How do I get water to drain from my dishwasher
test this steps and fix it.God bless you
On some dishwashers that have a filter (screen) along the back wall of
the tub have a piston valve. The piston valve commonly causes
dishwashers not to pump out. if your dishwasher does have a filter,
remove it. Now remove the piston valve located in the center behind the
filter. Now to check the piston valve, press up on the spring. Once done
the piston should stop up the hole in the top of the valve. When a
piston valve, is bad the piston dissolves to the point that it can no
longer stop up the hole, in this case replace it.
Another common problem on some dishwashers that will cause it not to
drain properly is the drain solenoid. To check this, first disconnect
power from dishwasher then remove the bottom panel of dishwasher. Once
off, you should see the drain solenoid attached to the main pump then
reach under the dishwasher and push down on the solenoid. If it will not
move down it is bad and needs replacing. If it will push, down most of
the time it is good but not always so follow these steps as well.
Reconnect power to dishwasher, now start the dishwasher in to a cycle.
If you have a mechanical timer turn it slowly until the solenoid
energizes. If you turn the timer all the way around and the solenoid
never energizes replace the solenoid. If you have an electronic control,
start the dishwasher and wait a few minutes then push start/reset then
the drain solenoid should energizes, if not replace the solenoid. At
times the timer will cause this part to go bad especially if its melted
or frozen down. So you may have to replace the timer as well.
If your dishwasher is not draining properly, the check valve may be your
problem. The check valve will be on some dishwashers with both a
separate drain pump (note if you do not have both you will not have a check valve). The
check valve will be located where the black hose connects to the drain
pump. To access the check valve, you must first remove the water from
the dishwasher. A Wet-Vac works well. After the water is out, disconnect
power to dishwasher. Now remove the dishwasher from under the cabinet.
Now remove the black hose (even though you removed the water you will
still have water in the pump so be ready).Once off you should see the
check valve. It's the little red rubber flap. If it is torn off, the
flap may have gone down the drain but you still should see the red ring
left behind, in this case replace the valve. Sometimes the check valve
will swell up and hang in the pump, if so replace it.
If your dishwasher is not draining properly, the drain pump may be your
problem. As stated before, not all dishwashers will have a drain pump.
To check this, First check to see if it is getting power. You should
have 120 volts when the dishwasher is put into a drain cycle. If you
have power and the pump does not run remove the pump and check for
obstructions if none found replace the pump.
If your dishwasher is not draining properly, the drain hose may be
stopped up. To check, remove all the water from tub. A Wet-Vac works
well for this. After the water is gone remove the drain hose (even
though you removed the water you will still have water in the pump so be
ready) from the house plumbing and the dishwasher. Check for
obstructions and remove. If you just installed a new garbage disposal
check that the metal knockout was removed. . Check the air gap if this is not right your dishwasher will siphon water back into it.
