Doesn't look tgat easy to remove spark leads and rectification. Have you loosened the hex to allow it to move forward to get burner out as it looks loose. I can imagine those leads snapping after a few years
They are always stuck when new, or never before removed. I found using a pair of long nose piers, positioned just below the push on connector, around the electrode stump. levering upwards and twisting the connector, at the same time. I have never used WD40, seems ok but you need to clean up afterwards.
The new design with these two electrodes wrapped in the same rubber… they made it even more difficult to remove. Absolute rubbish design. The amount of strength that is necessary to use with pliers and screwdrivers until the bloody electrodes are disconnected is incredible.
Makes no sense to me. Most of the time the rubber gas pipe needs changing so just disconnect at gas valve swing whole fan assembly and top section out.
Typical Worcester. They’ll never learn. They could have relocated those electrodes to the front of the heat exchanger. But oh no, they leave them in a position that’s an absolute pig to squeeze your hand into, and still use rubber that welds itself to the electrodes. No wonder I don’t know a single installer who fits their shite anymore.
Seen this, it is very intimidating to service. Reason why most of the Worcester have worked on are not service correctly, because some Engineer has no clue where to start from and end up shredding your hand. Really bad design
