Washer troubles [RE-wrenches]

Nick,
That is kind of a twist, isn't it? The problems could easily be 
voltage or frequency, but not too likely waveform from a genny. I've 
seen all manner of grief over the years from generators, especially 
when folks are using only one leg of a 120/240V machine. That makes 
some of the generator voltage regulation schemes go bonkers. A far 
better scenario would be to run both legs through a step down 
transformer. Most DIYs also don't know that Inverter/Chargers are FAR 
less efficient in the charger mode. The older mod. square waves are 
around 50%, so you end up using far more input power than you might 
think going to the charger. That could cause a low voltage or 
frequency problem. Another possibility might be phase angle. If the 
washer is turned on and running when the genny is started or stopped, 
there is a phase angle shift that often occurs when the internal 
transfer switch clicks over. That shouldn't happen with the SW, but 
it will with most others. Obviously, the safest practice would be to 
have NOTHING running when starting or stopping, but that's hardly 
real world. With a manually started appliance like a washer, however, 
your client could easily learn to make it SOP if the problem is 
determined to happen during the transfer.
Good Luck, bob-O
