Bypassing an EMI Filter on a Washing Machine?

10/12/2017 12:04 PM

Hi,

Im trying to bypass my emi filter on a washing machine and read on this forum that i can do that by disconnecting the H & N connectors on the filter. However on my filter it has 2L Brown, 4N Blue, 1U Black, 3U Orange and an earth Green/yellow. Can anyone tell me which of these are H & N? Cheers!

Not sure why you'd even want to do this.

Reasons for requiring EMI suppression filters - Murata

Why not let the forum in on some pertinent things, like the make and model number of your dryer if you can't find the schematic yourself. That might help.

This is sort of like the TV shows where they have to decide whether to cut the blue wire or the yellow wire to defuse the bomb.

I got told by two washing machine repair guys that i could bypass it safely whilst they ordered me a new one.

Pay them to bypass it then, and when it goes phut you then have a claim in most jurisdictions' civil laws. I mean, why bother the lads and lasses at CR4 if they already know what to do?

Thank God you did not cut the red wire! That shorts out the timer, and things go "BOOF".

Good one! I think I saw this on Top Gear. A PSA for bicycle safety, right?

OH the horror! O'Neil was color-blind or he would have picked green, obviously.

Had this been a Fredski, " caption this ",,

The English pilot episode of Mac Guyver, didn't exactly go as planned.

Come one James! If you read the OP's notes, he clearly states that there is no Red wire. And you know as well as I do that EMI Filters on Washing Machines don't have a Red wire. Remember from EE 201? Washing Machines made before 1953 do not contain Red wire, due to the dye. Red dye #40 is a known carcinogen and back in 1953, they used cloth napkins and washed them in their washing machine. A law was proposed by Strom Thurmond to remove red dye #40 from washing machines. It passed both Houses and was signed into law. Since then, no washing machines could use Red wires inside of them.

Probably a communist plot to remove red dye #40 from California(te).

That is why professors have colored chalk.

Storm Thurmond - a name you hear every day.

I am impressed you know about red dye #40. Red dye #4 is OK, since it has no decades in it, and cannot be decadent.

It seem like the OP wants to turn his appliance into a RFI generator.

One can only wonder at the thinking (or lack of it) that has gone into this.

If it didn't need a filter, the manufacturer wouldn't have put one in there.

First rule of servicing: replace the defective component, do not simply by-pass it.

Do not do it. It is there for a reason, unless you like noisy radio reception.?

This is easy!

The Brown wire is a thermoflux routing dielectric controller. It allows the washing machine to operate while the drum is out of congruence. Don't cut that wire!

The Blue wire is a density modulation distribution network capacitor. It allows the washing machine to detect the type of clothing you're washing and how quickly to let the soap begin to suds up. Don't cut that wire!

The Black wire is the Hot and if you cut it, make sure the power is off. Remember that in AC home wiring, the Black is hot. However in DC electronics, the Black is the negative, but since AC doesn't have a true negative, it becomes the Hot.

The Orange wire is for the refractive imaging condenser recipricator. It allows neutral imaging of the wash basin drum and condenses the leaking electrons and protons into a plasma gel. The nucleotide present in the subcutaceous variable is needed to get the stains off your clothes, so Never cut the Orange wire!

The Green/Yellow wire is Earth or in electrical terms, the wire for sending stray electrons back. There is an electron counter in the wire, which counts the number of electrons that escape from the hot or cold water. If it's hot water, the system compensates for more electrons breaking free. If too many electrons escape, the Hunter Valve is opened and the electron catcher is allowed to enter the washing machine. You should cut the Green/Yellow wire, but only if the machine is fully stopped and the red and green light on the control panel are blinking slowly. Do not do it if they are blinking fast!

If you remove the EMI filter, you need to be careful. Here in the US, there are laws against doing things like this. We have a strict consumer products enforcement department here and they're not very nice when they catch you. The biggest department is the illegal tag removal. It's clearly written on the tags, yet people must want to push things and remove those tags. The second largest department is the sticker removal department. Those stickers were placed there for a reason and should not be removed. The biggest culprits are the California Cancer warning stickers. Every new car has one of these on them and it clearly states that the stickers should not be removed. Look at how many cars don't have their stickers!

I don't know the laws in your country, but please check with your Federal, State, County, City and Local Municipality codes. If you live in an area where there's an HOA, check with your CCR's to make sure you're in compliance.

The last thing we want to see here is another person arrested and thrown in jail for removing an EMI filter!

Good luck.

colinfloss, glad you got the message. Not knowing how tho find hot and cold or life and neutral tell me that you are busy with something you are totally oblivious about. Stick to what you know, leave the EMI filter to do its job.

Wow! You actually bought what Autobroker was selling by yanking your leg, and you bought hook, line, and sinker!

Cut the black wire, and save yourself all the misery! Just trip the breaker first, you know, safety first.

EMI filters are there to remove the stains from your radio listening pleasure. They malfunction because they will not filter out liberals.

After such an eloquent answer, maybe we should ask gutmonarch to provide his expertise?

I think he's still in jail for removing the car stickers. He's the one who refused to pay the fine and the judge threw the book at him, right?

Now we all know why you sell so many cars.

Anybody who can shovel it that high and keep it in a pile has to be a good salesman!

I'm guessing that you believe the EMI filter is tripping your RCD (GFCI) circuit breaker. Also that your color coding of wires is European. So Blue is Neutral, the input Hot line is Brown. You need to use an ohm meter to determine which of these input lines the Black and Orange connections should be connected to. If you get low ohms between Blue and Orange (on the isolated EMI assembly), then short these, if between Blue and Black then short these, the Brown then is connected to the other connection. Just leave the green/yellow safety ground connected. This will isolate the Hot and Neutral from this EMI module i.e. you are disconnecting these 4 wires to remove the EMI sub-assembly from your circuit. Hope this helps.
