Three-day fault finding course

Duration: 3 days

Cost: £200

We are very proud that our three-day generic fault-finding course has been accredited by the Chartered Institute of Plumbing and Heating Engineering (CIPHE).

The three days cover 'How a combi works', 'Multimeter training' and 'Boiler diagnostics'.

  • On the first day, delegates find out exactly how a combi works. Knowing and understanding the sequence of events that lead to the boiler firing up makes it easier to work through and identify where an issue may lie when you are called to a breakdown.
  • Day two is all about using and understanding a multimeter.  Our trainers will explain how to use this valuable tool to carry out safety checks and identify whether components are working properly.
  • On the final day, delegates will put into practice everything they have learned in the previous two days. They will work on live boilers which have been set up by the trainers with faults for them to identify and put right.
