    My grinder slips from time to time (the motor turns with no grinding sound, and no ground coffee comes out). I want to open it up to see what the problem is, but don't know how to open it. I don't see any screw. Seems like they assembled it by snapping parts together.
    If anyone knows how to unassemble it, please help.

My grinder went from bad to worse and finally stopped grinding (with the motor still buzzing but absolutely no grinding). Knowing I had to do something or throw it away, I pulled the clear plastic bean reservoir upward and separated it from the grinder body. I looked down the hole where beans go down to the grinder and found packed coffee ground blocking the hole. I cleaned the whole thing, put the reservoir back, and my grinder now works like new :-)

Taking this thing apart is not easy. It may require a Torx bit, but it takes a 4 to 6" long extension. The second suggestion worked for me. I had used the bent handle of the spoon to try to loosen packed coffee deep inside the grinder with little success. Turning the machine over and rapping on it loosened a lot of partially ground beans and packed coffee. Works good now. Will do this regularily now

Your local hardware store sells kits with tamper resistant bits. Ace has them, too. There are two kinds of bits generally used Torx which is simply a 6 sided bit and tamper resistant which adds a button in the middle of the "star". I've seen both in this type of unit. Determine if you need the button style by looking at it. All turn counterclockwise to remove.

Oh...cafelover, take the unit apart by removing the burr assembly, cleaning it out and reassembling...that will likely cure your problem. If you want to do a bit more...simply turn the empty unit over a tap it on a newspaper covered surface.

Hi, my house alarm ready light is not on since I opened the anti tamper box, when the box opened the alarm went off, I put in the entrance code number, the alarm went quiet, since then the ready light

Hi Terry,
Most alarm systems require you to reset the tamper alarm.
Most systems will reset the tamper simply by arming the system and then immediately disarming the system. However, you MUST make sure that the Tamper circuit you tripped is closed. If you removed the cover on the panel, make sure the tamper switch for the cover is in the correct position and that the cover is pressing the switch and closing its contacts. If you are trying to arm the panel with a cover off, the tamper circuit will not reset unless you defeat the tamper switch. Just make sure you remove the defeat when you replace the cover. You may also wish to try a google search on the type and model of panel you have so you can download a copy of the manual to check on the reset procedure. We also need to know what brand and model the panel is so we can help you further..

Wait... you cannot replace light switch with outlet receptacle.
You have to test wires first.... then Hot wire connects to brass screw on receptacle,,,, and neutral wire connects to silver screw ( ground to green screw) ... you got several important details right, but you have to identify hot and neutral wires first.

I have one AudioSource AmpOne amplifier. Someone has tampered with the transformer and has changed its original windings. Can anyone help me know what is the correct AC voltage that should be present

If I where you to be on the safe side, I would order a brand new transformer. Transformers are safety parts anyway and should also be replaced by exact types recommended by the manufacture of the amp. It's not worth tampering with the thing yourself only to have it burn your house down a few days later for want of spending some money on a new one!

We are trying to install a Leviton No. T5225 Combination switch and tamper resistant outlet. We are replacing the single light switch with this new one. We have a red, a white, and a black wire. When we...

You are installing a combo device with switch and outlet.
The outlet is tamper resistant so a child cannot stick a key into outlet and get shocked.
For the outlet to work, a 2-prong plug must be inserted.

Wiring the device:
Electricians don't guess, they test.
Device has different colored screws: dark, silver and brass.

Separate wires for testing.
Do not unwind wires that are twisted together.
White wires that are twisted together and located in back of box are included in testing.
Use ordinary 2-lead tester.
Tape tester leads to wood sticks to keep hands away from power.
Turn power ON.

Test each wire to bare ground wire.
Tester lights up on Hot wire. This wire connects to dark screw.

Hot is identified.
Test Hot wire to all other wires, except bare ground wire.
Tester lights up on Neutral wire. Neutral connects to silver screw.
If you do not have a Neutral wire, then outlet will not work for that location.
You can get the outlet to work by connecting bare ground to silver screw, but that is violation of code.

Last wire goes to Load (light, fan, motor).
Load wire connects to brass screw.
In your case, this is red wire.

Motor will make a sound , but will not pump any water

it sounds as if you may have something jammed in the impeller blades, if you have small kids, look for small toys (leggos, plastic wrenches, etc) stuck inside the input tube or the blades themselves.
PLEASE turn off power first and drain (if needed). the pump housing should come apart with a screw driver, but you MAY need tamper resistant bits and a bit driver. if no kids, then look for small debris like twigs or such ( I have even found bottle caps in some units that I've taken apart!!).

On my babyliss type S47b, special screwdriver???

The screw may be triangular, or Torx (star pattern), or even 'pin-in-Torx', which all require special tools. They do it to prevent people from opening them up. But you can buy the tools, and for triangular screws I ground an old screwdriver down to match the shape!

Those screws are called 'Tamper Proof' or 'Tamper Resistant'. If you google those you'll find tool sets that will open dang near anything.
