Our Expert's Opinion
"If you’re experiencing ignition failures, lock outs, or inconsistent flame detection, this part is often the reliable fix."Vaillant 090709 Ignition Electrode
The Vaillant 090709 Ignition Electrode is a replacement part designed to ignite the burner and verify the presence of a stable flame during operation. This electrode provides both the spark for ignition and the flame-sensing feedback that allows the boiler to regulate safe combustion. Over time, electrodes can degrade due to heat exposure and carbon build-up, which can lead to ignition failures, intermittent operation, or error codes. Replacing the electrode restores the correct spark strength and flame detection accuracy, ensuring the boiler lights reliably and maintains optimal efficiency.
Suitable for a wide range of Vaillant boilers, including ecoTEC, VC-W, VKK, and VSC models, the 090709 Ignition Electrode is engineered for durability and precise compatibility. Installation should always be performed by a qualified heating engineer to ensure proper positioning, wiring, and spark gap alignment.
Vaillant provide a 1 year warranty on all spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.
