There
are a few problems that can occur with the diswasher door assembly.
These usually involve the latching mechanism, the door seal, the
counterbalance spring assembly or the hinges.
1)
The door latch plate can occasionally become out of alignment. Some
door latch plates are adjustable, some aren't. If yours is adjustable,
try loosening the retaining screws and repositioning the plate.
It's trial-and-error, so have a lot of patience. If this doesn't
work, then the latch needs replacing.
2)
A new dishwasher or a newly installed door seal can be difficult
to close for a while until the seal softens and compresses over
time. You can try adjusting the latch, if possible.
3)
If the door feels unusually heavy, there could be a problem with
the counterbalance spring assembly. These counterbalance assemblies
allow the door to open and close easier and are held by two springs.
On some dishwasher models, holes are positioned in line so you can
re-tension the springs by moving the spring hooks to other tensioning
holes. If any of these springs break, they will need to be replaced
as a pair.
4) The door hinges might be bent. They can seldom be adequately
fixed and should be replaced.
