Hi,
Here is a tip that I wrote that will help you with your dishwasher not drainingproblem...

Dishwasher Problems - Waterwill not drain out

heatman101

Hi, this could be a bad control board or a bad motor. It uses the same motor to wash as to drain. It just changes the direction of the motor in order to switch from drain to wash.
You'll need to run a cycle and you will need a multimeter to check which one needs to be replaced. Remove the kick panel and check the grey wire to the ground wire when it should be washing. If you have 120 volts, you need to order and replace your control board. Otherwise, if you don't have power and it's still draining, you need to order and replace the motor.

Hello,

Welcome to FixYa.

Based on your post, the good news...I can fairly confidently tell you It is likely nothing very serious, but the "resolve" requires some investigation on your part.

What the pump running continuous means is the timer has indicated a overfill.

**before proceeding turn the dishwasher power off via the home breaker panel, or unplug it from the wall if that is possible...most are hard wired to the home electrical...safety first**

The first thing to do is remove the toe panel/kick plate and inspect the base for water. There will likely be water present.

With the aid of a sponge, towels, or a wet-dry shop vacuum, absorb the water from the base, that should restore normal operation...it should be known that if you leave the unit for a few days, the water in the base will evaporate hence appearing as everything is fine again...if any other problem/leak does exist it will return.

If the unit works fine after resetting the power/breaker and soaking up any water present, it can likely be chalked up to a drain back-up or obstruction in the drain hose or pump... (it could mean a faulty drain pump so you'll need to pay close attention the next few times you run it)

**The float is primarily the last ditch safety to prevent disaster in the event of a overflow, back-flow, or leak underneath the unit and the continuous pumping is letting you know to service or call for service to the unit**

Hope this helps move you forward, or even better resolves the issue altogether. Let me know of course, I will help you move further if necessary.

Good luck.

you will need to replace the entire soap disp. You can find it at marcone.com w/ your model #

You may have it set to an ECO wash (economy)witch may exclude drying cycle at the end to save power.

The draining cycle remaining on is an indication that the anti flood sysyem (polystireen float / micro switch) at the bottom has been activated via a water leak. This anti flood system puts the pump motor on and shuts the inlet water. Dry the water at the base / find the leak or blocked pipe causing the water and this should rectify your problem.

Check the following to address this issue.


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).

I have the same thing, unit pump keeps running, when I pulled it from under the cabinet, if you tilt it back a little it stops, as soon as you lower it back down the pump starts to run again. Getting code as too much water in the tank even though it is empty. PLEASE HELP!!!!!

Since this was posted in May I guess it's been fixed but for those of you seeing this problem for the first time, here's one reply:

This sounds exactly like the problem I just found with my DFUD042. There is a small black hose between the base of the tub and a pump motor - part number on the hose is 8072888. The hose has a small **** or crack in it and water is leaking which is most likely the problem causing the symptoms. I had to throw the circuit breaker to get mine to shut off as well.

When I tried to remove the plate it was stuck under the black sound proofing so I had to work around it a bit until it finally came off. Now I just have to find the hose and some clamps.
