You should post this on the Laundry Forum, which is dedicated to washers/dryers, etc. I think you've gotten your money's worth, and should replace it with stacked front loaders. They're more efficient, and gentler to your clothes too. Also, if you repair and keep your current washer/dryer, Murphy's Law says it'll break again when you most need it (like holidays), or worse, spring a leak or something like that. Here is a link that might be useful: Gardenweb's Laundry Forum

plumbly22, 1000kwh/month drop? Wow! That's the equivalent of running an electric dryer 8 hrs/day, every day of the month. For those estimates, I assume you must be doing a lot of laundry and heating water with electricity? Possibly a lot of hot loads, maybe even warm rinses?, and heated with electricity? I'm still not sure I can total 1000 kwh. It's definitely difficult to draw conclusions, and I can't compare, since your stated difference from the appliance change is 2-plus to 4 times my total electric use, and I have an electric dryer, 30 year old topload washer, electric stove, etc. Actually, water savings should be far easier to calculate than electric. Take the amount of the top load and subtract the amount of water in the frontload, and include all extra rinses, not just the wash amount. Probably about 20 gallons per load difference? (I have no idea.) Then multiply that by the number of loads you use. Then times the gallon rate for water.

The main drive motor on these machines is quite robust and unlikely to be the problem. The separate pump, however, IS probably the problem. A leaking pump that's not fixed ASAP will often/usually short-out and zap the controller board. The pump is not overly expensive (~$70), but the controller board adds ~$125+ to the repair. Someone posting in another thread here had success replacing a blown fuse on his controller board, but that requires soldering skill to remove and replace the fuse and "luck" that nothing else is wrong with the board. It's also possible that one of the water valves or the water mixing chamber inside the console leaked which shorted the controller. You'd have to investigate to determine what exactly is the problem. Parts are available at SearsPartsDirect.com or FisherPaykelParts.net (Sears is usually lower prices, but not always on all items).

You should ask this question at www.automaticwasher.org. Those guys collect and restore antique washers and dryers. They will be able to advise you whether or not is is worth repairing or replacing your set. They are very knowledgeable.
