If you notice that your Bullfrog Spa isn’t heating up, here are some possible reasons why it might be failing to heat.
One possibility is that the HL High Limit circuit has tripped.
Check electrical components for corrosion. Another potential cause could be that you have a freeze-protection mode.
Let’s examine some of the major reasons, as well as some helpful tips to make your Bullfrog Spa to start heating up again.
HL High Limit circuit has tripped
If you find that your Bullfrog spa is not heating up, you may have a faulty high limit switch. High limit switch trips whenever the temperature of the water in the spa increases beyond a certain point.
If this happens, you should reset the circuit breaker or seek assistance from a qualified electrician. You should also check the electrical service for any problems. In addition, you may have a blown or damaged 20A or 30A fuse.
The problem could also be caused by a bad circulation pump, low-speed pump, or incorrect circulation pump.
Also, make sure the slice or ball valve is open, and that the footwell suction is clean. If these problems persist, replace the pressure switch. Otherwise, check the heating element. If this doesn’t fix the problem, you should check the high-limit circuit.
If the HL High Limit circuit has tripped, the problem is most likely related to a malfunction in the heater circuit. Check the panel for a red button. If you don’t see the button, you can press it and see if the heater indicator light comes on. If it does, you might have a bad element close to the sheathing.
If the heater circuit is tripping, the problem may be related to the high limit switch. This circuit protects the hot tub heater from overheating, resulting in scalding water and hot tub meltdown.
The high limit switch is calibrated to detect unsafe temperatures and shut down the heater. Unless the switch is manually reset, it could be a serious health hazard to bathers.
Check for corrosion in electrical components
If you have a hot tub that is tripping the breaker, you may want to look at the electrical connections inside the spa. Make sure the wires are secure, and check the spa for corrosion.
If you suspect that a part is corroded, you should replace it as soon as possible. If you’re unsure, you can always have a professional electrician come out and take a look.
The electrical components of your spa should be free of any signs of corrosion. If you can see white powder around the components, the problem is caused by corrosion. The ground wires and the panels should be free of dust.
The elements of the control box should be free of corrosion, too. If you spot any of these issues, replace them immediately. If you don’t see them, the spa may be too old or has been abandoned.
Another common cause of heating problems in a spa is a heater failure. Properly maintaining the water chemistry in your hot tub will prevent your heater from failing.
When you’re shopping for a replacement heater element, be sure to buy one that matches your spa’s kilowatt rating.
Buying an incorrect one can cause problems, such as corrosion on the heating element. Check for bad spacing and epoxy seals on the terminals.
You can use a longer flathead screwdriver or a short pry bar to remove the door. Carefully push it from the bottom of the spa.
Make sure that the door does not rest on electrical wiring or electrical switches. If it is, you can disconnect them.
Once you’ve disconnected the electrical wiring, you can remove the door. If you’re unsure, you can also check the wiring before replacing it.
Check for flow of water through the heater
If the water in your spa does not seem to be flowing properly, this might be a sign of a problem with the heater. The heater controls should be adjusted and the water level should be properly maintained so that it does not overheat.
The water level must be regulated to the mark indicated on the filter assembly or else the pump will shut off.
If the water level is not correct, you should adjust the water level and clean the filter. If the pump does not turn on, you could have a defective motor.
Then you should call an authorized Bullfrog Spas Dealer to repair your heater.
You can also check the electrical settings. Most new spas have a built-in thermostat with a temperature sensor attached to the circuit board, which you can turn off and on from the topside control panel. However, if the thermostat is old, it is possible that it has corroded or has internal problems.
Checking the thermostat for short circuits is one of the easiest and most effective ways to diagnose a spa’s heater.
You should also check the water levels in your spa regularly. Make sure that all the chemicals are at the proper levels.
In freezing weather, you should never leave the spa without power. Always remember not to drain the water, as this can lead to frozen pipes.
In the meantime, you should use the SpaGuard filter cleaner to clean the pleats of the filter. It will keep the water in your spa warm longer.
The water level in your hot tub may be too low to run the heater properly. If the level is too low, you may have a faulty pressure switch. If this does not work, you should consult a technician for help.
If you can do the job yourself, this may be a quick fix. However, if you are not comfortable with electrical systems, you may want to hire a professional.
Check for a freeze protection mode
Before you turn on your electric space heater, check for a freeze protection mode in your bullfrog spa.
You never know when a power outage could cause your spa to freeze solid. It will be extremely difficult to heat it up and circulate water when it is frozen. It will also lose its ability to heat itself.
Fortunately, there are several ways to prevent freeze damage. Follow these tips to keep your spa safe and functional throughout the cold weather.
If you notice the door is stuck in the closed position, you should try removing it.
Usually, the spa will have a snap feature to prevent this. Alternatively, you can use a longer flathead screwdriver to pry the door out. You can also use a short pry bar to pull it out from the spa.
If it does not open, contact a Bullfrog Spas Dealer for help.
If you notice that your spa isn’t fully heated, check for the freeze-protection mode on the control panel. If the heater is not working properly, then the problem could be the sensor or the pump.
To fix this, call the hot tub assistance line and have them check your model.
It may also be an issue with the topside control. If this doesn’t work, contact the manufacturer to receive additional information.
If your Bullfrog Spa has a freeze-protection mode, you should turn it on before the cold weather hits. It may activate the pump if the temperature in the spa falls below 40 degrees.
This is usually an indication that the spa is in a freeze-protection mode.
When it detects this, it will automatically turn on the blower and pumps to keep the temperature at an appropriate level.
Conclusion
To prevent freeze damage, you should regularly check the water level in your spa. Make sure the chemicals are at their proper levels.
In cold weather, never leave your spa without electricity. This could cause frozen pipes.
You should also avoid letting water drain out of your spa, as it can lead to freezing.
When winter comes, you can expect the water temperature to drop dramatically, making your spa unusable.
