02 — SYMPTOMS
Most calls we get are about boilers 10 to 15 years old, and most start in the first cold week of the season.
Ignition failure, a worn circulator pump or a control fault in an ageing boiler.
Check the thermostat setting and the boiler's power switch. Don't remove the cover or repeatedly reset it.
A sticking diverter valve, faulty flow sensor or deposits in the plate heat exchanger.
Check whether the display shows an error code and note whether the problem affects every tap.
Reduced boiler output, an ageing pump or heat exchanger deposits. Cold snaps can make the problem more noticeable.
Confirm the thermostat schedule and record the temperature shown on the boiler display.
An expansion tank problem, pressure relief valve seepage or water escaping from the system.
Note the pressure when the boiler is cool. Don't keep adding water to compensate for recurring pressure loss.
An expansion tank that has lost its air charge, a faulty filling valve or a pressure relief valve that needs attention.
Read the pressure gauge and note whether dripping happens only while the boiler heats. Don't block the discharge pipe.
A leaking internal connection, pump seal, valve or condensate assembly.
Keep clear of the water and electrical parts. If leaking is active, call for guidance rather than opening the boiler.
A worn ignition electrode, flame sensor, gas valve or another boiler safety-control fault.
Record any error code. Don't repeatedly reset a boiler that locks out or attempt to light it manually.
The code may indicate ignition, pressure, fan, sensor or condensate trouble. Its meaning depends on the model.
Photograph the display and note the boiler brand and model. A boiler fix near me visit is easier to prepare when we have the exact code.
Short cycling may come from control settings, temperature sensors or restricted heat transfer.
Note how often the boiler starts and stops. Schedule an inspection if it continues, even when the house remains warm.
Ice blocks the condensate drain on a condensing boiler, causing a safety shutdown during severe frost.
Look for an accessible outdoor condensate pipe from a safe position. Don't use flames, boiling water or tools to break ice.
Blocked venting, a frozen condensate line or an ageing component failing under sustained winter demand.
From a safe location, check whether snow is obstructing the outdoor vent. Record the error code and call for assistance.
An older boiler can make very different sounds. Here's what they may mean before you describe them to a technician.
Deposits inside the heat exchanger or poor circulation can cause rumbling or sharp knocking.
Book soonAir moving through the boiler or unstable water pressure may produce bubbling sounds.
Can waitA restriction, escaping pressure or an internal valve problem can create a high-pitched sound. A suspected gas leak needs immediate evacuation.
Call nowThe ignition system may be attempting to start but failing to establish or detect a flame.
Call nowSmell gas or hear a CO alarm? Leave the house and call 911 first.
