Re: [RE-wrenches] Front Loader Washing Machines and Modified square wave inverters
Hi again Dana & Wrenches. I heard back from the fellow, along with an updated document about running FP washers on inverters. Hope there's some useful info here. __ Hi Michael, Good to hear from you. The attachment was still essentially correct. I have had the Laundry electronics control guru look at this and he has made few minor updates. I was quizzing him up as to why he had only ± 5% tolerance on the frequency - considering the system rectifies the mains into DC then chops it up again for the motor - and the electronics for the 50Hz 230 V version is essentially the same but without the voltage doubling. He points out that some of the washer range (still) has pumps with shaded pole motors and that on a 50 Hz supply the 60 Hz pumps draw too much current. I.e. the induction is insufficient to limit the current that far from the pump motor's design frequency. I have copied this to Scott Davies. (714.421.8574) He is in our Huntington Beach (Orange County) office. He looks after sales and marketing for North America.

Hi gang. I wanted to add to this that one of FP's engineers is himself a solar bozo. I have not had contact with him in a few years, but way back when, he did send me the enclosed document which outlines FP washer requirements on inverters. Wonder if the models have changed, and how much. I have Bcc'd him, so maybe he will get back to me with the latest info.

[RE-wrenches] Front Loader Washing Machines and Modified square wave inverters
I have a client that just purchased a Fisher Paykel, F-P claim it is inverter friendly and the washer has great specs, runs up to 1000 RPM in the final spin. And it runs pretty fine on a SW4024. Purchased @ a local appliance center, so if it needs repair you are not your own repair person. Cost was $600+ and is ½ of a Staber at $1200 plus freight, which I used to sell. I will probably replace my Staber when it dies with one of these. I did not run a watt hour meter on it but will at some point to get a usage and will report back.

The new Stabers are hard to get to work correctly even on the SW+ inverters. I love my Sears front loader, but I have an Outback. I recommend a top loader or sinewave inverter. I have customers with relatively small systems (under 1000 watts) that are running top loaders (with the simple mechanical dial control, no electronics) on mod sine. They have done fine for years.
