After a recent refurb where some of the electrics were also changed (including consumer unit and a full rewire), I noticed that when using the oven it would sometimes trip the kitchen fuse. Where should I start looking? Here's a bits of information:
The oven is an Indesit DFW 5530 ix UK (not new) https://www.electricalspecs.co.uk/indesit-aria-dfw-5530-ix-electric-oven-specs/
It is connected to a socket with a 13 Amp fused switch
It is part of the whole kitchen circuit (on a 32 Amp fuse)
Nothing else on that circuit causes trips (including a combi boiler, washing machine, dish washer, toaster, kettle, etc. They all work fine, even when multiple appliances are on at the same time.)
When the Kitchen circuit fuse trips, the 13 amp socket switch doesn't blow.
When connecting the the oven to another circuit (eg livingroom sockets - 32 Amp fuse) via an extension, the same thing has happened there too -- trips it after a while.
The oven doesn't always trip, it sometimes works fine, but sometimes trips after working for a while, or if when changing settings or temperature.
From all that info is it obvious to anyone what might be going on? Is it just a faulty appliance, which might have worked without tripping the old consumer unit because it was with ancient fuses (possibly not as sensitive), or is something else going on?
