The torx bits are called tamper proof bits. I bought my set a Lowes.

If the screw has an internal star configuration then it is a torx screw. torx drivers are easy to come by. you may even find an allen wrench might fit it. another is a three slot driver, then there is a one way screw that has flats for screwing in but ramps that push the regular screwdriver off it. use a diagonal cutting plier and press it tightly in the screw head and rotate counter clockwise.

How do I remove the water tray on a Bunn B10B?

You can verify whether there are screws in the holes, by using a bright light for illumination and peering inside. If there are phillips head screws in the holes, you may need to use a metric screwdriver to remove them. The cross slots may require this.

Replacing the pipe unit

Here's how it works....
An initial short run of the pump draws water from the reservoir into the boiler where it is heated by an electrical heating coil. There are two outputs from the boiler, one from the top runs through a pipe to a steam valve. When the steamer handle is turned, the steam valve opens and steam is piped out through the steam tube for frothing milk. The second output from the boiler is on the underside and is stopped by the normally closed flow valve. When the water in the boiler reaches the right temperature, a sensor switches on the OK light. When the light is on, the user pushes the pump switch and more water is pumped from the reservoir. The pressure in the boiler increases because the pump is trying to push in more water and this forces the spring loaded boiler flow valve to open allowing hot water to run out. As the sump filled with ground coffee is fitted to the boiler output, the water is forced through the coffee and out of the sump where it pours into a waiting cup.
When enough coffee has been poured, the user switches off the pump. The boiler pressure falls and the spring on the flow valve pushes the valve shut again.
------------ The first three steps aren't strictly necessary for disassembly however if you're using a long handle screwdriver then removing the base makes it easier to gain better access to some of the screws.
Step 1. Remove the screw on each base arm.
Step 2. ... then lift and remove the arms.
Step 3. Remove the two screws on the base of the unit. Unlike in this photo I would recommend you avoid resting the machine on its back unless you are sure it has been completely drained. The black plastic base can now be pulled away allowing easier access to some of the screws that will be removed later.
Step 4. Undo the two screws on the top rear.
Step 5. Remove the coffee tamper by pulling and twisting.
Step 6. Remove the three screws. These are anti tamper screws and are star shaped with a nipple in the middle.
Step 7. With these screws removed, the top may be lifted away. The hotplate on the top section is still connected by a couple of thin wires so lift it carefully.
Step 8. To help with shifting the top out of the way, disconnect the hot plate/boiler heater connection. This will allow you to push the top of the unit away giving you the room you need to get inside.
Step 9. Unscrew the electrical safety earth and move the earth wiring out of the way.
Step 10. Use some long nose pliers to pull out the circlip that holds the boiler inlet pipe in place. Pull out the pipe to disconnect it from the boiler once the circlip has been removed.Step 11. Unscrew, remove and clean the diffuser.
Step 12. Remove the two screws . The black plastic underside casing can now be pulled away (plastic tabs need to be pushed aside ). Step 13. Pulling away the plastic underside once screws and tabs are removed.
Step 14. Loosen the four black Torx (star shaped) boiler screws . Water in the boiler may leak out at this point so ensure the unit is upright and a towel is placed underneath.
Step 15. Remove the four nuts (three arrowed) from the underside of the boiler unit.
Step 16. Lift up the top of the boiler assembly along with the steam outlet and place to one side. The two halves of the boiler assembly are sealed with a rubber gasket which should remain attached to the upper housing. Make sure this is properly in place when reassembling.
Step 17. The lower boiler assembly can now be lifted out.

Wont heat or brew!!

Make sure the coffee maker is unplugged there's 120 lethal volts inside when plugged in!

This unit has a replacable thermal fuse. It's a "Microtemp" Thermal Cutoff Fuse G4A00. You can buy five on eBay for $2.70. There are two on this unit and they are in the base concealed inside a 3" white mesh that runs alongside the heater. You will need a security fladebladed screwdriver that you can make by filing a notch in the center of a regular screwdriver.

Is a specil tool needed to open a Cusinart grind & brew coffemaker? I have a power problem.

You need to use a Torx T-9 Tamper Proof screwdriver to remove the four screws on the bottom of the coffee maker. It is a star bit with a small hole in the center.

Allen screw B&D spacemaker ODC325

By sticking a small screwdriver where the pin is inside the torx type fastener, I was able to break the pin. Then a torx 10 or 15 will easily unscrew the screw. Maybe an allen wrench would as well, if it would fit.

A rather costly 35 dollars or so (plus shipping) heating element incl thermostat is available, if indeed that is the problem. You might as well find someone selling a used unit on ebay, after paying that much.

How to disassemble Krups FND1 Expresso maker

the krups machine can be opened with a special screwdriver. i made my own by taking a standard flat-head and carving out a notch in the center with a dremmel and cutting wheel.
with all screws removed, i believe the only other thing in your way is the power knob which has to be removed to get the top off. there is a release on the inside part of the shaft. with the bottom of the machine open, you will have to reach inside to activate the release and then pull the knob off. after that, the top should open right up.

ECM20 not working properly

I fixed one of these for a friend yesterday.

The valve that selects coffee or steam has fairly small holes in it and if the pressure vessel gets contaminated with scale or sludge of any form, it is easily clogged.

I was able to finally fix it. It required that I disassemble the entire unit to get access to the valve portions so that I could inspect and clean it. Too much trouble to relate how it works, but the key things are that the unit has to be taken completely apart. If you aren't good at doing that sort of thing, then you should buy a unit that is more maintainable.

To disassemble...

Remove all obvious and easily removable parts from the unit.

Using a Torx #15 security bit, remove 6 screws in bottom. (Two are under rubber feet in the middle.)

Using a 12" Phillips screwdriver, remove 4 screws deep inside well of unit. THey are around the back side of the unit and they hold the top on.

A hole underneath where the valve knob attached is visible inside the well. Rotate the valve knob until you can see a small depression clip that holds the valve knob on. Using the long phillips driver, push on the tab while removing the knob.

Remove the screw in the center of the water spout under where the carafe goes. Remove the metal screen. Remove the rubber gasket. Remove the four phillips screws in the perimeter of the carafe spout. ( A short phillips screwdriver is required.) Remove the entire plastic piece once all 4 screws are out.  It is hard to dislodge..

Pry up the top cover. There are several places where it binds. These include around the filling hole, around the steam vent exit, and around the knob. Work it until it is off.

Remove the pilot light by removing the single phillips that holds it in place.

Work the microswitch loose by examining and manipulating the two little tabs that hold it in place.

Remove the microswitch holding bracket by removing the two phillips screws.

Remove the plate that holds the valve plastic in place by removing two phillips screws.

Remove the valve plastic. Examine it and look for gunk stuck in the tiny holes. Clean it out. A lot.

(If you're really ambitious, take off the screws holding the pressure vessel in place, disassemble it, clean thoroughly, and reasssemble. (If you do this, you'll have to disconnect the wiring at the bottom of the unit's base. Make a note of what goes where to facilitate reassembly.)

Reassemble, going backwards.


Celebrate if you are successful. Otherwise, curse George Bush for getting us in this mess. Elapsed time should be in the 1-2 hour range, worst case.

Remember... unplug the unit.  You are dealing with a heated pressure vessel, so reassembly should be done carefully.  Obviously, work only on a cold unit.  A small flashlight and magnetic screwdrivers are useful.  Toothpicks make good cleaning aids for the valve.

Boiler U/S?


Take off the water tank, you will se one screw in the chassis, look in the beenhopper and there will you see two screw, loosen this to. Open the door and look up to the right corner and left corner there will you see one screw in each corner, loose this. take of the steam knob. Take of the top.
Look at the right corner and you will see one screw that has to be loosen. If you have to change the boiler you can put a screwdriver in the hole on the right side between the top and chassis and ****, now you can lift up all and work with it on the table.

Unit heats but water doesn't come out

I had the same problem. I read this article and was able to figure it out the probem: The one way valve and the heater pipe in the bottom of the unit are extremely calcified. I opened the bottom by removing the four little "security" screws. I used a little tiny flathead screwdriver because I didn't have the proper "star security screwdriver and it worked fine. Next, I removed the two orange hoses and soaked them in white vineager. The shorter intake hose contains the one way valve. make a note of which way you remove this hose 'cause it has to go back in in the same direction. Next I propped the unit on its side so that I could put some vineager in the heater pipe and let it soak in there. Next I blew into and sucked air out of the one way hose and then rinsed both hoses thoroughly. Then I used a little piece of a wire coat hanger to scrape out some of the junk in the heater pipe, (especially on the heat side) followed by a little pipe cleaner to get it extra clean. Then I put it all back together. Be carefull that the hoses are sealed ok. I actually cut a little off of them to get a new seal on the side that connects to the heater pipe. There wasn't much room for error though. After getting it all back together I ran a few full pots through it of 1/2 vineager 1/2 water and then a couple of just water. Probably a good time to change the water filter inside the unit too. Also, from now on I'll make sure to use the self cleaning mode more often. Good luck. Kevin
