Hi - I had a dishwasher that blew it's fuse every time I plugged in it (blowing both the fuse in the plug and tripping the circuit). I decided to replace the dishwasher believing it was faulty. Having used the new one OK for a month, I now have the same issue!
Do you know how to safely isolate the plug socket that the dishwasher plugs into?
If you do I would ISOLATE the circuit at the consumer unit (=fuse board) and remove the front of the socket that the dishwasher plugs into. Check for moisture, loose connections or signs of darkening or blackening.
Beyond that it's a case of getting a guy out to test. Water and electricity close together can be a recipe for problems.
Are the dishwasher and washing machine sharing the same double socket? This can be a cause of overheating and melting in the back of the socket unit. A lot of double sockets are only rated for max 20A. If dishwasher and washing machine were both running on their heat cycles at the same time it could draw nearer 26amps. (2x13A) If the original fuse in the dishwasher blew then the old washer could have had a serious overload fault that may have damaged the internals of the socket assembly. Is the new dishwasher just tripping the fuse box but leaving the plug fuse intact? preferable I would put both washing machine and dishwasher on separate single sockets. Or at least replace the existing socket front to eliminate it from the problem. If it is an RCD tripping (not and MCB) it may be just a blockage in the outlet pipe, does the fault happen during the running cycle or just during the drain cycle?
