5 Polaris Water Heater Problems & Their Solutions
Here are the most common Polaris water heater problems and their solutions. This discussion will help you to effectively deal with your water heater problems within minutes.
1. Unusual Noises:
Water heaters produce noise when they are operating. Not all types of noise indicate trouble. But, you should not ignore any type of unusual noise.
Noise caused by sediment buildup is one such problem that requires attention. When sediment builds up at the bottom of the tank, it creates an unusual noise. Too much sediment build-up can even lead to premature tank failure.
To fix this noise, you have to drain and flush the tank. Here’s what you can do:
- Safety comes first. Before jumping into the main process, turn off the electric supply of your water heater. Then shut off the gas valve
- Now, turn off the cold water inlet valve
- Turn on the nearest hot water faucet
- Take a hose and connect its ends to the drain valve and to the drain
- Open the water heater drain valve and drain the hot water from the tank
- Flush the tank with running water to remove the sediments
- Finally, close the drain valve and fill the tank with water again
After completing these steps, check the heater by turning it on.
2. No Green Light:
If there is no green light when the heater is powered on, it is a matter of concern. You may even have to call Polaris water heater tech support to solve this problem.
But before doing that, follow these instructions:
- Check the wire connection and see if the 120V is connected to the black wire. The L1 server should be connected as a ground wire
- Inspect the 24 VAC on the transformer. Replace the transformer if it’s defective
- Check the 24V in the terminal block. If you notice any defect, change this part as well
- Finally, if nothing works, change the blower cover safety switch
This should light up the green light when your Polaris water heater is powered on.
3. No Yellow Light:
If you notice that the yellow light of your water heater isn’t on, here’s what the Polaris water heater manual tells us to do:
Checking the set pot:
- Set the temperature at the lowest settings. Then, set the ohmmeter at X1
- After that, remove the orange wires from the t-stat board and see if the reading says 20,000 ohms
- Set the dial to the highest setting
- Make sure the resistance drop to zero from the highest setting
- If the reading is not like this, change the set pot
Reassembling the black wire:
- If changing the set pot doesn’t solve anything, try reassembling some wiring
- Remove the black wires from the t-stat board and test the black sensor wires
- The water temperature in the tank must match the appropriate reading
- Change the sensor or the E.C.O, if the reading is not perfect
Reassembling the yellow wire:
- Make sure that the yellow wire is connected to the ground and matches the 24V module
- If it doesn’t, then change the yellow wiring
- Replace the thermostat circuit board
After getting these things right, the yellow light of your Polaris water heater should be on.
4. Polaris Water Heater Leaking:
A faulty Polaris water heater blower motor can cause your water heater to leak. Such leaking can lead to disaster because there is electric wiring in the system. This is why it’s important to fix this problem.
Here’s how you can fix the water heater leaking problem with 3 steps:
- Find the shut-off valve at the top of the tank and rotate the valve to turn off the water supply. You can shut off the main water supply as well
- Open the tub spout to relieve the pressure of hot water. You can use the level of the TP valve as well.
- If these 2 steps don’t solve your problem, turn off the gas or the electric signal. Then, drain the water heater using a garden hose
While you are doing these, be aware not to touch your heater while it is still connected to the electricity.
5. Drain Valve Leaking:
If the drain valve of your Polaris water heater leaks, it can be problematic. But, this problem is easy to solve. Just take a rubber washer and use it to seal the tank. And now you have fixed the leaking drain valve.
If you can keep the above discussion in mind, you shouldn’t have any problem dealing with the most common problems of Polaris water heaters.
3 Major Polaris Water Heater Error Codes & Their Meaning
Polaris water heater is a very user-friendly device. Not only does it work with efficiency, but its features also help the users to maintain the overall device.
One such convenient feature is the error codes that come up on the water heater display. The diagnostic system of the Polaris heater can detect problems and flash signals accordingly. If you know the codes, it can save your water heater from heavy damage.
And if you don’t know the codes yet, you will in a moment. Here are 3 major error codes of Polaris water heaters and their meaning.
Error Code 1: Pressure Switch Closed Failure
This error code means that the pressure switch has failed to close properly. This indicates that the ignition control module or the ICM is unable to detect any fresh air in the Polaris water heater. No fresh air means no combustion. And as a result, your device will fail to function.
In this case, the problem is probably with the pressure sensor valve. If too much dirt gets clogged in the pressure sensor valve, this error code will flash. So check for dirt in the pressure sensor valve and clean it thoroughly.
Error Code 2: Pressure Switch Open Failure
Polaris water heater error code 2 indicates malfunctions in the pressure switch. It means that the ICM or the Ignition Control Module has failed to test the air pressure of the incoming airflow. This is happening because the system is unable to close the pressure switch.
This results in a scarcity of air inside of the unit. Eventually, the water heater fails to start a burn cycle due to the unavailability of oxygen. This error code can mean dirty air filters as well.
In case of error code 2, you can try doing the things. Firstly, see if there is a stable power connection. This problem can occur in case the 24Vac isn’t across the pressure switch. Check for cracks in the PVC tubing. There can be leaks as well. Fix any form of cracks.
Lastly, check the exhaust/intel air vent. A clogged air vent can be the reason for error code 2. So, thoroughly clean the vent and make sure there is nothing stuck there.
Error Code 3: Failed Ignition
Polaris water heater ignitor problems are actually quite common. When the ignitor fails to light up, or just stops in the mid-way, Polaris water heater error code 3 appears. Polaris water heater distributors can solve the issue of American standard water heaters, not lighting. But, solving a failed ignition can be tough even for them.
Despite being a complicated issue, if you know the tricks, you can easily deal with Polaris water heater error code 3. You just have to reach the ignitor and examine it thoroughly.
You have to:
- Look for dirt and debris
- Look for leaks in the gas pipe
- Look for clogging in the ignitor and burner
Look for the problem and take adequate measures. You have to make sure that there are no cracks, leaks, or clogged dirt. Knowing about these 3 error codes will save your water heater from severe damages. However, these are not all. There are 5 more minor error codes as well:
Here’s an overview:
|1||Faulty Gas valve Hardware||Look for leaks and fix the crack/|
Change the gas valve
|2||Faulty Flame Sense Hardware||Change the hardware|
|3||False Flame||Shut off the water heater and restart it after 15 minutes|
|4||Faulty Ignition Control Hardware||Check for cracks and debris|
|5||Faulty Ignition Control Software||It’s better if you call an expert at this point|
If you know about all these error codes and the actions they require, you will have no difficulty using your device.

The gas valve controls the flow of gas and thus. It basically controls the water heater. You probably understand now just how important this part really is. This is why it’s important to make sure the gas valve is okay. For this reason, if you find any trouble with it, have a new gas valve & replace it.
Here’s How to Replace the Gas Valve:
- Turn the temperature dial counterclockwise and set the settings to the lower option. Then, turn off the electrical power and the gas connection as well.
- Remove the pressure tap from the gas valve, but don’t disconnect the hose.
- Remove the head screw that’s holding the electrical plug. Then, remove the plug from the gas valve.
- After that, remove 3 of the T-25 Torx head brass screws. These screws basically attach the gas valve to the venturi manifold.
- Remove the gas valve from the unit. But, don’t remove the rubber gasket. Keep it attached with the valve.
- Now, It’s time to reattach the gas valve. To do that you have to remove the O-ring from the flange first.
- Attach the new O-ring that came with the valve kit
- Reattach the elbow flange that you removed earlier. Reattach it tightly to the gas valve. Place the screws accordingly.
- Attach three T-25 Torx screws through their designated holes in the venturi manifold flange.
- Install the rubber gasket perfectly.
- Place the gas valve and screw it in its position with a T-25 Torx wrench.
- Reconnect the pressure tap and the external gas supply line to the new gas valve
- Reconnect every line and turn everything on to make sure the water heater is working properly
- After making sure that the water heater is properly working, reinstall the access door
And just like this, you will have perfectly replaced the gas valve. This is a very important part of maintaining the Polaris water heater. So, do it with utmost care. If you can maintain these 4 parts regularly in the methods discussed above, you will be able to use your Polaris water heater for a really long time.
