2. Low Boiler Pressure

The Boiler pressure gauge measures the amount of water passing through the central system, which is boiler pressure. Showing the gauge’s needle between 1 and 2 defines that the unit is in the ideal pressure.

But if it becomes low, the unit will stop normal working. Water leaking and bleeding radiator are the two major reasons for occurring this problem. If you are troubled with this issue, fix it by the following steps:

• Now open the valves in order to let normal water flow into the system.
• It’s time to measure the pressure in the gauge. If it reaches one, then the problem is solved.
• Now locate the valves to the previous position. Before tightening it, release some water from the loop to ensure normal water flow.
• Turn on the boiler again, and it is at normal pressure. 

3. Boiler Leaking Water

• Make sure pilot lights are functioning well. If not, relight it.
• Verify that the thermostat is set to “Heat.” Also, always set the temperature higher than the current room temperate.
• Replace the defective pump seal.

5. Radiator Not Heating

Typical reasons for the crown boiler radiator not heating issue are defective zone valve, trapped air in the radiator, defective circulator, or pump seal. It would be better to apply below DIY fixing methods to fix this issue.

• Besides, don’t forget to check the pipeline as well. As because eroded pipe often cause this problem.
• Finally, remove trapped air from the radiator valve.

6. Boiler Noisy Pipes

Some of the common issues lead to the boiler producing excessive noses. The Damaged circulator pump is the main of them.

Solution:

• First, identify where the problem in your crown boiler.
• Replace damaged circulator pump.
• Inspect the boiler and tighten all loose parts.
• Clean out the conductor and heat exchanger properly. 
• Don’t forget to remove trapped air from the pipeline. 

7. Boiler Not Responding To The Thermostat

Crown boiler doesn’t respond to the thermostat due to insufficient power supply, damaged thermostat batteries, incorrect temperature settings, broken or defective boiler, faulty wiring, damaged components, wrong installment of the thermostat. However, you may try to fix this by the below methods:

Solution:

• Then, check if the battery is dead or any loose wires there. Replace the batteries and wires also if needed.
• Also, make sure the proper power supply is in the appliance.
• Install the thermoset in a better location.
• Set the thermostat power always high than the room temperature.
• If all that doesn’t work, contact customer service.
