There’s nothing worse than discovering your boiler isn’t working—especially during the colder months in Stevenage. No hot water, no heating, and a lot of uncertainty about what to do next.
Before you panic, take a deep breath. While some boiler issues can be resolved with simple checks, others require the expertise of a qualified
plumber in Stevenage. In this post, we’ll help you identify common boiler problems, what you can do yourself, and when it’s time to call in the pros.
Common Signs Your Boiler Isn’t Working Properly
- No hot water or heating
- Pilot light has gone out
- Strange noises like banging, whistling or gurgling
- Error codes or flashing lights on the boiler display
- Pressure too low or too high
- Leaking or dripping from the boiler
- Radiators not heating evenly
- Boiler keeps turning off on its own
Quick Checks You Can Do Yourself
Before calling for help, try these basic checks:
✅
Check the Thermostat
Make sure the thermostat is turned up and the room temperature hasn’t already reached the set level. Also, check if the batteries need replacing.
✅
Inspect Boiler Pressure
The ideal pressure is usually between 1 and 1.5 bar. If it’s too low, you might be able to top it up using the filling loop—only if you’re confident doing so. If unsure, don’t risk it.
✅
Look for Error Codes
Most modern boilers display error or fault codes when there’s a problem. Consult your boiler manual to decode the message.
✅
Reset the Boiler
Some faults can be cleared by pressing the reset button—refer to your boiler manual. However, repeated resets indicate a deeper issue.
✅
Check the Power and Gas Supply
Ensure the fuse hasn’t tripped and your gas supply is active. If your gas meter shows a fault or you can’t smell gas, do
not attempt to fix it yourself.
