My boiler uses two of the standard 2.4kW kettle elements. The plug that goes into the boiler on both sides often get very hot and begin to deform.

Today's brew was worse though as one actually began to melt and smoke, had to turn this one off about 5min from the end of the boil.

Anyone else suffered from this? They are the leads that were supplied with the elements. I notice they are only rated at 10A, but that only affects the diameter of the cable itself I think?

They are not a really tight fit, could they be shorting slightly?

The problem with high current plug in connectors is that the contact surfaces deteriorate with use - due to tarnish caused by heating.  Each use creates heat, which promotes oxidation of the terminals.  These then have a slightly higher resistance next time they're used, which creates more heat.... you get the idea.

Ultimately, plug in leads are consumables.  You can prolonge the inevitable by cleaning the element prongs with a commercial contact cleaner after use (and once cool) but ultimately the plug will melt and need replacing.  Also make sure that you're using the lead with the correct C15/16 Rating or the lifespan will be significantly shorter.  Your 10A rating is for the plug itself (the cable should be a 1.5mm core size which is good for 18A) and should be ok for a 2.4kW element but no higher.

If you want something long life and maintenance free, hard wire the pins and make the conncetion with a neutrik-type connection.

Thanks Pinto for your detailed response. Sounds like a common issue then. I've done a bit of googling in the mean time and also found that they should be C15 type. I've no idea if these ones are, but I'll buy some replacements that are this rating.

Not sure what the expected life is, but I reckon these ones have done somewhere between 10 and 15 brews, which doesn't sound like a lot.

Can always cut the melted socket off and put this on :

Its cheaper than a proper new c15 lead...

Ordered a couple of new leads, but these could be handy for future reference!

Glad I searched around the site for this thread. I only use the peco boiler for sparge water heating now but I’m fed up and more than slightly worried about the sockets melting on the element lead. Just ordered a couple of these. I’ll report back on how well they perform.

Cheers Jeff.
