Hose connection to sink won't stay on - GE Nautilus 24" Built-in Dishwasher

Plumbing codes vary in different locations. Some require the dishwasher hose to be connected to an air gap vacuum breaker mounted above the flood level rim of the sink. At the very least the hose should be run up as high as possible under the sink before connecting to the garbage disposer. To keep waste water from backing up into dishwasher.

Hope this helps.

If the dishwasher is connected to a spigot on the waste under the sink, check that the end has been cut off the spigot (on the plumbing not the machine hose) or that end stoppers have been removed. Also, check the hose has not been crushed when installed.

Your dishwasher drains into the garbage disposal. It you tried to use a plunger to clear your clogged sink or run the disposal with to much junk in it you may have force debris into the dishwasher drain hose. With both the dishwasher and garbage disposal disconnect from power disconnect the dishwasher drain hose from the garbage disposal. This is usually about a one inch black hose. Clear out any debris in the hose and inlet nipple on the garbage disposal. If debris is compacted far down the hose it will need to be disconnected from the dishwasher end and remove to clear the blockage.

Good luck!

Has no hose weight or not heavy enough weight on hose under sink. either buy a weight and install on hose about 18" from the bottom of sink. or you can use a 3 ounce fishing sinker with bread tie and tie it around hose aprroximately 18" from bottom of sink. It needs the weight to keep the faucet head in.

Run your garbage disposal and sink water for a few minutes in case there is anything clogging the drain. Also look under your sink in case the drain hose is kinked. That hose might also be clogged but is a difficult job - maybe pro help is needed if you are not comfortable doing it yourself. Last option is that the pump is bad and must be replaced

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.

The most common cause of this is a restriction in the drain. It can be in the hose where it connects to the dishwasher, but most often it is where the drain hose connects to the kitchen sink. Remove the hose from the sink and make sure the hose and the sink connection are clear.

Make sure that there is a weighted ball connected about halfway down the retracting hose. If not you need to go to a supply house and purchase one and its a simple install.However if there is one attached you can loosen the 2 screws and slide it up closer to faucett but not so far that you can't pull out the sprayer as far as you need. Also make sure nothing is obstructing it under the sink. bottles, cleaners, etc.

Did you have a dishwasher before? If so, you must have had a sink tail piece with a dishwasher drain coming off the side. For the connection, you may have to get an adapter to fit the end of the dishwasher drain hose to the sink tail piece. Take all pieces to hardware store if necessary to get an adapter which fits. After you connect the drain hose, make sure that the drain hose has a "high loop", meaning that the hose curls up at least 6 inches above the connection point before it goes down again. This is important to keep sink waste from getting back into the diswasher hose if the sink drain backs up.

Remove drain hose from where it connects to the plumbing under the sink/tub. Inspect the spigot. If clogged, clean. If clean, then tilt machine back and remove drum to pump hose from pump. Check hose and also drain pump. Clear any obstructions.
