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.

  2. Locate the seven 13.5mm screws securing the base to the coffee maker. Unscrew the screws using a #2 Phillips head screwdriver.
    • 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. 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.

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?

Scott - crwdns2853112:0crwdne2853112:0

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 - crwdns2853112:0crwdne2853112:0

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.
