Temperature Not Displayed

Spa/Swim Spa may be in Economy or Sleep Mode. To see the temperature displayed, switch Spa/Swim Spa to Standard/Ready mode, or run pumps for 1-2 minutes.

- -°F   or - -°C

Water Temperature Unkown

After the pump has been running for 1-2 minutes, the temperature will be displayed.

HFL

Temperature Sensors out of Sync. Low Flow

Ensure water level is correct, fill spa up if necessary. Double check pumps were purged and primed. If an error persists, call your dealer or service organization.

FLO

The system has detected no water flow during the heater pump operation (Pump 1 or Circ pump).

Check for proper water level in spa. Check bottom suctions screens for blockage and clean filters. Check that heater and heater pump plumbing valves are open (in spa equipment area, if equipped). Turn spa off and then back on. Check if the heater pump (Pump 1 or Circ.) is operational and, if so, make sure it is not air locked. If an error persists, call your dealer or service organization.

OH or OHH or OHS

Overheat: The spa has shut down. The spa temperature has reached 108/42°C.

DO NOT ENTER SPA WATER! In warmer climates, equipment constantly running can cause water temperature to increase, also known as “heat creep”. Review and reduce filter cycle duration timing (default to 4 hours per day). Remove or prop open spa cover to allow water to cool (never leave spa cover open and unattended). Or, add cold water, but do not overfill the spa. Measure water temperature with digital thermometer. If the spa water temperature reaches a couple degrees or more below 108°F (42°C), turn power off to spa and then back on. If an error persists and the water temperature is below 108°F (42°C), call your Master Spas dealer or service organization.

HL

Heater Flow Loss: The water temperature in the water heater has reached 119°F/48°C.

DO NOT ENTER SPA WATER! Measure water temperature with a digital thermometer for safe temperature before proceeding. Check for proper water level in spa. Check bottom suctions screens for blockage and clean filters. Check that the slice valves are open (in spa equipment area, if equipped). Turn spa off and then back on. Check if the heater pump (Pump 1 or Circ.) is operational and, if so, make sure it is not air locked. If an error persists, call your Master Spas dealer or service organization.

AOH

Ambient Overheat: The temperature inside the spa skirt is too high and causes an increase of the internal temperature of the control system above normal limits. This can happen in warmer climates, especially if equipment is constantly running.

Simply let the spa rest for an hour before proceeding. Remove spa cabinet skirt panel on equipment side to let control system cool down until error disappears. If partially or fully recessed installation, review if heat is able to be released by air flow around spa, amend as needed. If an error persists with the skirt cabinet removed and open-air flow to equipment, call your Master Spas dealer or service organization.

CoE

Communication Error: Keypad not communicating with the spa control.

Turn power off to spa and back on. Possible loss or bad connection. Call your Master Spas dealer or service organization.

Prr or Pr

The system detects a problem with the regulation probe or constantly verifies if the temperatures read by the probe are inside the normal limits.

DO NOT ENTER SPA WATER! Turn power off to spa and then back on. If an error persists, call your Master Spas dealer or service organization.

UPL

No low-level configuration is present in the control system memory.

Turn power off to spa and back on. If the error persists, there is likely a programming issue. Call your Master Spas dealer or service organization.

If the problem persists, contact your dealer or service organization. (May appear temporarily in an overheating condition.)

Sn or SnS

Sensors are out of balance. If alternating with spa temperature, it may just be a temporary condition. If flashing by itself, spa is shut down. *

If the problem persists, contact your dealer or service organization.

LF

Heater Flow Fail: Several "Heater Flow Losses" have occurred within 24 hours indicating confirmed low flow or complete flow loss. There is not enough water flow being constantly maintained through the heater to carry the heat away from the heating element and the heater has been disabled. (Displays on the fifth occurrence of “HL” message within 24 hours.)

Note the heater is shut down, but other spa functions continue to run normally. Follow action required for “HL” message. The heat capability of the spa will not reset automatically; you may press any button to reset.

dr
