No point in repeating it all but what you say is true. However 3 years after buying an appliance is really too long to return to supplier and complain they will not run on a 13A socket. For all we know the rep may have warned that it would need 16A supply.Let's cut to the chase.
I think 15 A round-three-pin plugs are still legal. Put that on a distribution board with a 15 A semi-enclosed fuse...
My preference would be 16A ceeform as opposed to a 15A BS546.
To add 16a sockets in enough places to allow it to be used would cost several thousand.
Throwing away a grands worth of pressure washers because somebody bought the wrong ones is not a path I'm willing to take
We actually have two of these units, both about three years old, and they've behaved in the same way from new
Would a suitably large Variac or autotransformer be good for the job?One last question - is there any modification that can be made to reduce the power used? Excuse my electronic ignorance - but a "dimmer switch" on the incoming supply, or those power saver plug adapter things that reduce voltage or current? Might that help?
