Is it normal to have water left in front loading washing machine after the cycle?
First, make sure you don't have a clogged lint filter. On the bottom of the front side, is there a small door where the lint clean out is?

Then, check the drain pipe itself to make sure it's not clogged. Is any water leaving the machine?

Otherwise, sounds like you have a broken or clogged drain valve. This isn't a basic diy project and would involve taking the machine apart. I'd suggest you call a home applicance technician.
