Re: our dishwasher was gushing water after a cycle
If you dish washer pumped or drained water up into you sink then you drain line from the sink or even further down is clugged up, Machine out drain line. A drip sized cable machine can be rented. I recomend a 1/4 inch line. You will only have to go frim the sink to the main line.

First check out your model to see if it has a built in garbage disposal, if so, make sure it is not mucked up.
Run hot water down your sink drain while running the sinks garbage disposal. Pour baking soda down your sink garbage disposal followed by white vinegar. Let it sit and foam. Run hot water down sink disposer while running. When finished:
Run empty dishwasher with no soap, let dishwasher fill with hot water to wash and then pour 1 cup of white vinegar into the bottom and resume wash. Make sure you take it through the dry cycle. When finished, open dishwasher and let it air for a couple of hours, longer if you live in humid area. Hope these steps do the trick.
As far as draining the backed up water you may have to run a short cycle wash to help it. In California homes we have a by-pass vent which runs from the dishwasher drain hose up to a port in the kitchen sink. From there it is attached to the side port of a garbage disposer. In the event of a backwash the by-pass vent is high enough that it can't reach a level that wiould flow back into the dishwasher.
If water does not drain at all then the drain pump could be blocked. If only a little water is remaining but cycle is complete, then this is normal. However, do check the kitchen drain is clear and you do not have a garbage disposer (insinkerator) in sink which is full. Normally empty it before you start the dishwasher. Do you get any alarms (lights flashing etc)
The problem may be in one of several places, here's a list of things to try, starting with the easiest and progressing to more difficult:
1. Run your hand around the bottom of the pool in the dishwasher looking for paper or cellophane that may be covering the screen of the drain.
2. Disconnect the drain hose from under the sink (get a bucket and rags) looking for a clog at that point of connection. Run the dishwasher drain cycle while you have this hose pointed into a bucket - if nothing comes out, the problem is between points 1 and 2.
3. Partially remove the dishwasher so you can get to the drain hose where it connects to the dishwasher. Temporarily put another drain hose on it, with the other end in a bucket. Run the drain cycle of the dishwasher. If it comes gushing out, the drain hose is clogged. If it still won't drain, your will need some disassembly of the drain & pump.
If there is a lot of water sitting inside the applicance, it's possible that the high water float switch has been activated and is preventing the dishwasher from running. Open the door, remove the bottom rack, dip as much water out of the bottom as possible with a shallow ladle or even tupperware container. When that is accomplished, shut the door and try to run a drain cycle. If the unit won't start, you may have to remove more water. You don't have to have the rack in place to run the drain cycle.
Theres a drain pump located at the bottom of the unit if you follow the hose from the pump then to the drain if your unit isnt draining you might have to call for service from a technician to have them change your drain pump. If the water is just sitting inside the unit and when u start the unit it should fill with water again.Also if you have a cancel function by pressing this you will make the unit drain if you dont hear anything when u press the cancel button you definetly need a pump
I just had this problem with a zanussi dishwasher - I opened it this afternoon to find the bottom full of water - luckily not deep enough to flood my kitchen when I opened the door. I determined that the sink drain was clear (ran water, could hear it going down the drain outside), so the problem had to be in the dishwasher or drain hose. I poured just a little mr muscle sink & plughole unblocker in the bottom of the machine where the trap is, left it about 30 mins as per instructions, followed by a little boiled water - no difference. Scooped out the water, removed the filter (the big round bit, not just the trap that you pull out and empty) and scooped out till I could see what appears to be the out pipe. Thought what the heck and ran a rinse cycle - no dishes, no detergent and lower tray and arm thing removed for convenience. Water drained just fine, ran a second rinse cycle which got rid of the suds from the plughole unblocker. I now have an extremely clean and sparkling dishwasher and am about to run a load of dishes through it.
I hope that my post is helpful to you, I don't know if all the steps are necessary, it may have been a freak occurrence that would have gone away with a simple rinse cycle. It may of course be a problem with the pump on yours, I was hoping that wasn't the case on mine, and I had lots of old towels on hand in case water came out when I opened the door. But it's possible your machine has the same problem as mine and that this info works for you, I hope that is the case.
Are you sure your drain system is not clogged or restricting water flow ? When you say youtook off the hose off under the sink and it seemed to be lots of water running on the rise cycle .. that suggests that you may have a restriction after the drain hose in your house drain system. ... Some other considerations.. To minimize the possibility of electric shock, unplug this appliance from the power supply before attempting any maintenance.
Some water, usually one to two cups, remaining in the bottom of the tub is normal. However, if water is covering the bottom of the tub, the dishwasher is not draining properly.
Check for paper or large objects covering or blocking the sump area in the rear of the tub.
Make sure that the right type and amount of detergent is used: Using the wrong type or too much detergent can cause sudsing that can prevent the dishwasher from draining. Only detergent specifically designed for automatic dishwashers such as Electrasol®, Cascade® or Cascade Complete® should be used
how is the water flow at your sink this is a portable right un screw the connector at the sinkand check the screen 2 your fill hose could be kinking up when you pull it out take a light and look down into the washer see if you can see it kinked we will go from there
