washing machine problem

Will need pure sine wave, our modified sine wave inverter ran most things but killed our 240v AC fans, they hummed badly and died in about 3 months, pure sine wave no problem

You have no choice but to use a pure sine wave converter for your washing machine and for startup it will use well over 5 Kw for a couple of seconds so an 6 Kw inverter is the minimum , I would propose a dual set of Victron Quattro,s that can handle up to 9 Kw continuesly or a peak of 10 Kw

Bad advice! all inverters have a surge rating that allows them to handle start up loads as its heat that causes them to shutdown a 2000w inverter will probably handle surge loads to 5000w for 30sec's check specs before buying and a electric motor usually draws upto 2.5 times draw on start up but only briefly

Hi!

Almost certainly you have a modified sine wave inverter, not a pure sine wave. And that is the cause of the problem. Almost all washing machines today need sine wave to work -it's due to their electronic programing governors. If you can get one of the old type ( almost impossible) than you would not have that problem.

I also have a Splendide washer/dryer unit. They are very particular as to frequency requirements. The Fisher Panda 12 Mini PMS I have has a pure sinewave out but it went slightly off 60 hz once and the washer stopped working. It needed a small adjustment. OK after that. No harm to the washer. It protects itself against bad supply regulation. And it doesn't like square waves either. I guess they have built in some smarts to avoid bigger problems.
