I have a 15 gallon tank with a filter that came with it, it has worked fine for over a year and around 4am a couple of nights ago I was randomly awoken and heard a very loud electricity/sparking sort of noise. When I went to investigate I found that my filter was no longer working. Have replaced the fuse to no avail, and have took it out to check it over to see if there is any obvious damage to the motor and nothing. Does anybody know what could be causing this not to work? Also the plug sockets do work as it is an extension board with the heater and light on which work fine, have tried rearranging the plugs to see if its a problem with the specific part where it was plugged in and other appliances have no problem receiving power from them.
