Course outline

Boiler fault finding courses

The Gas Boiler Fault Finding course has been designed for installers who are keen to improve their fault finding skills; whether that be to provide a better fault finding and repair service for their customers or to move from installation altogether, into a servicing career. This course also caters for new students with little or no knowledge of gas boilers, making their first steps towards a career in the heating industry.

If you are looking for the right boiler course first time, then this is the solution for you. Our course can help you identify, diagnose and repair faults on heating systems and gas boilers, confidently and competently.

Many people looking for boiler training courses will go from one place to another, desperately searching for the right course that covers everything they need to know. Instead of spending years going through different courses, make the right decision and opt for the best oiler repair and heating breakdown course. No more having to search for the course that has it all; these boiler repair courses will teach you everything you need to know about underlying principles and the design technology needed, to correctly diagnose boiler and heating system faults.

The Gas Boiler Fault Finding Courses are divided into 3 modules:


Module 1 : Basic Electrical Understanding

The majority of electrical fault finding, associated with plumbing and heating systems, is centred around the operation of boilers. Trends in the domestic heating market are rapidly changing, therefore more heating system components are now contained within the centralised boiler housing; as opposed to being installed at different points of the heating system (such as with traditional S and Y plan heating and hot water systems). This is particularly the case with combination boilers, which are now the most popular form of boiler and one that installers and engineers will come across more regularly whilst fault finding.
Multimeters are instruments that allow the user to test, or measure, electronic components. Therefore, it is vital that you learn how to conduct tests on boiler components using a multimeter, in order to give you a good idea of what may be wrong, what the faults are and how the boiler can be repaired.

The areas covered on this module include:

– Multimeter Testing Principles – Resistance and Continuity
– Multimeter Testing – Voltage, Alternating and Direct Current
– S & Y Plan System Wiring


Module 2 :  Component Testing

With the huge amount of combination boilers installed, as well as the major or minor variations that can occur, it would be impossible to specifically describe each and every component for all the boiler variations. Luckily, all of the different components carry out obvious actions and, in most instances, will share basic functions with its counterpart in other combination boilers.

It is important to have an adequate understanding so that you are able to recognise each component, along with how it works and how it relates to the other components within a combi boiler. Once a fault has been located, and the component(s) causing the disturbance has been verified, it can be repaired.

The areas covered on this module include:
– Boiler sequence of operation
– Boiler component testing
– Domestic heating controls testing


Module 3 : Boiler Fault Finding

Fault finding and repairs on combi boilers always require a methodical approach; there is a logical and efficient method behind the diagnosis of combination boiler faults. First, safe working procedures must be followed and electrical safety tests must be carried out. Then, the problem can be found and repaired.
The logic behind boiler fault finding does get easier with practice, especially as your approach to each task develops. Finding faults with combination boilers revolves around solving the problem; the problem being that the boiler is failing in either its heating or hot water role, sometimes even both. However the fault is found, and whichever fault diagnosis procedure is used, the objective is always to achieve:
• A fast and accurate diagnosis
• A minimum shut down time
• Effective repairs, as soon as possible
It is therefore important to always use a logical approach to fixing the boiler, so that it can deliver its fully capability.

The areas covered on this module include:

– Boiler Fault Finding Logical Method
– Boiler Fault Finding Generic Method
– Typical Faults
