KitchenAid Proline coffee maker has what looks like corrosion (bubbling of the finish) near where you fill the water reservoir. Any fix for this or to keep it from spreading?

Leaking water from bottom of unit during brewing:

• Verify that the water is leaking from the bottom of the coffee maker and not just running down the back during filling and pooling underneath. (Look under coffee maker - without lifting - to see if water droplets are hanging from bottom of unit)

Resolution:

If verified that water is leaking from bottom of coffee maker Contact Us for further assistance.

Just like any coffee or espresso maker, descaling is a process that needs to be done periodically. If your location has hard water, you may need to descale more often than elsewhere, but it's nothing to worry about. It's just a chemical process that occurs as the result of mineral deposits from the water collecting on the elements inside the coffee maker. I'm sure that coffee manufacturers will sell you tablets for descaling, but I've always just used undiluted white vinegar as the reactant. To do this, I recommend: 1. Empty all of the water from the reservoir. 2. Fill with undiluted white vinegar. 3. For this type of coffee maker, brew as many cups as it takes to empty the reservoir, being sure to dump each cup in the sink as it finishes. 4. Once you've run through all of the vinegar from the reservoir, refill with water and run a few cycles to rinse. (You may want to leave the water to soak for a while to give the residual vinegar further time to clean off the minerals.) 5. Fill again with water and rinse. 6. Once you've emptied the reservoir a second time with the water, your machine should be adequately descaled and ready to brew coffee again!

With the coffee maker unplugged and an empty cup in place, I filled the reservoir with filtered water and with a short length of flexible plastic tubing I blew in to the small hole in the bottom of the reservoir. I did this 4 or 5 times sucking some water in to the tube to force it through the system. When I had finished there were a lot of grounds in the cup and the next time I used the coffee maker it worked perfectly.

So I had this same problem the fix was pretty simple. Air had gotten into the fill line and the pump couldn't pump the air filled line. So to get rid of the air try to brew a cup of coffee (make sure you have a cup under) now cover the over flow at the top of your water reservoir with your finger or thumb. Air bubbles should blow into you water storage tank. Once the bubbles are gone remove your thumb or finger. Now try to brew a cup of coffee again.

Descaling removes the deposits left behind from hard water. These mineral deposits will slow heat transfer if not removed from the heating element. To descale the coffee maker, use 48 oz of undiluted vinegar (household strength) and have a large ceramic mug to hold the output. Empty any water in the reservoir. Pour vinegar into the Water Reservoir and fill to the top of edge of the clear viewing area. Place a mug in the drip tray and press the Large Cup Button. (Do not use a K-cup.) When the brew cycle finishes, pour the contents of the mug into the sink.

Repeat the brew cycle until the reservoir is empty. Open and close the lid between cycles. When the reservoir empty, fill with water and let the coffee maker stand for 4 hours with the unit ON. After four hours, rinse the coffee maker by doing several brewing cycles (again without a K-cup). Discard the liquid after each brew cycle and repeat until the reservoir is empty.

You may need to perform additional brew cycles if you notice a residual taste.

I hope this helps.

There is a quick and inexpensive solution to the problem. Household vinegar. Pour about one cup vinegar into water reservoir, replace filter basket without filter allow it to cycle through. After it has finished brewing, you may repeat with another cup of vinegar. Once you are finished running the cycle with vinegar, fill water reservoir with water and cycle through. Be sure to run water through machine at least twice to rinse out all the sediment and or vinegar. Works everytime my coffee maker starts running slow.

Believe it or not, vinegar is a blessing for cleaning nearly anything out of your coffee maker.

Fill your water reservoir 1/4th full with vinegar, then fill it the rest of the way up with water.

Run the coffee maker, then let it sit for about 10 minutes. Pour the mixture back in to the reservoir and run it again. Let it sit another 10 minutes.

Dump the mixture and use plain water this time. Let it sit for another 10 minutes. Dump the water, then repeat with clean plain water.

Wash the filter basket and pot with hot soapy water. If the vinegar smell is still present, just run it again with plain clean water.

You might try this first. Remove the entire top lid and remove the clear suction cup located near the back of the brewer. Clean this cup with white vinegar and also take your deliming tool and place it in the hole where the suction cup was and clean out. If this does not correct the problem, please call customer service with the model and code date. If your machine is 3 years old or less, we can replace it at no cost. If it is over 3 years old, we will replace it at a reduced price.
