the 220 volt pressure washer quit...
ground fault unit would not reset at all. Couldn't find anything else wrong. The dang thing is maintenance free, all potted in resin. So, I cut it loose and got the washer running. No sign of trouble now.
How do I find the fault, or determine the ground fault unit itself failed? We often wash on wet concrete. The better half does most of the washing and its considered bad form to electrocute your honey.
