JP-24 built-in won't drain

Hi, if the water doesn't drain from your dishwasher, check the drain line and pump..

A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.
Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

I would check for obstruction in the drain hose.Take the drain hose off the garbage disposer hold it as low as you can over a pan or bucket and see if the dishwasher will drain centrifugally.If it does I would assume the pump is bad or disconnected.Possibly a utensil jamming it.

On the whole dishwashers are simple devices.
A controller tells a pump what to do - push water around the machine or push water into the drain.
Miele machines have a very good record for lasting over 20 years.
If you are a "handy person" you could try checking the hose to the drain is clear - blocked hose won't drain.
Have you checked the filter system inside the machine - at the bottom of the d/washer under the bottom spinning arm? If this is blocked - no drain - so clean it well.
If little checks like this are all OK well its up to you - repairs could cost £60 - £80 a new Miele would be nearer £400.
Try to get it fixed its kinder to the planet - and your pocket.
Good Luck.

Uncouple the drain hose connection under the sink and use a wet/dry vacuum to **** out the drain hose and the stub on the sink drain plumbing to clear any possible clogs. There may be a blocked check valve near the pump that might have to be cleaned or replaced. Check the hose itself for any kinks or collapsed section. There might be a damaged drain impeller on the pump. Hope this helps!

you may have an inefficient or partially blocked water pump remove drain hose and check if there is an obstruction if so clear it and re attach hose try draining machine listen to water flow if strong ok if not you still have an obstruction or faulty pump if no flow at all pump or control failed on final drain hope this assist you

I had similar problem and rerouted the drain hose like papps54 said. I still had the condition and decided to pull out the drain hose completely to see if there was any debris trapped inside the hose. There was! I removed the hose from the machine completely, cleared out the debris, and let the hose soak in white vinegar overnight. In the meantime, I looked back up the drain outlet and found evidence of debris lodged in there as well. I didn't completely dismantle the dishwasher at this point but I did eventually clear it out as well as the drain filter located inside the dishwasher. After reassembling the drain hose and dishwasher, I cleaned it with baking soda for three nights and now it runs very well with no odors. Runs quieter as well.

Look for a kinked drain hose. Make sure drain hose is not plugged. Remove drain hose from washer and inspect drain outlet on washer is not plugged. Stick your finger inside and feel for any clothing fabric ect blocking drain line. The washer may have a built-in screen that is plugged. You may need to remove the back cover of the washer and inspect drain hoses for any kinks or blockages.

Check drain hose first.

If you do not find any blockage, then you will need to access the pump, remove pump hose and look for blockage in there.

If there is no blockage at all, then either the water level switch, a faulty pump, a wiring problem, or a faulty timer board can be cause the machine not draining.

depending on the age of this unit it may have food blocking what is called the "check valve".
on most models it is mounted right on the outlet of the pump housing. one model uses a 4 inch plastic tube style device and is about 1/2 inch on the pump and 1" on the hose. inside of it is where the food items can block the check valve. remove the hose and unscrew the check valve from the pump and see if something is blocking it.
on newer units the check valve is built into the drain hose, if you hose has a 90 degree elbow molded into it where the hose hooks up to the drain pump. once again take the hose off and look inside the hose or try to blow through the hose and see if the hose is clear.
good luck tom
