Sime Dewy 30/130 30/80 Planet Dewy 90 110 Boiler Ignition Electrode 6221616

Product Overview

The Sime Boiler Ignition Electrode (Part Number: 6221616) is an electrical ignition component designed for selected Sime Dewy and Planet Dewy boiler systems.

Part number 6221616 is identified as an Ignition Electrode, forming part of the boiler's burner ignition system.

The electrode produces the electrical spark required to ignite the gas-air mixture during the boiler's normal ignition sequence.

Correct electrode operation is important for reliable burner ignition and safe appliance operation.

ℹ️ Product Condition Options:

This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished electrodes should be professionally inspected and tested to confirm their condition, insulation integrity and correct operation before installation.

Technical Insight & Common Failure Symptoms

The ignition electrode forms part of the boiler's high-voltage ignition system. During the ignition sequence, electrical energy is supplied to the electrode, producing a spark that ignites the gas-air mixture at the burner.

Over time, electrode performance may be affected by contamination, deterioration of the electrode tip, cracked ceramic insulation or damaged electrical connections.

Possible symptoms that may indicate an ignition electrode or associated ignition system problem include:

• Boiler failing to ignite or fire correctly.

• Intermittent ignition operation.

• Weak or absent ignition spark.

• Boiler failing to complete its normal ignition sequence.

• Ignition-related safety lockouts.

• Visible contamination or deterioration of the electrode.

• Cracked ceramic insulation.

• Damaged electrical connections or ignition lead insulation.

These symptoms do not necessarily confirm a faulty ignition electrode, as similar problems may result from ignition controls, electrical connections, gas supply issues or other combustion components. Correct professional diagnosis should be carried out before replacing the electrode.

Compatibility

This part (MPN: 6221616) is associated with selected Sime Dewy 30/130, Dewy 30/80 and Planet Dewy 90 and 110 boiler systems.

Please verify the exact boiler model, GC number, electrode configuration and electrical connections against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler ignition electrodes are safety-critical components within the appliance's gas ignition system. Inspection, removal and installation must only be carried out by a Gas Safe registered engineer who is suitably qualified for the appliance and work being undertaken.

Always isolate the appliance's electrical and gas supplies as required before carrying out any work and follow the manufacturer's servicing instructions. Ensure the electrode is correctly positioned and connected, and that any disturbed combustion chamber seals are correctly refitted. All required ignition, combustion and operational safety checks must be completed before the boiler is returned to service.
