Coffee grinds can often get stuck in the valve that controls the flow of water from the reservoir to the heating element. This guide will help you remove the valve if it needs cleaning or replace it if it is broken.

Make sure your coffee maker is unplugged and empty of all water before attempting to make any repairs.

  1. KuXyD1bEaTBYZNPW
    • Turn your coffee maker over so that the base is facing up.

    • Locate the seven 13.5mm screws securing the base to the coffee maker.

    • Unscrew the screws using a #2 Phillips head screwdriver.

    • Use a screwdriver with a magnetic tip to more easily remove the three screws in the back and two in the middle.

  3. FiQUqDtLbNECXMUZ
    • Also the front two screws are safety screws: they have a 6 sided star shape with a raised dimple in the center to prevent homebodies from casually opening the machine. (probably from the Sunbeam’s (owns Mr. Coffee) legal dept.) Anyway you will need a security bit to remove the screws and not a phillips screw driver.

  4. DCpkhpZmJp3WcMPS
    • Lift base to remove.

    • If the base sticks along one edge, do not pull at an angle. Gently tug straight up while sliding a finger along the edge in order to pop the clips.

    • Locate the metal clamps.

    • Using a pair of pliers or your fingers, slide clamps away from tube opening.

    • All following steps regarding the rubber hoses should be completed for both hoses.

    Where do you get replacement hoses?

    • Using a plastic opening tool, loosen rubber hose from metal tubing.

    • Once loosened, grip the hose and pull it from the metal tubing.

    • Locate the other set of metal clamps.

    • Using needle nose pliers or your fingers remove these clamps by pinching the clamps and sliding them up the tubes.

    • Grip the hoses and pull them straight up and out.

    I have the same coffee maker as pictured. I removed the clamps, and the first hose came off easily. The hose housing the valve would not come loose. I ended up tearing the hose while trying. Any ideas for a replacement hose? And how to get this torn one off?

    Brianna Singh -

    Sadly, you mentioned the size of the screws, but failed to mention the most important piece of information, the size of the actual silicone hose (ID & OD).

    Very helpful procedure. All 7 screws on my maker were Philips heads so thankfully did not need that special tool. As I did not have a spare valve, I ran water through mine and confirmed the operation of the valve by blowing on each side. The valve seems clear and working as it should but after reassembly sadly it made no difference. I think in my case there must be something wrong with the heater circuitry and will have to dig a bit deeper to determine what failed and if it is worth (or even possible) to replace the defective part.

    • After pulling the second tube out, locate the bulging part of the hose that indicates the valve's placement.

    • Grip the tube and push the valve out the end of the hose.

    • Remember the direction of the valve when you pull it out because this valve is one way. If you insert it or reinsert it the wrong way, water will not flow through the coffee maker.

    Thanks my Mr Coffee works again

    My valve basically broke into many pieces before it would come out of the tube. I finally located a valve replacement (for a Bunn coffee maker) online. It fits, but my Mr. Coffee still sputters for the entire brewing process and steams so much that the clock is affected. The clock will work again after it dries out.

    Now what??

    cromaney1 -

    I guess you'll never drink good coffee I I guess you will never drink good coffee again. You're screwed.

    Paul Perrine -

    Where did you locate the valve to buy?

    Thomas Vavrick -

    Thanks for the post as it was very helpful. I would add that once the tube has been removed, soak it in hot water for 1 minute to allow the tube to be more pliable. Once I did this, the valve and a hefty clog of coffee debris was seen and subsequently cleaned. Replaced and the coffee maker is working well again!

    Tony Wilcox -

    The valve is a check valve. Call a local appliance parts center. they will have them. More to the point however, BEFORE doing ANY OF THIS soak the machine in vinegar & try to run part of a tank through with the acidic vinegar to dissolve hard waer or other material (could be a coffee ground) without trying to remove the valve. You can feel the lump lump in the left tube Pull the heater end off & try running water through for flow. it Run more until it runs freely. Put tube back on the metal heater tube and run a tank of water; should boil as normal. If not boil (as in heat the water) then you have a different issue. LASTLY: This is NOT a cheap coffee maker. Materials are top quality and last for decades (unlike a Cuisinart with die a short life.) Mr. Coffee: great coffee makers at reasonable price for decades. Top quality engineering balances the costs of materials & superior design give long reliable life at reasonable price. To call it cheap is a juvenile and ignorant remark made without thinking.

    Also the front two screws are safety screws: they have a 6 sided star shape with a raised dimple in the center to prevent homebodies from casually opening the machine. (probably from the Sunbeam’s (owns Mr. Coffee) legal dept.) Anyway you will need a security bit to remove the screws and not a phillips screw driver. Get a set cheap from Amazon or harbor freight.

    Q A -

    Seems I need to buy a new coffee maker once a year…this one is only 6 months old and the pump is shot…I need to change brands the next time

    Karen Schroepfer -

    My Mr. Coffee was taking close to an hour to get a full pot. I checked the hoses and valve. I rinced out with vinegar solution. Nothing really plugged .Noticed one of the hoses, one with the valve, was slightly kinked. Can I order a hose from Mr. Coffee?

    carolcoonrod -

    Great guide. Was able to follow it without any issues. However, there is power going to the appliance but is doesn't run a single drop of water through the machine. I double-checked to make sure the valve was re-installed going the right direction. What would be the cause of it not starting its cycle?

To reassemble your device, follow these instructions in reverse order.

Thank you. Beautiful in it's clarity and simplicity. The attention to detail with specific regard to the size of bolts and tools needed moved me. Too much? Maybe a little. Thank you anyway.

jdwolf1282 -

Thank you. Very well done. Do you know if I can buy a replacement valve?

Scott -

Unfortunately no. Because a lot of things are built with planned obsolescence in mind, it's very difficult to find parts. I would check thrift stores for same brand cheap coffee makers that might have similar equipment.

Mackenzie Aiken -

I have a similar model and the valve sticks at odd times...it brews half the pot and steams the rest of the water. I have cleaned, drilled the hole slightly larger that the ball seals in...with no solution! Will it it thermally pump water without the ball in the valve? Thanks!

elronhubbard -

Well firstly make sure the valve is pointing the right direction in the rubber tubing. As for your question about pumping water, that I can't answer. Try soaking the valve in alcohol then warm soapy water, there may be residue from the grinds on the ball causing it to stick.

Your best course of action might be to go to a thrift store and look for a similar model by Mr. Coffee and simply replace the valve. Drilling the hole initially might have thwarted additional attempts to make this valve work.

Mackenzie Aiken -

The plastic "valve" in the bottom (viewed from the top) is deformed, will not seat in the opening. It allows the pressure generated by the steam to escape into the water compartment, I reached down into the compartment and lifted it out with my fingers. Can it be replaced, is there a replacement for it? My Coffee Maker was new in January 2016, if that's obsolescence I'll try another brand.

Tom Bredehoft -

As far as I know there are no replacement parts simply for sale. Replacing with similar parts from another machine seems the cheapest way to deal with the problem; however excercising your power as a consumer and simply buying another brand coffeemaker may work out better in the long run for you. Sorry I couldn't be of more help.

Mackenzie Aiken -

Is the valve necessary for the coffee maker to function? What happens if you follow these steps but don't put the valve back? I'm spoiled because I used to have a Bunn. Unfortunately, the home models contain much more plastic than they used to, and I had to throw it away because it had a leak. The commercial models are found in nearly every restaurant that serves coffee.

Thomas Sisson -

Thank you so much for the clarity and simplicity not everyone is a technian and for someone like me that's the best instructions.

imayekara23 -

i just got one of these brand new and it wont even brew a full pot from the start it brews a little then just steamed the rest of the water gone would checking these valves be a viable solution the thing is brand new and already not working right but it was only 20$ but $@$* last one i had was from dollar general n worked for years till the pot broke so i thought i would get something a little nicer and low and behold from day 1 out of the box it doesnt work ........ little dissapointed that i have to fix my brand new coffee maker due to fault by the assembler or parts used

Tim Glasco -

Coffee grounds do not touch this valve, it handles brew water only. It goes bad because it is JUNK! Mr coffee needs to have a class action to get them to stop this. This is my 3rd Mr coffee in one year, same failure.

Mike Wilder -

I just read Mike Wilder’s comment and I also just had to replace my 12 cup Mr Coffee for the THIRD time this year!  Unbelievable! Before my first Mr Coffee I had a simple non programmable  12 cup Black & Decker that I had for over 5 years with no problems. I couldn't find that one again and it was looking kind of tired so  when I moved into a brand new house recently I thought I’d treat myself to a brand new coffeepot. I should have kept the Black & Decker!

Nancy Cohen -

im confused wich hoses go where and what direction does valve go and where

Bobby Larson -

torwardplate or into water holder I need more detail

Bobby Larson -

I have a similar, probably newer judging by comment dates, model. Mine has 6 screws securing the base. 4 screws are simple Philips head screws. The 2 at the front require, for some ridiculous reason, security torx bits! Security torx are designed to increase the difficulty of, and thereby deter, theft (primarily in automotives)! Why, in the name of all that is beautiful and good, does a coffee maker need anti-theft screws?! It is precisely this kind of Mickey mouse nonsense that will likely lead me to not purchase another Mr. Coffee brand coffee maker! My apologies for the tirade, I forgot this was meant to inform others that they may need the security torx screwdriver, not a review of Mr. Coffee. Anyway, thanks for help, my valve was clogged. Once I finally got into the machine this page was very helpful.

Josh Egan -

Those security Torx screws are to keep “shade tree mechanics” from accessing the innards of the coffee maker, they are not to deter theft…same reason car manufacturers use them.

gr8alarmguy -

Myhusband tried to get the valve out and it would not budge so he used a can of air and blew it out from both diresctions. Thankfully it did the trick and it no longer takes 30-40 minutes to brew a pot….Thanks so much for this step by step help guide though.

snoops927 -

Thank you, your directions for fixing my coffee maker that would not heat the water, they were right on! The tube with the check valve needed to be unclogged. I only removed the one tube with the valve and instead of removing the valve to clean it just flushed out the line. Problem solved, great directions.

Keith Block -

You can however purchase a 1/4” or 3/8” push on plastic check online that you could cut into the line. I recommend clamping as well.

youngerjrd -

Thank you for the professional style information and instructions. They helped me get through removing and cleaning the water inlet ball valve on a JW23 model Mr. Coffee. If you are going amend these instructions please include in the introduction that a typical symptom is slow or no hot water being generated. Also, when talking about the security screw the bit size needed to remove the screw for my JW23 model, was a T15 size.
