Can the illumask be reset after 30 uses

I found a review made on Amazon where someone has figured how to reset it; this means less money spent AND less landfill waste! I have not tried to reset it yet, so I do not know if this actually works, but I plan on trying it in about a week. Here are the steps:

1. Open the unit, and replace the four AA batteries.
2. Connect a wire between the POSITIVE terminal and the labeled RESET copper pad on the printed circuit board. Press the POWER ON button.
3. Move the wire to connect the POSITIVE terminal and the labeled TEST copper pad on the printed circuit board, and press the POWER ON button.
4. The counter will reset from 0 to 30 uses.

The only step that confuses me is 2, when it says connect "A" wire, do they mean connect THE wire? I'll have my dad try to reset it haha

Need to replace cord

Do you know anyone else who has the same coffee maker as you? borrow it from them and check your wiring from there.
you can get these coffee makers from amazon and wall mart.
I don't have one so cant take a photo for you.
Hopefully someone out there will see this, have one and help out.

Note: Electricity can cause serious injury even Death.
Isolate your power supply from the mains switchboard.
Switch off and Unplug your appliance from the wall socket before attempting any repairs.

if you remover the cover further and dismantle you should find clues for each wires location.
Hope this helps a bit
Good luck and take care

The heating element does not appear to be working; we've tried to clean it out with vinegar, and it worked for a few times (when we were getting rid of the vinegar taste/smell), but now it fails to heat.


Investigate these three areas if your microwave won't heat

Power Diode

A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat and you will hear a buzzing noise. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.

Testing a diode

NOTE: Before you test your diode, make sure your microwave is unplugged, and that you discharge the microwave's capacitor.

Whether it is shorted or open, a defective diode will most likely show some sign of defect. Defective diodes will usually emit an electrical burning smell, signifying its defectiveness. Also, it may have split in two, or it may exhibit a burned crack, or possibly even a blistered spot.

A shorted diode is indicated by a loud humming noise from the high voltage transformer, and no heat produced when a cook cycle is initiated. Whereas little or no heat produced in your microwave, with an absence of a humming noise is indicative of an open diode. In either case, the diode has to be replaced.

With your microwave unplugged, and your capacitor discharged, use extreme caution to remove the lead that leads to the capacitor. You can leave the ground connection attached. The side of the diode that goes to the ground is usually marked with a dot, stripe, or arrow. Set your ohmmeter to R x 10,000 or higher. Touch the positive meter probe to the anode and the negative meter probe to the cathode to measure the resistance across the diode terminals. Remember that the cathode is on the side that goes to the ground, which is often marked by a dot, stripe, or an arrow.

A normal diode, that is a non-defective diode, will read anywhere from 50,000 to 200,000 ohms. Differences in microwave make and model account for this large range in resistance readings.

Reverse the meter probes and measure resistance while touching the positive probe to the cathode and the negative probe to the anode. Reversing the probes like this should result in a reading of infinity. Unless a bleeder resistor is present. The presence of a bleeder resistor would produce a reading of the value of the resistor.

High Voltage Capacitor

A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating but you are hearing a buzzing or humming noise. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.


A defective magnetron is the third possible cause of why your microwave is not heating, but you can hear a buzzing noise. Test your microwave's magnetron. Replace it if it is defective.

Testing a magnetron

NOTE: Before you test this component, make sure your microwave is unplugged, and that you have discharged the capacitor.

There are two tests to conduct in order to determine whether or not a magnetron has become defective. If you receive results other than what are detailed below, you will have to replace your microwave's magnetron. Each test is described for you here:

TEST 1: Locate your magnetron and label each of the wires attached to it so that you know which wires are to be replaced where. Set your ohmmeter to the lowest resistance scale. Take a resistance measurement between each of the magnetron's terminals by touching each probe to one terminal each. Reverse the probes and take a second resistance measurement. Each measurement should read less than one ohm.

TEST 2: Set your ohmmeter to its highest resistance scale. Touch one of the meter's probes to a magnetron terminal. Touch the other probe to the metal magnetron housing. Take special caution to not touch the two probes together. This could result in an inaccurate reading. This test should produce a reading of infinity - indicating an open circuit.

Read the tips on the below links on how to replace your microwave oven's diode and how to discharge the capacitor.

I hope the above is helpful.

I've got a faema E91/A 3 group espresso machine. I'm testing the machine to see if all works. I've ran power by using a 10 gauge cord hooked up to 250v 30 amp. the cord is about 60ft long. Everything...

the original cord how many wire have? on the label what writes? if you have 5 wire (blue= null or neutral, green whit yelo= grounding, brown, black and grey= phases, is posible to have a red wire instead of grey, black or brown wire), on the blue wire whit one of the phases must have 220 V, on the brown whit another phase you must have 380V, if you had a bad conection is posible to damage something in electronic automatisation of the espresso machine, that machine must be conected in a water suply whitin a softner an befor use is posible to must be triggered manually. by the way, this machine must be proper instaled by a specilised personell beacause it is the risc of electric injuri and other bad things. your E1 is posible to be a temperature probe damaged or because of water mising and in 20-30 min. the machine was reaced a high temperature and safety thermostat has occurred. the best you can do is to call a repairman to solve this, if you try to repair your self it is posible to make worst.

Total dead, no power? Changed fuse in plug and tried fuse in kettle and that's ok, power at socket ok, any ideas? it doesn't start; no lights. where is the fuse?  how an i find it

This is quite an easy problem to fix. Whats happened is the water heater has overheated and tripped the power as a safety measure.

Take off the Left hand cover, there are 4 torx screws. You will see the water heater. with what looks like 2 circular teminals held on the side with a metal strap.

these are one shot thermal cut outs. the same as on a tumble drier.
Tassimos are over engineered and really only need one thermal cut of. if there are no lights on the front, the brown wire has tripped. if there is light and no heat the blue wire has tripped.

What I did was swap the brown wires over to the trip that had the blue wires on, so you still have a thermal trip. and bridge the blue wires together and taped them up - voila it works again. DO NOT CROSS THE BROWN WITH THE BLUE> BOOM!

to do the job properly take off the thermal trips and go to an applicance repair shop. of they dont have them on the shelf i would suspect they can get them they are very generic. try not to lose too much of the white thermal paste as this helps with the cut off. if you do lose some its the same as used on CPU heatink compound. put them in and replace the strap and re assemble.

I have a Faema special. model no.537212 I need the schematics

I have no clue about this product, but at the terminal board how many
wires come from machine to the board,or just wires coming from machine. A 220v, should have 2 hot, neutral,gr, so 4 wires. Depending
on what it looks like, the wires come from machine to a board or just wires.then the colors of those wires.

You should send them an email asking for help or schematic.
I posted there website below. Sorry could not help further.

Compatability with US 240v 60HZ 1phase wiring?

It should work OK The US system is 240V single phase (split) into two 120v branches. Aussi system is hot on both sides, with a center ground (a virtual ground system) Connect the 2 main wires (usually brown and blue) to the 240 (black and red), and connect the grounds (Green/yellow to green), and leave the neutral wire off.

Machine won't turn on - no power!

With the machine facing you, the circuit board is mounted on the left panel. Simply unscrew the grey plastic and you will see it inside a clear case.
The two grey conical inserts are recessed into the machine (next to where water drips out into the coffee), one on each side. Just use a long philip head screwdriver to unscrew them until they drop down.
They hold the top lid in place. Now push the top lid towards you,
pretty easy. Also take out the water tank in the back (the one swing out) to make room to access the circuit board. With the machine back facing you, open the water tank, use your finger to pull the plastic tap. One side of the tank will just drop, and just jiggle the tank out.

Remove the circuit board case, pull out all the wires with a piler,
they are sort of tight, but you can pull them out carefully. Label them so you won't mix them up.

With the circuit board out, I probed around with a multimeter. I found ZD6, a zener diode, part # 1N4749A didn't give me a 0.46V reading. (there is another zener diode with the same part # that gives 0.46V (ZD1). ZD6 is next to two blue electrolytic capacitors. Unsolder ZD6 from underneath and replace it.
It is like 5 cents, definitely not freaking $40.
