Dishwasher Fuse.

[Bigbad]

Can anyone tell me what amp fuse should go in a dishwasher?
Mine stopped working, so I replaced a 3 amp with a 3 amp and it still didn’t work, but works with a 5 amp.
Is this OK?
It’s hard wired, if that makes any difference.

Thanks.

Do you mean a fuse on your consumer unit ?

[douglas9401]

The fuse will have to be heavy enough to carry the current needed by the heating element to produce hot water in the machine.
It should be noted in your instruction book.
A 3 amp fuse is generally for things table lamps.

Now that I think about it you may have replaced a blown 13 amp fuse (brown) with a 3 amp (red) and that hasn't been able to cope with the draw.

I don’t know what a consumer unit is, Donny!
It has a switch with a fuse, on the wall. I always thought this was called ‘hard wired,’ but being a DIY thicko, I could be wrong!

No instruction book, Douglas. Moved in a couple of months ago, and no book left.
May have to look for a downloadable manual.

I’ll have to check back here this evening, now, but thank you both for your answers.

am no electrician but am sure it should be a 13amp fuse in the box on the wall.

Consumer unit is modern language for the old fuse box under the stairs :-)

Dishwashers usually have a high-power element for heating the water, so a 13amp fuse is most likely.
Portable appliances have a plug at the end of the lead with a fuse in the plug. Fixed appliances, in theory, should be wired into a fused outlet - yours is done properly. It just makes it more inconvenient if you replace them but is safer; you may have seen someone on here the other day saying that the plug on one of his appliances was sparking - a fixed cable is safer.

What power does it say on the back ? That should give a clue.

Thanks for the answers.
I put a 13 amp in.
So far, so good. I'll keep an eye on it.
