Hi,
Follow the below guide :-
Drain line/air gap
A
clog in the drain line or air gap (if there is one) is the usual reason
that a dishwasher won't drain. Often the problem is at the point where
the drain line attaches to the garbage disposer or household drain
line. If you remove this line, you can clear any debris from the hose
or hose connection. Be sure to reattach the hose before starting the
dishwasher again.
Pump
Your
dishwasher pump ejects the water. The pump is usually mounted directly
to the motor, then attached to the bottom of the dishwasher. You can
reach the pump from inside the dishwasher, but first you need to remove
the lower rack, the spray arm, and the spray arm support.
Look
for an impeller--a round plastic fan blade-type of device that spins
around. This is the wash impeller, which forces the water through the
spray arm. Beneath the wash impeller is the drain impeller, which is
similar in size and shape to the wash impeller. The drain impeller
pushes the water toward the drain port. These components make up the
pump. If any of the pump components are defective, you need to replace
them.
Drain valve and/or solenoid
Many
dishwashers use a drain valve with an electric solenoid. When
electricity flows to the solenoid, the valve opens and diverts the
water to the drain. Sometimes the solenoid, or the diverting lever,
sticks and prevents the dishwasher from draining or filling properly.
Try to free up the solenoid to lubricate the lever. Otherwise, you may
have to replace the solenoid or pump assembly. With these systems, the
motor always rotates in one direction. When it's energized, the drain
valve diverts the water.
Other dishwashers simply reverse the
direction of the motor to drain the dishwasher. These units don't have
a drain valve. Instead, there's a drain hose connected directly to the
pump housing.
Belt
One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.
Motor
If
the motor isn't turning or working, the unit won't drain. First check
to be sure you have power to the dishwasher. If not, see the section
"It doesn't work at all." If the motor hums but doesn't turn, it may
need to be replaced.
Some dishwashers are susceptible to
getting stuck if you don't run them regularly. If you haven't run the
dishwasher for more than a week, you may need to manually spin the
motor to free it up. If the motor is defective, you need to replace it.
Dishwasher motors can't be serviced.
Timer
Part
of what the timer does is control the motor and drain valve. If the
timer doesn't work properly, the water may not drain and you need to
replace the timer. This problem is uncommon.
Let me know, if need further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
Two things to consider....clean water or
dirty water?
Clean water usually indicates the fill valve
is not shutting off all the way and the fill valve is "weeping" water
in all the time = new fill valve time!!
Dirty water usually is not a dishwasher
problem but more of a plumbing issue. Often the sink drain that carries the
sinks water outside is not fast enough and some of this sink water is backing
up into the drain hose and filling up the dishwasher through the drain hose.
The drain from the sink to outside needs attention as this type of a problem
indicates a slow house drain for that sink.
The dishwasher drain line should be clamped to the top underneath part of the counter before entering the sink drain plumbing, this may help the water from coming back inside the dishwasher.
