I don't know whether to recommend a repair on your current washer, but I can give you my thoughts and experience with front-loaders.
Yes, they do save on energy and water...... But not TIME...
Look into how long it takes to complete a regular cycle, add in an extra rinse.... (which I feel is necessary) and
With your large family, would you be able to keep up with the laundry with that kind of time-frame???? Two hours per load to wash and dry....
Laundry might always be a sunup to bedtime thing.
Now, I love the performance of the front loaders...
I have brand new Bosch (got rid of our Duet Sport as the washer was LOUD with the lame water-pump that Whirlpool had put on them)
Things I like.... The performance... I have not used Spray-N-Wash since I got frontloaders.... (I do actually sometimes add more water thru the detergent dispenser, as I do not feel that they wash and rinse thouroughly enough with heavy and heavily soiled loads... Might be important with three sons! I like to actually see some water and suds in the bottom of the drum/tub!
I loved the controls on the Whirlpool - you could select everything... water temp, spin speed, etc... On my new Bosch, you just put it on one of the pre-programmed settings... the 'QuickWash' will get a load done, with an extra rinse (which is necessary) in an hour... But, I found out that it only uses COLD water!

Can't convice me that cold gets fabrics, especially whites, as clean as warm!
If you get a front-loader, get used to using a TINY amount of HE Detergent. (extra rinse, as just mentioned above)
What I do like about the Bosch, is that it is the only model that has a full, stainless, dryer drum. As opposed to the ceramicoat that only the sides of the drum turn while the back and front panels remain stationary. On my Whirlpools, the constant friction created with the tumbling clothes and the stationary panels resulted in wear on the finish... after a couple of years you could see the wear, and now it is down to the primer.
When we bought our new set, the salesman did say to avoid Electrolux. I am assuming he had plenty of reason/experience for such a strong admonition. I would also avoid GE or Maytag.
I would also have considered an LG... Sears are now made my LG. (Used to be Whirlpool.... Changed to LG just a while back.)
Hope this helps!
