Utica Boiler Troubleshooting [7 Easy Problem Solutions]
From this article, you will learn about common issues that you may experience with your Utica Boiler. Also, you will learn how to overcome those boiler problems.
1. Not Giving Enough Heat Or System Not Heating
When you turn on your boiler, it provides you with not enough heat to warm your room. Several reasons are responsible for not offering enough or no heat. They are:
- You don’t set the thermostat properly
- The thermostat gets defective
- No power to your boiler
- Radiators not heating
- The chimney flue gets clogged
- Poor electric contact
- You don’t operate the burner properly
- Vent damper not operating
Because of those issues, your boiler doesn’t give sufficient heat.
First off, make sure you set the thermostat above the room temperature. If you don’t know how to reset the thermostat, follow the below steps.
- Set your thermostat to the lowest setting
- Shut down all electric power to the appliance
- Ensure the pilot light is on
- Pull out the front panel
- Turn the gas control knob clockwise. Now, wait for five minutes to clear out any gas. Then, turn the gas control knob counter-clockwise to turn on the gas supply.
- Replace the front panel.
- Now, turn on all-electric power to your appliance.
- Lastly, set the thermostat to your desired temperature level. If you fail to turn on the Utica Boiler, turn off the gas supply. Then, call Utica Boiler tech support for help.
Secondly, inspect your thermostat and change the batteries. If needed, reach out to customer service to solve the issue for you.
If there is no power to your boiler, ensure the electric supply circuit is on. On the other hand, check the steam air vents for proper operation if the radiators are not heating.
In case of a clogged chimney flue, we recommend you hire a certified technician to clear out the blockage from the chimney flue.
To fix poor electrical contact, hire a professional to check all control terminals and wire joints. Also, call Utica customer service if the burner or vent damper doesn’t function properly.
2. Boiler Temperature Is too High
A common reason behind the Utica boiler temperature too high is the taps or central heating system doesn’t circulate successfully when hot water needs to be sent to the cylinder.
Also, a defective pump or blockage with limescale in the system, or a faulty thermistor could be responsible for this issue.
Try to trace out the reasons behind the problem and fix them by following the given solution guide below-
- If the blockage is small, bleeding is enough for your radiators
- When the reason is a build-up of limescale in the system, a chemical flush is needed by your central heating system to make it blockage free.
- If your pump is defective, repair or replace it with the help of a tech
- To solve the faulty thermistor issue, take help from a professional
3. Burner Is Noisy
Your Utica Boiler may make a whistle or a popping sound for multiple reasons. For example, if the gas input is not correct, your Utica will make a noise.
Therefore, the burner will also make a loud noise if there is gunk buildup in the bottom of your boiler.
Make sure the gas input is correct. Also, you should have good gas pressure. To clean the gunk buildup from the bottom of your burner, flush away your boiler.
4. Walls or Windows Sweating
Not enough ventilation is the culprit that makes the walls or windows near the boiler sweaty. If the chimney flue of your boiler gets clogged by dirt or debris, the walls near the boiler will sweat.
Ensure you install the boiler, maintaining the proper clearance. Make sure there is at least a 7″ gap between the wall and the control side of your boiler.
We recommend you hire a professional to ensure proper ventilation. The technician will also help you to clean out the clog from the chimney flue.
5. Safety Valve Leaking
A safety valve, also known as a boiler pressure valve, is one of the most crucial components. But dirt and limescale buildup can increase the pressure inside the boiler tank. Consequently, it may leak the safety valve, causing the boiler to malfunction.
If the safety valve gets defective, we recommend you replace it with a new one. It would be better to call a technician to change the safety valve for you.
2 More Common Utica Boiler Problems & Solutions
Apart from the issues we mentioned, you may also face these problems with your Utica Boiler.
Problem 1: Power Light Won’t Turn On
The power light won’t turn on if any of the boiler power switches are in the off position. So, check all the boiler power switches and turn them to the on position.
If the power switches are in the on position, maybe you don’t turn on the main circuit breaker. So, reset the circuit breaker to fix the issue. On the other hand, if the circuit breaker is in the on position but the power light is not lit, call a professional for help.
Problem 2: Utica Boiler Error Codes
Every boiler or heater will display error codes like E01 or E00 when any components get defective. Below, we provide a list of error codes your Utica Boiler will display if something gets faulty.
|E00||Storage unit PSU parameter not found||> Faulty wire connection||> Check the wire connection|

My Utica Boiler stopped giving hot water, it’s now only giving warm water and for only a few minutes. It does have a expansion water tank. Before I have a expensive technician to the house (we both retired and on Social Security, is there anything I can try myself first
To solve the issue, follow our guide on not giving enough heat section from Utica Boiler Troubleshooting.
Hopefully, you will get the solution.
Wish you all the best.
I just had a new Utica boiler installed. I love it. My only problem is it is way too hot. I’ve turned all my thermostats down to 50 and it is still 77 in the house. It still comes on all the time. The system is a 3 zone unit and all have been calibrated to be the same temp. I’ve even turned the upstairs to Off and it’s still 80+ upstairs. I know not a usual complaint in the dead of winter but it’s annoying my wife. I actually think it is either 1 thermostat or a combination of all three being super old. But the older ones (analog) work the best as long as they are level.
Your Utica boiler overheats because of a defective pump or blockage with limescale in the system, a faulty thermistor. Also, this problem can happen if the taps or central heating system doesn’t circulate successfully when hot water needs to be sent to the cylinder.
As your boiler is new one, try to diagnosis the reasons and fix them by following our guide on the ‘Boiler Temperature Is too High’ section from Utica Boiler Troubleshooting.
Hope you will get the solution.
My Utica boiler has a flashing green backlight. Everything is working but I don’t know why it’s flashing.
Generally, when a boiler senses any problem, it flashes red or green light. It indicates that it’s time to reset the boiler.
Well, to fix it, first, reset your boiler.
If it doesn’t work, take help from a proffesional.
Have a great day.
My Utica boiler is giving code sta8 and the heat temperature is not rising. There is very little heat and after several hours the temperature has only gone up 2 degrees
Utica boiler error code 8 means the return temperature is too low. The reason behind the er may be bad connections, a faulty sensor, or no circulation.
Well to fix the issue, first, check the wiring connection & fix it if you get them loose or faulty. Then, inspect the sensor & replace it if necessary.
Plus, ensure enough water pressure & water circulation & the heat exchanger is clean.
Hopefully, your problem will be solved.
Best of luck!
My utica boiler is noisy when zone valves engage along with water running through pipes.
I purged air from system seems to be quiet for a few days before becoming noisy again.
Usually, a boiler can make noise due to trapped air. When the boiler starts the water heating procedure, the steam is released, the air is trapped in the system & increase the pressure level. Consequently, the boiler makes noise.
Well, to resolve the boiler noise issue, bleed the radiators. To do this, it’s worth hiring a professional.
Hopefully, your boiler noise problem will be solved.
Best of luck!
My Utica boiler reset light is on. The user interface says connecting. Nothing happens. I cannot find anything on this issue in the troubleshooting manual. I press the reset button and nothing happens. It seems sad if the screen is locked up. Other than that this boiler has worked flawlessly.
To fix the issue, it’s worth contacting the Utica customer support center to inspect your boiler to find out the main culprit behind the issue.
Best of luck!
