<p>That's about what to expect from the Psuedo Sine Wave that the
SWs put out. They shortened the list of problem appliances
significantly compared to "mod sine", but its a stepped pyramid
wave. Later inverters (Outback, Magnum) were step waves too, but
just more steps, which translates to less trouble. </p>

<p>I have cured the "washer not running on the SW" once, by adding a
capacitor to the circuit. I can't recommend it 100% from a safety
stand point, but it worked for us. Some body else chime in on the
possible dangers? Cap blowing, fires, shorts? Definitely needs
to be in a metal enclosure.<br>
</p>
<p>I think its either get a different washer or get a different
inverter. At 22+ years, its slowly reaching the time to retire
those old SWs. <br>
