Reported/Observed Symptom:
Job Report: Ideal Logic Boiler Service in Louth LN11. Customer was concerned boiler was making loud whistling sound during use. No issues with boiler functionality - heating and hot water were good. Customer stated no smell of gas or any other issue. Only issue was noise - but was loud enough to make customer panic.
Fault Code: None
Diagnosis/Notes:
I've previously experienced this fault with Ideal Logic boilers. Venturi and injector can block with dirt and debris - have even seen bumble bee get trapped and die within the venturi opening (insects fly into the boiler case through the flue chimney and can become trapped.)
Advised customer their boiler will require a strip service and clean.
Disassembled and cleaned the venturi / injector with wire wool.
Performed a full strip service, flushed the main exchanger and condensate trap.
Burner gasket is only 2 years old and it's in good condition. Ideal recommend changing the gasket every 5 years / when required, so a replacement was not necessary.
Fan and gas valve in good condition - PASSED
Inspected boiler case and seals. They're in good condition - PASSED.
Reassembled the boiler and tested.
Gas working pressure 21 mbar - PASSED.
Flue gas analysis within specifications - PASSED.
Testing boilers safety devices. Air pressure sensor and flame sensing device tested good - PASSED.
Resolution
