Boiling water tap and dishwasher in same outlet?

[jb2410]

Morning all,

Dishwasher has died after 10 or so years of loyal service.

Quite fancy a boiling water tap also, dishwasher currently runs off a trailing socket with an isolator above the worktop.

Could I just change this for a double and run boiling water tap and dishwasher both from it?

Conscious the dishwasher is probably fairly high powered when on and I imagine the boiling water tap will be similar to a kettle, but both do run off a (I assume) 13a plug ordinarily!

Advisable or a no no?

We have a double socket as part of the ring main that feed the dishwasher and the boiling water tap with no issues so far.

Super, thank you.

I would expect that even if both were on together it would be unlikely they’d be drawing max current for any length of time long enough to cause an issue.

Neither a dishwasher, nor a kettle , are "high current" in the scheme of things, hence they come with 13A plug tops. You'll find ring mains in kitchens running the entire kitchen - on one circuit, with only the hob/oven on its own.

Same here.

Modern stuff is so efficient. I'll bet the average whole house doesn't draw 32A.

If in doubt (or just for ease), after a fused isolator you can safely spur more than once, so just fit a separate single. I have seen the odd burnt out double here and there.

I would definitely not put both on the same socket/spur.

A dishwasher can draw 2400 watts.
A boiling water tap can draw 1600 watts.

Sod’s Law there will come a time when the dishwasher is drawing max power and so is the boiling water tap. Best case you’ll blow a fuse or trip a breaker.

Worst case - use your imagination.
