. This is what I refer to as a saftey circut. It will peobally be a dirty filter or a plugged up basket. The heater need enough water flow to run or it will overheat and cause damage to the heater. Without enough flow the saftey circut shuts the heater down before this can occur. If it is more than this it is probally time to get a repairman involved. Good luck and remember this is a box full of fire that runs on high voltage.
