My girlfriend and I recently purchased an inexpensive Mr. Coffee coffee maker (Model JWX27-A), which has a majority of the features we wanted, including one that we did not want. This was the loud beeping/notification that occurred after a pot of coffee had finished brewing. Since we sometimes get up at different times and due to the ridiculous volume of this thing, I decided to see if I could disable it. I did a fair amount of research hoping the manufacturer included some sort of secret button-combination to disable it, but they didn’t. Our previous Mr. Coffee maker actually had a switch to accomplish this, but I’m sure some jackass executive decided to remove the switch and therefore lower their manufacturing costs. Seriously, do companies consult with end-users anymore? Anyway, I decided to take the next step and physically modify the pot to meet my needs. Below are the general steps you can take to do the same (sorry for not including photos, but I didn’t think about it during its disassembly):
**DISCLAIMER: These steps could possibly render your coffee maker useless and most certainly void any sort of manufacturer warranty. Swim at your own risk. Don’t pick up wooden nickels. Wear eye protection. You get the idea. **
In short, the annoying beeper/speaker lives behind the front control panel. These steps will help you remove the control panel and access the speaker for its ultimate removal.
- Unplug the coffee maker (if you did not think to do this, you should probably not proceed any further).
- Empty the pot of any water (if you did not think to do this, you should probably not proceed any further).
- Remove the carafe.
- Remove the filter basket.
- Remove the water sprayer swing arm. This is attached by one small screw and simply pops off the plastic stem/tube after the screw is removed.
- Flip the entire unit upside-down and remove the 5 recessed screws that surround the opening (by “opening” I mean the hole where magical coffee typically exits the basket and enters the carafe). It may look like there are only 4 screws at first glance, but there is a 5th towards the base.
- Flip the unit upright again. (This is the part that stumped me for a few minutes.) There are 2 “hidden” screws that hold down the entire upper portion of the machine. The parts that we’re wanting to remove are essentially the doors + the molded bucket that hold the filter cup/basket. You’ll remove this as a single “piece” (don’t try to pry off the 2 flip doors). The screws are covered by 2, black plastic “plugs” which cover the screws (probably to keep them from getting wet and rusty); one plug per screw. I used the awl on my pocket knife to dig into the center of the plugs just a little bit and then they popped right out. Once you remove the plugs, you can then remove the screws. You can now remove the upper plastic piece. If you were able to salvage the plugs, you’ll want to pop those back in place during reassembly.
- You should now have access to the control panel. Remove the 2 screws that hold the panel to the coffee maker.
- You’ll now see 4 small screws that hold the PCB (printed circuit board) to the panel. Remove those, but be aware of the fact that the buttons on the panel are loose and can fall out. It’s easy to put them back if they do, but just keep your eye on them. You don’t want to put this thing back together and then realize you’re missing buttons.
- Once you expose the PCB, you’ll see the bane of your existence, the speaker. It is a black, circular piece of plastic that looks like a thick washer. If you simply want to reduce the volume, I suppose you can probably just wrap this part in electrical tape (assuming you don’t use so much that you can’t reassemble the panel). I chose to eliminate it altogether, so using a small pair of pliers, I gently torqued the component in a clockwise / counter-clockwise direction until it broke free from the board. It was still attached to a single wire, so I snipped it with some wire cutters. (Honestly, at that moment, I felt my odds were about 50-50 that I was still going to have a working coffee pot.)
- Reverse all of these steps to get it back together and you’ll have a quietly brewed pot of coffee the next morning.
