You may have a Spa Builders control system which was commonly used by Arctic Spas throughout their range.

Turn the hot tub off at the mains to reset it. If 'HL' returns again on the display you need to feel the heater tube. If the heater tube is not hot either, you have most likely got a faulty hi limit temperature probe (attaches to the heater), or a faulty PCB.

It might also be wothwhile checking the hi-limit probe connection on the PCB, these have been known to corrode and cause errors before.

The temperature probe is the cheapest item so try replacing this first.

Kind Regards,

SOURCE: Panel reads "water sensor opened"

I had the same problem. The water sensor is on a pipe running into your pump. It will have a circular clamp around it. Remove the clamp and pull the sensor out of the pipe. The wires should run into your control box. disconnect the wires and replace. My water sensor was part 7790. Not sure if you have the same one. Do an online search. bestbuypoolsupply.com has them for $50 plus 9 for shippng. Hope this helps.

SOURCE: pool and spa heater will not turn on, low pressure on display

1) check the fuse on the transformer. You will get "low pressure" if the fuse is blown.
1a) remove front panel with flat head screw driver turning both big screws 1/4 turn clockwise
1b) look up under the 1 remaining front piece for 2 screws (one on each side). remove them and the 1 small panel slides down
1c) transform is directly in the center of this compartment
1d) red wire on transform has a black fuse case - twist open and check fuse (with an ohm meter it should read a dead short if it is working).
1e) if not working - replace with standard 250v 2a bus fuse.
2) it really is low pressure
2a) backwash pool or at least make sure pressure in filter take is not too high (high filter tank pressure == low water pressure in heater)
2b) if you have a bypass valve make sure it is not in bypass mode so most all pressure from the pump is going tothe heater
2c) right next to the transformer is the pressure switch. It has a small copper tube attached to the back and 2 wires in the front. Put an ohm meter across the two leads on this device. With the filter off it should be open, with the filter on it should be closed (short). If not either the copper tubing is clogged, the switch is faulty, or there is not enough water going through the heater. The amount of water that goes into the heater is adjustable and the water pressure switch is also adjustable. The owners manual explains how to adjust both but neither should need adjustment unless you have a special configuration (explained in the manual).

My Apollo Rainier hot tub's heater doesn't seem to work - I get a FH message on the display. Please help!!!


HL generally stands for high limit fault which means a sensor is opening the heater circuit due to too high a heat reading. Common causes for such a fault start with poor water flow due to dirty filters which in turn allow the element to overheat. If necessary, replace the filter elements to restore proper flow.If flow issues are not the problem, try looking at the heater itself however you should probably call out a professional at this point as most remaining issues to check are within the controls and the heater and if you are not familiar with working on these components you should avoid trying to repair this yourself.

The HL indicator light comes on and I can not get it to reset. I shut spa off and the HL light was on again when I checked an hour later. I live in Wisconsin and don't want my tub to freeze. Tub was used...


It sounds like a flow issue. When the HL comes on, its sensing a higher temp than it is supposed to. This is usually caused by bad flow in the circulation pump.

The most likely cause of the bad flow in residential spas, is a bad filter element. Even if a filter looks clean, they do get clogged with particles we cant see. To test this, make sure the spa is free of debris, and remove the filter element. Run spa for a while and see if the code comes back. If it doesnt, get a new filter.

Otherwise the pump could either be failing, or clogged. Check this next.

Finally if these dont work, check the temp sensor (thermistor) .

I have my hot tub plugged in for 3 days and the water is still cold, how long does it usually take to heat up a 8 man arctic spa?


If the cover and doors are on and everything is working then it should take no longer than about 8 hours.
It could be something simple like the heater is unplugged, or more complex like an airlock or faulty pump motor.
If you can't get service from your local Arctic Spas dealer, the head office service department can be reached through their worldwide corporate website, www.arcticspas.com

I have a 2003 Arctic spa and have changed the heater. I have a HL sensor error on the panel but the tub is cold?


HL usually means that the heater is working and there is no water passing through it, do you get a flo error message before the HL,I had the same problem, mine was the flo switch
