Won't drain, water comes out on the floor during the final cycle
CHECK THE FOLLOWING--
1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to
see if it is clogged. Unscrew the top cap and see if there is anything
blocking inside. Note: If there is no air gap installed, the dishwasher
might not drain properly.
If the drain hose is clogged, the dishwasher would not drain. If there
is an air gap installed, it is very common that a hose going from the
air gap into the garbage disposer is clogged. Remove and clean the
hose. Make sure to reattach the hose before starting the dishwasher.
Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.
2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.
Note: Sometimes the belt would just come off the pump. Even though it
might not be broken, it is recommended that you replace the belt,
because it is probably too stretched out.
3. Pump
Some models have two impellers inside the pump - one, wash impeller,
takes care of the wash cycles, the other, drain impeller, drains the
water out. If the drain impeller is broken (broken blades, shaft), the
dishwasher would not drain. Replace any broken pump components.
4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to
drain water out. Sometimes the solenoid gets stuck, preventing the
water from draining out. Try to free up the solenoid. If unsuccessful,
you might have to replace the pump assembly.
5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.
Replace the motor if defective.
6. Timer
Replace if defective (note: uncommon problem).
It is
possible that the machine does not start off the cycle because there are errors
due to feedback from the inputs. For the program to start up the main program
controller must initiate the INLET/MOTOR/DRAIN
pump/ valve to open up and allow each function to be driven starting from
the flow of water into the drum as also the drain valve to open to exit the
water at the point of the program cycle. If this does not happen then the
voltage at the valve/motor/pump must be checked or the fault relates to no
voltage from the controller. This means
the controller is a suspect.
If the
water flows though the inlet then the flow pressure should be good, if not the
inlet valve is bad or there is dirt in the filter. Also check the flow at the
inlet of the water line. Once the water comes into the system the WATER LEVEL
SENSOR - normally a pressure switch- must activate at the preset/chosen level
to give the signal to the program controller to switch on the motor. What is
most important for the motor to start functioning is that the door switch must
be ON when the door is shut or this will be an error for starting the motor for
rinse and wash.
Check this
link to replace the inlet valve:
Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the dry spin with the drain valve/pump activated so as to drain off all the water from the clothes during the spin.
