What does FLO mean on display on hot tub - Pool & Spa

Water flow error on hot tub means low water flow. This is not enough water flow to turn the system on.
Some motors do have a start capacitor on them. you can certainly check that or take it to your local motor repair shop and they can check that for you.

THIS SHOULD MEAN THAT THE CIRCULATION PUMP IS OPERATING, IF IT IS NOT THERE IS A PROBLEM WITH THE CIRCULATION PUMP. LOOK FOR YOUR LOCAL POOL PUMP MOTOR REPAIR SHOP WITH FREE TESTING..

I responded to the previous question in regards to the motor only. The xp2 does not have the strainer basket that the max-e-pro has . If this was a regular hot tub, the xp2 would work great, if this is above ground, then you do need a pump with a strainer basket. Again the xp2 will not work for an inground hot tub as the set up is different than an above ground unit.

The problem is that the flow switch for your water heater is indicating no flow. Therefore your water heater will not operate. Without proper water flow your heater will burn up. Check that your valves are open. Check that your pump is running. Check that your filters are properly installed and not restricting flow. Check the wiring to your flow switch and make sure the flow switch operating properly (i.e. put a ohm meter across the contacts and see if you have continuity when the switch closes).

"flo" means there is none ... flow that is. You may have a damaged impeller.

The fault is most likely to be the condensor. They can and do fail at an early age.

You don't need to dismantle the pump, on the rear of the pump you'll find a slot on the motor shaft which can be turned with a screwdriver.

If you've only just reffiled the hot tub it could also be an airlock.

FLO is related to either a dirty filter or a clogged suction to the pump or possibly a pump related fault. FIL2 is the code displayed when programming the 2nd Filtration Cycle.

Ken,

You need to contact a hot tub technician/engineer as you clearly have issues.

'ICE' means that the water temperature is too low and therefore the pumps will be turned on to prevent freezing within the plumbing. Depending upon the spec and settings, the heater maybe disabled during 'ICE' condition.

'ECON' is Economy Mode. If you have a mode button, keep pressing it until you see 'Stan' on the display. This will put the system back into the standard mode.

'FLO' means that there's insufficient flow of water through the heater, or non at all. 1) Check the water level - top up if low. 2) Ensure that all jets are open and flow water - if they don't you may have a pump issue. 3) Remove the filter(s) and see whether or not this clears the fault, if so clean or replace the filters.

'COOL' is displaying because the set temperature is much higher than the current water temperature.


As I mentioned at the start, you really should get someone to take a look at your hot tub. You may have a few issues that need resolving.
