Introduction

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.

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

After pulling the second tube out, locate the bulging part of the hose that indicates the valve's placement. 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. Remember the direction of the valve when you pull it out because this valve is one way.

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.

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

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.

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!

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.

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.

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.

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

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
