How to Repair a Mr. Coffee Rubber Tube

By James T Wood

Mr. Coffee coffee makers use a hot-water drip system to extract the coffee from the coffee grounds. After you pour the grounds of your favorite coffee into the basket and flip the coffee maker on, the water gets heated separately in a container that's connected to a spray head above the coffee basket. That heated water needs a reliable a way to reach your coffee, though, and that's what the rubber tube is for. The water travels up the tube to the spray head and then falls down on the coffee grounds, which then drips through the filter and into the decanter as the coffee you drink. If the tube becomes cracked or damaged, your Mr. Coffee won't work. This is not a typical rubber tube, though, since it must withstand boiling water temperatures that would melt normal rubber. The bad news: Mr. Coffee does not offer replacement tubes to the public. The good news: You can repair the tube yourself, and still have your coffee in the morning.

Get your Mr. Coffee brewing again by replacing the rubber tube.

Step 1

Unplug the coffee pot from the wall and completely drain it of all water. Remove the carafe and set it aside. Locate the screws that holds the outer housing on the brewer. Each model will have different locations, but the majority of the screws will be on the metal plate on the bottom of the machine.

Step 2

Remove the screws and set them aside. Lift off the outer housing. Do not force it. If it won't come off easily, look for another screw that you may have missed. Each coffee pot will come off differently. Patiently look for all the ways the housing is attached to the base and remove all the screws.

Step 3

Locate the broken tube. Pull it off of the tube attachments on either end. Use firm, even pressure. Do not damage the attachments with wrenching or yanking. If necessary you can cut the tube off by slicing it vertically starting from the end. Do not cut into the attachment points.

Step 4

Fit the radiator hose (a new, clean, never-used hose) onto the bottom fitting. Slide two hose clamps over the hose to rest loosely. Measure the length of the hose to the top fitting. Cut off any excess hose with the utility knife.

Step 5

Slide the bottom hose clamp so it sits just over the end of the hose at the bottom fitting. Screw down the clamp until it is tight (about the same force as turning a door knob). Slide the upper hose clamp over the end of the hose on the top fitting and tighten the screw to secure the top side.

Step 6

Reassemble the coffee maker by reattaching the plastic housing. Replace the screws. Plug in the coffee pot and pour 6 cups of water into the reservoir. Put the decanter under the nozzle and switch the pot to the brew setting. Allow it to cycle through the water with no coffee in it. Look for leaks. If there are any leaks, you may need to tighten the hose clamps (wait until the hose has cooled completely before tightening).
