Well according to me front loading are and should be preferred only if there is space constraint. Other than that I have found top loading economical to use and easier to use and maintain in the long run. I may be totally wrong too but based on feedback from users who have front loading as well as top loading, most of them seem to prefer top loading.You did not mention why would you prefer to buy a top loading over a front loading.
Well might be to some extent but I as far as I am aware it needs separate kind of detergents, extra care and maintenance.Front loading cas superb eco savings.
Water requirements and electricity need are far lower.
Sorry to edit : But the main thing I forgot to mention was that incase of top loading you can lift the lid and add clothes or remove the clothes that are being washed. (helps incase of electricity issue or say the machine goes bad or anything), I guess there is no such option in case of front loading machines. Not sure but many have mentioned that once a process starts in front loading then its difficult to stop it till the cycle completes.
Ok good to know. Not sure how it holds the water when you open the door because earlier it was not possible because as soon as you open the door the water would flow out so I guess they might have modified the technology - but cant think how its possible without say draining all the water first and then refilling the water.On present gen. front loaders, you can pause the wash, remove/add clothes to the drum - not a biggie. The cheapest Bosch machine that has been installed at my residence has this option. I believe the others might have it as well. In any case, once you switch off the main power the lock is disengaged and the door can be opened. Switch the power back on and it resumes the wash.
