Expert boiler fault diagnosis
When a boiler stops working properly, the symptoms can point in several directions. You may have no heating, no hot water, odd noises, low pressure, a leak, a faulty thermostat or a pilot-light problem that will not stay sorted. We begin by reviewing the symptoms and fault codes, inspecting the appliance and controls, testing the relevant components and tracing the underlying cause. With Lewken Limited, that repair work covers all makes and models, including Vaillant, Potterton, Bosch, Baxi, Ideal, Glow Worm and Megaflo. In Ashford, the point is to work out what has actually failed before parts are ordered or assumptions are made, because a boiler that keeps cutting out rarely improves when people simply press the reset button harder.
Repair the failed part and test the result
Once the fault is identified, the fix may be an adjustment, cleaning work or replacement of worn valves, seals, pumps, thermostats or other failed parts. When you book Lewken Limited, we explain the likely route clearly, along with the limits of what can sensibly be repaired on an ageing or badly deteriorated appliance. We then test the boiler after the repair so you know the system is functioning again rather than just sounding more hopeful than it did an hour earlier. The indicative repair range is £100 to £1,000 or more, with the final cost shaped by the nature and extent of the fault, the parts required and the labour involved in reaching and replacing them.
Frequently asked questions
What boiler faults do we repair most often?
Common problems include lost heating or hot water, faulty thermostats, blocked or broken pumps, failed pressure-relief valves, unusual noise, leaks and pilot-light issues. We use those symptoms as a starting point, then test the appliance to identify the underlying fault.
Do we work on different makes and models?
Yes. We cover all makes and models, including Vaillant, Potterton, Bosch, Baxi, Ideal, Glow Worm and Megaflo. The important part is diagnosing the exact fault on the boiler in front of us, because similar symptoms can still come from different failed components.
How much can a boiler repair cost?
The indicative range is £100 to £1,000 or more, depending on the nature and extent of the fault, the replacement parts required and the labour involved. We explain the repair route clearly, so you know whether the issue is relatively minor or part of a bigger problem.
