We've recently been having a fishy smell when we use the washing machine and tumble dryer (at the same time usually, so we weren't sure which it was). Then the washing machine plug stopped working; we started using a different plug, and the smell stopped.
This reminded me that a fishy smell can = an electrical problem (from MN). Google has confirmed this, and has said that it can be really serious.
Is there anything that I can do now? Obviously I want to get a qualified electrician round ASAP, but that is likely to be Monday at the earliest.
