You do need to replace the belt. The one with slack is the one that belongs where you think it looks like it was.

Some front loaders have a door boot drain hole, most do not and it is normal for some water to accumulate at bottom of boot. To help with mold and mildew use a washing machine cleaning solution, follow directions. Also a bleach solution of 2 parts water 1 part bleach sprayed on area helps. If mildew is really bad, nothing will completly remove it. Make sure you use only a high efficiency detergent.

If that is the same color as the rubbber boot or ring that connects the basket with the door then the boot, it's deteriorating, maybe you are using too much detergent, any way the boot needs to be replaced

1. If you have had the windscreen replaced at any time then water can enter through poor re- sealing work at the base of the glass and will find it's way to the floor behind the interior trim panels.

2. Check the rubber seals around the door and around the body work for the door aperture. Water can enter at the bottom of the door and run over the sill scuff plates on to the floor. (Have there been accident repairs to the door?) Also check that the door is sitting correctly in the closed position.

3. Remove the interior trim on the door and check that the plastic liner between the steel door and interior trim is in tact.( It might be advisable to have an experienced person do this for you.) If the liner is loose rather than sealed to the door panel, water build up from inside the door with heavy rain will run past the door trim and on to the floor.

Check the drain holes in the bottom of the doors and make sure that none are blocked or partially blocked up. Otherwise water will build up inside the door panel.

A heavy down pour of rain will test water sealing in any car. I suggest you test for water entry by running a hose for a few minutes over specific areas on the windscreen, on the door glass and around the door perimeter. Have someone sit in the car while you do this to watch for water entry. Test one area at a time and keep water off the area you are not testing as much as possible.

Test 1. The windscreen

Test 2 Run water over the door glass and some will run into the door.

Test 3 Run water around the full perimeter of the door (right on the panel gaps).

no, there should be a plastic trim. u can gently wedge off. u may need to remove part of your door rubber. easily done though.

That black or gray stuff you're talking about is actually a combination of old food particles and soap deposits. The stuff builds up in the corners of the lower front areas of the tub and right under the inside of the door where it closes over the tub front. These areas can develop "scungy" deposits because these are areas that the dishwasher doesn't always clean and/or water remains pooled. A little routine cleaning about once a week around the bottom lip of the door and the door gasket with a damp sponge will prevent this build up. Hope this helps you.
