#Hydro quip spa error codes code#

Remove the spa cover and allow the water to cool.

Check the water temperature with an accurate temperature thermometer.

Note: A common programming mistake is overlapping filter times that may cause the spa to filter continuously.

In extremely hot weather, check for proper cabinet ventilation.

Clean the filter(s), waterline skimmer and footwell suction for any blockage.

The following is a list of most probable causes of this message. In rare cases (usually warmer climates), the circulation pump may also cause overheating. Note: Overheating may occur if the low-speed pump is set to operate for extended periods of time, or if the incorrect pump is installed. These indicate that the spa has shut down due to an overheat situation: The Spa or Hot Tub Panel Displays: HH, OOH, OH, OHS, OHt, HL, HiLi, Sn2, Sn3, tS, Ht, Blinking LightsĪt least one of the sensors has detected water temperatures of 110 degrees or higher inside the heater. In most cases overheat issues are related to the relays on the circuit board, or the temp sensor has failed and will need to be replaced.

Then power the system back up, if the error code goes away, the problem was either a dirty filter (clean or replace) or too many jets were closed off. Shut the spa power off, remove the filter and make sure all the jets are open. Depending on where the temp sensor is mounted usually in the wall of the spa in a sensor mount, you could have a flow issue. If your spa is not overheating and you are getting the above error codes then a couple of things need to be investigated. Then re-start the hot tub, if the error code goes away, the problem was either a dirty filter (clean or replace) or too many jets were closed off.

If however you have the fault then the first thing to do is shut the spa down, do not empty, remove the filter and make sure all the jets are open (as best you can). Rule number 1 is to always fill the hot tub after a drain down by placing the hose pipe in the filter housing suction fitting (remove filter) this fills the hot tub from inside to outside, rather than placing the hose pipe in tub, (this fills outside to inside) and is the primary cause of FLO errors. The fundamental reason is water flow through the spa control system, if the water is not flowing at a rate to satisfy the switch, it will result in one of the error codes above. These error codes are caused by a variety of reasons. These codes are related to flow issues or the pressure switch/flow switch and are by far the most common error codes. SL = Sleep mode Brett Aqualine Control Systems for Spas or Hot Tubs: SE = Spa operating in Standard-in-Economy Mode. (Displays when first powered up after refill).

ILOC = Interlock failure - possible pump or ozone spike.

Pr = When spa is first actuated, it will go into Priming Mode. (Displays on third occurrence of "dr" message). Heater is shut down, but other spa functions run normally.ĭr = Inadequate water detected in heater.ĭry = Inadequate water detected in heater. (Displays on the 5th occurrence of "HFL" message with 24 hours). HFL = Substantial difference between temperature sensors detected. If display shows only this message (blinking) spa is shut down. If alternating with temp, may be temporary condition. Sensor plugged into jack B is not working. Sensor plugged into jack A is not working. ICE = Potential freeze condition has been detected One sensor has detected 110✯.įlo = Improper flow or pressure switch malfunction Pd = Power supply, unit running on battery backup
