If at least one part of the drain hose is not at least 19 inches off of the ground the dishwasher will not drain properly. I would actually put a loop in the drain hose if possible. This will help with draining.
Hi. I can help you. There is a plastic knock out in the garbage disposal which you must remove with a small chisel and a hammer. This is there for those installations where there is a disposal but no dishwasher.
If you did not remove the plug from the disposer drain where you made your drain connection will cause the dishwasher not to drain. This should have been mentioned in your installation instructions. Also, routing the drain hose other than what is specified in the instructions, will allow food waste to enter the dishwasher when you grind food in the disposer. Read your instructions and don't take shortcuts, you want to have your appliances work well for a long time, as you have made a considerable investment in some quality appliances.
Hope this helps!
The pump is a motor which runs in one direction to spray water in the dishwasher to clean and the opposite direction to drain the water. The problem could be from a clog or kink in the drain hose. Several years ago the drain line would connect to the sink garbage disposal. If the garbage disposal is not draining or the dishwasher connection to the garbage disposal is restricted or clogged the dishwasher will not drain. Under the sink, look at the garbage disposal to see if a rubber hose is connected at the side of the disposal unit. If a hose is connected to the side of the disposal, remove the hose clamp and check for any restrictions from garbage in the inlet or hose. You can use a screwdriver to clean the fitting to the garbage disposal and a wire hanger to free any restrictions in the hose. If the dishwasher does not connect to the garbage disposal it should connect to the sink trap. This is more common with new dishwashers because they have built-in disposals. Disconnect the drain hose from the sink trap and the dishwasher and look for a clog at the sink connection. The dishwasher inlet should have an angled piece of plastic or metal facing downward to prevent the waste from the dishwasher from spraying up into the sink. Do not get to aggressive with the cleaning in order to prevent breaking the angled piece of plastic or metal. Look for any kinks in the hose and try to run water through the hose, but do not use the sink which you removed the drain line from or it could leak under the cabinet. If you see a bad kink replace the hose with a new one. I hope this works and you find the problem without a great deal of time or trouble.
