If you have a pool heater, chances are you might have been figuring different ways in which each component works. Pool heaters are designed with several features which communicate to help your heater function efficiently.
The truth is, there is a whole lot to learn about pool heater parts, their functions, problems, and the various troubleshooting steps. One of the major parts we will be concentrating on is the sensor.
However, if you are a technician, chances are you already have existing knowledge about this component and its associated failures. Otherwise, you would need this article to guide you on the different sensor failures and their troubleshooting codes.
RayPak Pool Heater Sensor
Have you ever thought of knowing how pool heaters stop when a certain temperature is reached and picks up again when it is too cold? Yes, you could have inputted the temperature. But how does it know when that temperature is reached? This is where the pool heater sensor comes into play.
Pool heater sensors are made to regulate the temperature of the water coming through your heat pump. The sensor keeps track of the water’s current temperature, so it starts heating when it falls below the required freezing point. The heating continues until it gets to the desired temperature. Then, the sensor signals back to the heater to stop. This heating cycle is what keeps the water temperature at normal to enable you to have a warm feel in your pool water.
Raypak Pool Heater Troubleshooting Codes
Every technology has a built-in database of error codes that provides easy troubleshooting steps to your equipment. Raypak pool heaters are no exception to those codes. And these codes are what have kept technicians come up with a quick solution to your heater problems.
Error codes are never something good. In most cases, they could be signaling a critical message that would require immediate attention. One thing I learned from the past, “Never ignore any error codes that pops-up from your device.” Even if you do not have the device manual, contact the manufacturer or, better still, download a new one from the manufacturer’s website.
You might be wondering where these error codes will be displayed. Almost all Raypak or ray vac pool heaters have a digital display that shows some information about your pool heater. This includes the status and the heater’s error code.
We know it could be difficult locating your manual, so we have compiled a few important error codes to help you all the way in troubleshooting your pool.
Error Code 1: SNS
Error code SNS is an issue relating to the temperature sensor. Sometimes this could be a temporary issue and would fix when the heater goes off. However, the problem could be from the thermostat or voltage, causing overheating. If the water temperature is below or above the normal range, this error will trigger. It could also be that the two thermistors are 2 degrees apart from each other. The heater may be giving false readings if the sensor is not sitting correctly on the JACO fitting.
Error Code 2: BD1
Error code BD1 is a nightmare to most pool owners. It means a “Board Failure.” Board failures are a critical aspect of a heater problem and sometimes could result in replacing the entire board. But first, try turning off power from the switch and source.
Error Code 3: EEP
This error code might sometimes be critical compared to the BD1, and it is caused by the failure of the memory to boot from the processor. First, try to turn off the power source from the toggle switch and the source. If everything fails, replace the board.
Error Code 4: FFL
Raypak pool heater no pilot sensed error is related to error code FFL. When you receive this error message, check if the pilot light stays on when the CFH is normal. If the light stays on, the pilot valve could be open. Replacing the gas valve would fix it. If the gas valve is functioning properly, it could be that the system board is faulty or not performing as supposed. Try unplugging all the wires connected to the board and switch off the heater from the toggle and main switch. Power back on. If it still does not work, change the board entirely.
Error Code 5: PRS
Raypak pool heater water sw open error could have been caused by several factors. The most notable one is water pressure. If the water pressure is low, the heater may only operate for a short time and cut-off. First, it is recommended you clean all your filters and skimmer of any debris. Be sure your pump is running and the water level is at the skimmer.
Most importantly, check the pump’s location and make sure it is not too far away from the pool. If it is more than 5 feet above or below water level, adjust the pressure.
Just like every other error code associated with many technologies today, Raypak heater codes serve a great deal in helping you know the root cause of an issue. Thus, eliminating the time it takes for repair.
