How to Repair Leaking Cuisinart Coffee Maker

Do you have a Leaking Cuisinart Coffee Maker?  Our programmable Cuisinart coffee maker began to leak water out on the counter top overnight and the pot would come up 2-3 cups short.  I don’t want to buy another coffee maker if I can fix it.  I figured out how to get those security screws out of the bottom cover and fix that leaky hose.  Read along to learn how you can too!

How to Repair a Leaking Cuisinart Coffee Maker

Equipment:

Tools Needed:

Parts (optional, I repaired mine with no parts necessary):

Repair Instructions:

Step 1: Unplug the coffee maker.

We are going to open it up so you definitely do not want it plugged in as you could be shocked.

Step 2: Empty any water out of the tank.

I just turned mine upside down over the sink.

Step 3:  Lay the coffee maker on its back so you can access the screws on the bottom.

We want to remove the bottom plate.  The screws are located in recessed holes located as indicated below.  You do not need to remove any of the rubber feet to access the screws, btw.

Step 4: Remove the 4 bottom screws.

These screws are security Torx-10 headed screws.  This means they are Torx-10 with an additional pin that sticks up in the middle of the screw head.  Here you can see a close-up of the screw head:

The bit tip for these screws looks like this, a torx with a hole in the middle:

Here is what the torx-10 security bit tip looks like

Unfortunately, the hole in the case is too small to use a bit tip like the one pictured above, as it won’t fit deep enough into the narrow-diameter hole.  Lucky for us, you can use a 3mm precision flat-tip screwdriver bit instead, which barely fits down into the corners of the star shape:

I also discovered that you can alternatively use a smaller flat-tip screwdriver bit, which will slip past the security post and sink down into the head.  Once you remove the four screws, you may need to slip a flat-head screwdriver up into the seam to get the bottom out.  Here the lower cover has been removed:

Here is what it looks like inside:

Step 5: Find the coffee maker leak location.

Once you have the bottom cover off you can search for the leak.  I’ve heard of people discovering a leak in the aluminum heating element as well as the rubber tubing.  Quickly I was able to see a light-colored line on the top side of one of the hoses, just above where it connects to the heating element:

With a little pressure on the hose you can definitely see that it is cracked all the way through–definitely the root cause of this leaking Cuisinart coffee maker:

The crack is evident now

Step 6: Remove the wire hose clamp.

Squeeze the hose clamp and push it back on the heating element, as seen below:

Step 7: Remove the heating element end of the cracked hose.

If yours cracked just at the end of the heating element connection you can likely just bend the hose and it will break off.  Alternatively you could cut it off with a carpet knife..

For those of you who want to replace the hose, I measured the heating element pipe at 0.447:

Outer diameter 0.447″

I estimate that the replacement hose should have an ID of 7/16″ = 0.4375 or 11 mm.  I was not able to easily find a replacement hose online.

Step 8: Make room to re-use the old hose.

I didn’t have any 7/16″ ID (inner-diameter) high-temp food grade hose lying around so my first idea for solving my early morning pre-programmed caffeine addiction was to put the old hose back on. I thought about cheating the hose off the other end where it connects to the tank but I don’t know how I would get up in under the tank in order to get it off  and I was pretty concerned about damaging the brittle hose in the process.  The hose is a half-inch shorter now but it seemed like there was enough hose left to get it pushed on there far enough to make it work.  To give the hose a shorter path I decided to cut out some of the webbing inside the coffee pot:

I drilled some holes with my cordless drill and then clipped out the plastic pieces remaining with my wire nippers:

Now there is a straighter path for the hose

Step 9: Reinstall the shorter hose on the heating element and reinstall the hose clamp.

You’ll want to put the hose clamp on first, before reinstalling the hose.  I had to bend the hose clamp closed a bit because it seemed to have opened up in the removal process.  I used some spit on the heating element pipe before attempting to push the hose on.  I was only able to get the hose on about a maximum of 3/8″ on.  WARNING: I would not use any tools to squeeze the hose our you will likely damage what little hose you have left.  Once you have the hose on, position the hose clamp in the middle of the hose as seen below:

Step 10: Reinstall the bottom cover.

I actually didn’t put the screws back into the bottom cover yet as I wanted to test it out for a while and am still shopping for a replacement hose source.  Let me know in the comments if you find a good source where you don’t need to pay half the value of the coffee maker for 10 feet of hose when all I need is about a foot.

And again, you can use a flat-tip screwdriver to reinstall those security torx screws!

The coffee maker is working just fine now so that is nice to be able to breathe life back into what could have been the end of this appliance.

  • Great write up again. Is the caliper pipe fitting measurement 0.474? That’s what the photo looks like, but article says 0.447. Great stuff. Thx.

    • Thanks for checking on me Matt. It is tricky to read a caliper and to help my readers I’ve written a tutorial on it: How to Read a Dial Caliper. My reading is actually correct and let me walk you through how to get there:
      Caliper Reading of Cuisinart Heating Element Pipe One thing to note about this reading is that the needle was actually slightly above 47 thousandths but I rounded it down since it didn’t appear to be half way to 48 thousandths.
