WELCOME TO Errors TUTOR
dCPSystem checks for DC power relay (master control relay) activity. Code dCP is displayed if error is found. Usually the board must be replaced. Could be low current to spa or transformer problems.
HtSWater Temp-Hts-Water Temp, tS-0-ts, or tS-255-Ht-Oht-tS- System checks the integrity of the water temperature sensor. If the temperature sensor has failed, one of these errors will show on the topside. Usually needs a new temp sensor. Sometimes the board itself has failed.
FLOSystem checks for water flow through the circulation/filtration and heater plumbing. During this process, the system checks to see if the circulation pump has input current. If an error is detected, the topside control displays the code FLO-Water Temp-FLO. Heater is deactivated. Filter pump may have lost prime and is overheating and stopped running or the filter pump cord is disconnected. Automatic reset will occur if this condition is fixed faster than ~ 5 minutes. Manual reset is requested if this condition has been in place more than 5 minutes. Check for proper water level, pump is primed, leaks and/or clogged filter. Check for filter pump cord connection. Usually means circ pump has failed.
PS2System checks the pressure switch for switch open with the circulation pump off. System checks automatically for this condition every 96 hours. If the error is detected, the topside control displays the code PS2-Water Temp-PS2. Heater and circulation pump are deactivated. Automatic reset will occur if this condition is fixed. Pressure switch may need to be adjusted or replaced or water level is too high.
PS1System checks the pressure switch for switch closure with circulation pump on. If an error is detected the topside control displays PS1-Water Temp-PS1-. The heater is deactivated. Automatic reset will occur if this condition is fixed in less than ~ 5minutes. Manual reset is required if this condition continues for more than 5 minutes. Try removing the filters and restarting system. If PS1 discontinues, replace filters. If you do not see water movement, circulation pump likely failed. Replaced. If you see water movement and filters are out but PS1 is still present, replace pressure switch.
FCFreeze condition. System checks the water temperature for a reading at or below 60deg F. If below, the topside control displays the code FC-Water Temp-FC-. A potential freeze condition has been detected (60 deg F or below). No action required. The system will automatically energize the heater. The heater will be energized even in the ECO mode. The spa will automatically bring the water temperature up until the spa is out of danger. When the water temperature in the spa is equal to or less than 50 deg F both pump relays are energized for 5 minutes (heater is deactivated during this time), heater is energized for 20 minutes again (pumps are deactivated during this time) and this cycle is repeated until the water temperature is equal to or above 60 deg F.
HtHigh temperature condition. System checks for the spa water temperature equal to or above 110deg F. If a water temperature equal to or above 110deg F is detected, the topside control LED readout flashes between the spa water temperature and Ht. The Air Blower (if equipped) is automatically energized to assist in lowering water temperature. The blower will be deactivated after the spa water temperature drops below 107deg F. This case may be due to excessive single speed pump(s) operation, i.e. resetting the Jets1, Jets2 (if equipped) continuously after each 20 minute shut down cycle until the spa water reaches this temperature. Allow time for the system to reset the spa. If Ht returns and topside temp is correct, usually means board must be replaced.
OhtOverheating condition/watchdog. System checks for the spa water temperature equal to or above 120deg F or the heater enclosure temperature is equal to or above 125deg F. If either the spa water temperature is equal to or above 120deg F or the heater enclosure temperature is equal to or above 125deg F, the topside control display flashes Oht-Water Temp-Oht and the entire system is disabled. Oht condition requires Manual Reset action either by pushing the WARMER and COOLER buttons simultaneously, or by turning the main power off and then back on. The heater or water high limit switch cannot be reset until the heater enclosure temperature drops below 123deg F or water temperature in the spa drops below 117deg F. If actual water temp is same as topside, likely must replace board.
